PipeServer Component

Properties   Methods   Events   Configuration Settings   Errors  

The PipeServer component is a lightweight server component based on an asynchronous, event-driven architecture. It is designed to balance the load between connections for a fast, powerful server.

Syntax

TiipPipeServer

Remarks

PipeServer is the server complement of PipeClient (which is used to create client applications). They share a common design philosophy and interface. PipeServer is as easy to use as PipeClient.

The client connections are identified by a ConnectionId, an id generated by the component to identify each connection. This id is unique to each connection. PipeServer's events also have ConnectionId as a parameter to identify the connection to which they are related.

Our main goal in designing PipeServer was to make it easy to use without sacrificing performance. The component has a minimum of properties, and events: Connected, DataIn, Disconnected, ReadyToSend, and Error.

PipeServer can start to listen on a pipe by setting PipeName and then setting Listening to True. When a client connects the Connected event fires, a ConnectionId is assigned, and communication can start. From this point on, the operation is very similar to PipeClient. Data is sent by assigning the data string to the DataToSend property.

Property List


The following is the full list of the properties of the component with short descriptions. Click on the links for further details.

ConnectionCountThe number of records in the arrays.
AcceptDataSetting this property to False, temporarily disables data reception (and the DataIn event) on the connection.
BytesSentThis property shows how many bytes were sent after the last assignment to DataToSend .
ConnectedThis property is used to disconnect individual connections and/or show their status.
ConnectionIdThis property contains an identifier generated by the component to identify each connection.
DataToSendThis property contains a string of data to be sent to the remote host.
EOLThe EOL property is used to define boundaries in the input stream using the value of the property.
MaxLineLengthThis property is the size of an internal buffer which holds received data while waiting for an EOL string.
SingleLineModeThis property shows the special mode for line-oriented protocols.
TimeoutThis property specifies a timeout for the component.
DefaultEOLA default EOL value to be used by incoming connections.
DefaultMaxLineLengthThe default maximum line length value for inbound connections.
DefaultSingleLineModeTells the component whether or not to treat new connections as line-oriented.
DefaultTimeoutAn initial timeout value to be used by incoming connections.
ListeningIf True, the component accepts incoming connections.
PipeNameThe name of the pipe.
