Syntax

TipqAMQP

Remarks

The AMQP component provides an easy-to-use AMQP 1.0 client implementation. The component supports both plaintext and TLS-enabled connections over TCP.

Connecting

The component implements all three layers of the AMQP 1.0 transport protocol, so the first step is to initiate the overall connection. Set the ContainerId property and call the ConnectTo method, passing it the server's hostname and port number.

Once connected, the next step is to create at least one session, which can be accomplished by using the CreateSession method. The component allows creating any number of sessions, up to the limit specified by the MaxSessionCount configuration setting.

Connecting and Creating a Session amqp1.ContainerId = "testClient"; amqp1.ConnectTo("amqp.test-server.com", 5672); amqp1.CreateSession("TestSession");

After creating a session, the next step is to create one or more links (which are created in the context of a session) so that messages can be sent and/or received. Links are unidirectional, so each one has a sender on one end and a receiver on the other.

The component can function both as a sender node (by opening sender links) and as a receiver node (by opening receiver links). But keep in mind that, since the component is implemented as an AMQP 1.0 client, it must be the one to open links (said another way, the component cannot accept any link requests made by other peers).

As with sessions, the component allows creating any number of links for each session, up to the limit specified by the MaxLinkCountPerSession configuration setting.

Creating Sender Links

The LinkReadyToSend event will fire when the newly created sender link is ready to send messages.

Creating a Sender Link amqp1.OnLinkReadyToSend += (s, e) => { Console.WriteLine("Link '" + e.LinkName + "' is ready to send messages!"); }; amqp1.CreateSenderLink("TestSession", "TestSenderLink", "TestTarget");

Sending Messages

At minimum, the MessageValue and MessageValueType properties must be set. All other properties are optional, though specifying a unique value for MessageId is recommended. (If the GenerateMessageId configuration setting is enabled, the component will generate one automatically when the message is sent.)

Once the Message property's properties have be assigned as desired, call the SendMessage method, passing it the name of an existing sender link on which the message should be sent.

The MessageOut event will be fired when the message has been sent (and acknowledged, if MessageSettled was set to false). The MessageOutcome event may also fire, if necessary, once the receiver reports the outcome of the message.

Refer to SendMessage, MessageOut, and MessageOutcome for more information.

Sending a Message amqp1.OnMessageOut += (s, e) => { Console.WriteLine("Message with Id '" + e.MessageId + "' has been sent on link '" + e.LinkName + "'."); }; amqp1.Message.MessageId = "TestMessageId"; amqp1.Message.Value = "Hello, world!"; amqp1.Message.ValueType = AMQPValueTypes.mvtString; amqp1.SendMessage("TestSenderLink");

The ResetMessage method can be used to reset the Message property's properties to their default values.

Sending Composite AMQP Data

The component supports sending composite AMQP data in a message through the use of JSON with a well-defined schema. Refer to the SendMessage method's documentation for more information and examples.

Creating Receiver Links

The ReceiveMode property controls which receive mode newly-created receiver links will use; refer to its documentation for more information.

After ensuring that ReceiveMode is set as desired, call CreateReceiverLink, passing it the name of an existing session, a unique name for the link, and (if necessary in your environment) the name of a source for the sender to route the link creation request to.

Creating a Receiver Link // Creating an automatic receiver link. amqp1.ReceiveMode = AmqpReceiveModes.rmAutomatic; amqp1.CreateReceiverLink("TestSession", "TestAutoReceiverLink", "TestSource1"); // Creating a retrieve-based receiver link. amqp1.ReceiveMode = AmqpReceiveModes.rmRetrieve; amqp1.CreateReceiverLink("TestSession", "TestRetrieveReceiverLink", "TestSource2");

Receiving Messages

For receiver links created in retrieve-based mode, the component will attempt to "retrieve" a message each time the RetrieveMessage method is called (optionally timing out after a time, if RetrieveTimeout is non-zero). When calling RetrieveMessage, pass it the name of a retrieve-based receiver link.

Regardless of whether a messages is received automatically or retrieved, any incoming message will cause the component to fire the MessageIn event and update the ReceivedMessage property's properties.

When the MessageIn event fires, its State event parameter can be used to specify the outcome of the message, which the component will then transmit back to the sender (as well as self-report by firing the MessageOutcome event). Refer to MessageIn for more information.

Receiving a Message // For automatic receiver links, only the event handler is necessary. amqp1.OnMessageIn += (s, e) => { Console.WriteLine("Message with Id '" + e.MessageId + "' has been received on link '" + e.LinkName + "'. Value:"); Console.WriteLine(amqp1.ReceivedMessage.Value); // The message state is already set to the "Accepted" outcome by default, but we'll set it again // for the purpose of this example. e.State = 0; // 0 = Accepted. }; // For retrieve-based links, it's also necessary to call RetrieveMessage(). It is recommended that the // RetrieveTimeout property be set to a non-zero value (60 seconds is the default) so that the retrieve // request will eventually time out if the sender doesn't have any messages available to deliver. amqp1.RetrieveTimeout = 60; amqp1.RetrieveMessage("TestRetrieveReceiverLink");

  smSASLExternal=3
};

Default Value

smSASLPlain

Remarks

This property controls what authentication scheme the component should use when connecting to the remote host.

Valid values are:

• smNone (0)
• smSASLAnonymous (1)
• smSASLPlain (2) - Default
• smSASLExternal (3)

This property is not available at design time.

Data Type

Integer

Connected Property (AMQP Component)

This property indicates whether the component is connected.

Syntax

__property bool Connected = { read=FConnected };

LocalHost Property (AMQP Component)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

__property String LocalHost = { read=FLocalHost, write=FSetLocalHost };

Default Value

""

Remarks

This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the component initiate connections (or accept in the case of server components) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the component is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

Note: LocalHost is not persistent. You must always set it in code, and never in the property window.

Data Type

String

LocalPort Property (AMQP Component)

Default Value

0

Remarks

This property must be set before a connection is attempted. It instructs the component to bind to a specific port (or communication endpoint) in the local machine.

Setting this property to 0 (default) enables the system to choose an open port at random. The chosen port will be returned by the LocalPort property after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this property when a connection is active will generate an error.

This property is useful when trying to connect to services that require a trusted port on the client side.

};

Default Value

rmAutomatic

Remarks

This property controls which receive mode newly created receiver links should use to receive messages from the sender. Valid values are:

• rmAutomatic (0 - default)
• rmRetrieve (1)

Receiving Messages Automatically

In this mode, receiver links will be created with the amount of credit, and the credit threshold, specified by the DefaultCredit and DefaultCreditThreshold configuration settings. Anytime the link's credit reaches the credit threshold, the component will automatically set it back to its initial value.

Retrieving Messages On-Demand

In this mode, receiver links will be created with no credit (regardless of what DefaultCredit is set to). When RetrieveMessage is called, the component will supply the sender with a single credit and then block until a message is received (if the RetrieveTimeout property is set to zero).

If RetrieveTimeout is non-zero, the component will only block for the specified number of seconds; once that time expires, it will instruct the sender to consume the credit. If the sender chooses to consume the credit by incrementing the value of the LinkDeliveryCount property rather than by sending a message, then the component will throw an error indicating a timeout.

Refer to RetrieveMessage and RetrieveTimeout for more information. amqp.ReceiveMode = AmqpReceiveModes.rmRetrieve; amqp.CreateReceiverLink("SessionID", "ReceiverLinkName", "SomeTarget");

If SSLServerCertStore has a value, and SSLServerCertSubject or SSLServerCertEncoded is set, a search for a certificate is initiated. Please see the SSLServerCertSubject property for details.

Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

When the certificate store type is cstPFXFile, this property must be set to the name of the file. When the type is cstPFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

This property is read-only.

When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.

This property is read-only and not available at design time.

Data Type

Byte Array

Timeout Property (AMQP Component)

This property includes the timeout for the component.

Syntax

__property int Timeout = { read=FTimeout, write=FSetTimeout };

Default Value

60

Remarks

If the Timeout property is set to 0, all operations return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.

If Timeout is set to a positive value, data is sent in a blocking manner and the component will wait for the operation to complete before returning control. The component will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of Timeout seconds.

The component will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If Timeout expires, and the operation is not yet complete, the component raises an exception.

Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

Data Type

Integer

User Property (AMQP Component)

A username to use for SASL authentication.

Syntax

__property String User = { read=FUser, write=FSetUser };

Default Value

""

Remarks

This property contains a username to use for SASL authentication.

This property is not available at design time.

Data Type

String

CloseLink Method (AMQP Component)

Closes a link.

Syntax

void __fastcall CloseLink(String Name);

Remarks

This method closes the link named Name and removes it from the Links properties. If no link with the given Name exists, an error will be thrown.

CloseSession Method (AMQP Component)

Closes a session.

Syntax

void __fastcall CloseSession(String Name);

Remarks

This method closes the session named Name and removes it from the Sessions properties. If no session with the given Name exists, an error will be thrown.

Any links open on the specified session when this method is called will be automatically closed and removed from the Links properties.

Config Method (AMQP Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Connect Method (AMQP Component)

This method connects to a remote host.

Syntax

void __fastcall Connect();

Remarks

This method connects to the remote host specified by RemoteHost and RemotePort. For instance: component.RemoteHost = "MyHostNameOrIP"; component.RemotePort = 7777; component.Connect();

ConnectTo Method (AMQP Component)

This method connects to a remote host.

Syntax

void __fastcall ConnectTo(String Host, int Port);

Remarks

This method connects to the remote host specified by the Host and Port parameters. For instance: component.ConnectTo("MyHostNameOrIP", 777)

CreateReceiverLink Method (AMQP Component)

Creates a new receiver link with the given name on the specified session.

Syntax

void __fastcall CreateReceiverLink(String SessionName, String Name, String Source);

Remarks

This method creates a new receiver link with the given Name on the session specified by SessionName and adds it to the Links properties. If a link (sender or receiver) with the given Name already exists, or if no session with the given SessionName exists, an error will be thrown.

Source may be set to specify the address of the node at the remote host which should act as the sender. This may not be necessary in all environments, in which case an empty string will suffice.

Receiver links can operate in one of two receive modes: automatic, where the component will work to ensure that messages are received as soon as they are available; and retrieve-based, where the component will only "retrieve" a new message when explicitly instructed to.

The ReceiveMode property controls which receive mode newly-created receiver links will use; refer to its documentation for more information.

AMQP 1.0's transport protocol has three layers: an overarching connection between two containers, the sessions opened on that connection, and the links (between the containers' nodes) attached to those sessions. amqp.ReceiveMode = AmqpReceiveModes.rmRetrieve; amqp.CreateReceiverLink("SessionID", "ReceiverLinkName", "SomeTarget");

CreateSenderLink Method (AMQP Component)

Creates a new sender link with the given name on the specified session.

Syntax

void __fastcall CreateSenderLink(String SessionName, String Name, String Target);

Remarks

This method creates a new sender link with the given Name on the session specified by SessionName and adds it to the Links properties. If a link (sender or receiver) with the given Name already exists, or if no session with the given SessionName exists, an error will be thrown.

Target may be set to specify the address of the node at the remote host which should act as the receiver. This may not be necessary in all environments, in which case an empty string will suffice.

The LinkReadyToSend event will fire when a newly-created sender link is ready to send.

Sender links are created using the Mixed settle mode by default, letting the value of the MessageSettled property control whether each message is settled (the default) or unsettled when it is sent. The DefaultSenderSettleMode configuration setting can be used to control the settle mode that new sender links are created with. Refer to SendMessage for more information on message settlement in general.

AMQP 1.0's transport protocol has three layers: an overarching connection between two containers, the sessions opened on that connection, and the links (between the containers' nodes) attached to those sessions.

CreateSession Method (AMQP Component)

Creates a new session with the given name.

Syntax

void __fastcall CreateSession(String Name);

Remarks

This method creates a new session with the given Name and adds it to the Sessions properties. If a session with the given Name already exists, an error will be thrown.

AMQP 1.0's transport protocol has three layers: an overarching connection between two containers, the sessions opened on that connection, and the links (between the containers' nodes) attached to those sessions.

Disconnect Method (AMQP Component)

This method disconnects from the remote host.

Syntax

void __fastcall Disconnect();

Remarks

This method disconnects from the remote host. Calling this method is equivalent to setting the Connected property to False.

DoEvents Method (AMQP Component)

This method processes events from the internal message queue.

Syntax

void __fastcall DoEvents();

Remarks

When DoEvents is called, the component processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Interrupt Method (AMQP Component)

This method interrupts the current action.

Syntax

void __fastcall Interrupt();

Remarks

This method interrupts the current action. If you use SendFile to upload a file, the component will run synchronously until the upload is completed. This method will allow you to stop the file from uploading without disconnecting from the host.

Reset Method (AMQP Component)

This method will reset the component.

Syntax

void __fastcall Reset();

Remarks

This method will reset the component's properties to their default values.

ResetMessage Method (AMQP Component)

Resets the Message properties.

Syntax

void __fastcall ResetMessage();

Remarks

This method resets the Message property.

RetrieveMessage Method (AMQP Component)

Retrieves a single message over the specified receiver link.

Syntax

void __fastcall RetrieveMessage(String LinkName);

Remarks

When RetrieveMessage is called, the component will supply the sender with a single credit and then block until a message is received (if the RetrieveTimeout property is set to zero).

If RetrieveTimeout is non-zero, the component will only block for the specified number of seconds; once that time expires, it will instruct the sender to consume the credit. If the sender chooses to consume the credit by incrementing the value of the LinkDeliveryCount property rather than by sending a message, then the component will throw an error indicating a timeout.

LinkName specifies the receiver link which should retrieve a message; if there is no such link, if the specified link is not a receiver link, or if the specified receiver link is not operating in rmSyncGet (1) mode, an error is thrown.

Refer to ReceiveMode and RetrieveTimeout for more information.

SendMsg Method (AMQP Component)

Sends a message on the specified link.

Syntax

void __fastcall SendMsg(String LinkName);

Remarks

Connected Event (AMQP Component)
