OData Class

Properties   Methods   Events   Config Settings   Errors  

The OData class implements the Open Data Protocol (OData). It can be used to query, parse, and update or modify data contained within an OData service.

Syntax

ipworks.odata()

Remarks

The OData Class supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over Secure Sockets Layer/Transport Layer Security (SSL/TLS) the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL-related settings are also supported through the Config method.

The OData component allows you to easily query OData services and create, update, and delete entries within a service. To query a service, you can set the ServiceRootURI to the service's root URI and ResourcePath to the collection within the service that you wish to query. Optionally you can set the Query*** properties to filter the results. QueryService can then be called to retrieve the results (which can be viewed via the Entry*** properties).

Example 1. Query a Service: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.ResourcePath = "Products" OData1.QueryService()

To create a new entry, you can set the ServiceRootURI to the service's root URI and ResourcePath to the collection within the service that you wish to add the entry to. The Entry*** properties can be set to the values you wish to use to create the entry. CreateEntry can then be called to create the entry.

Example 2. Create a New Entry: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.ResourcePath = "Products" OData1.EntryProperties OData1.CreateEntry()

If you wish to update an entry, you can set the ServiceRootURI to the service's root URI and ResourcePath to the specific entry you wish to update. The Entry*** properties can be set to the values you wish to update. UpdateEntry can then be called to update the entry.

Example 3. Update an Entry: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.ResourcePath = "Products(1)" // Index 1 is the "Name" property. OData1.EntryProperties[1].Value = "MyNewName" OData1.UpdateEntry()

Deleting an entry requires that you first set the ServiceRootURI to the service's root URI and ResourcePath to the specific entry you wish to delete. DeleteEntry can then be called to delete the entry.

Example 4. Delete an Entry: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.ResourcePath = "Products(1)" OData1.DeleteEntry()

In addition to querying a service and manipulating its containing data, the OData component also allows you to retrieve the schema (metadata document) to determine the structure of a service. After setting ServiceRootURI to the root URI of the service, GetSchema can be called to retrieve the metadata document. The Schema*** properties will be populated upon successful retrieval of the metadata document allowing you to identify the structure of the service.

Example 5. Retrieve the Scheme: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.GetSchema()

OData.Authorization Property

This property includes the Authorization string to be sent to the server.

Syntax

getAuthorization(): string;
setAuthorization(authorization: string): void;

Default Value

""

Remarks

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

A common use for this property is to specify OAuth authorization string.

This property is provided so that the HTTP class can be extended with other security schemes in addition to the authorization schemes already implemented by the class.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

OData.AuthScheme Property

This property specifies the authentication scheme to use when server authentication is required.

Syntax

getAuthScheme(): ODataAuthSchemes;
setAuthScheme(authScheme: ODataAuthSchemes): void;

enum ODataAuthSchemes {
  authBasic,
  authDigest,
  authProprietary,
  authNone,
  authNtlm,
  authNegotiate,
  authOAuth
}

Default Value

0

Remarks

This property will tell the class which type of authorization to perform when the User and Password properties are set.

This property should be set to authNone (3) when no authentication is to be performed.

By default, this property is authBasic (0), and if the User and Password properties are set, the class will attempt HTTP Basic Authentication. If AuthScheme is set to authDigest (1), authNtlm (4), or authNegotiate (5), then Digest, NTLM, or Windows Negotiate (Kerberos) authentication will be attempted instead.

If AuthScheme is set to authProprietary (2), then the authorization token must be supplied through the Authorization property.

If AuthScheme is set to authOAuth (6), then the authorization string must be supplied through the Authorization property.

Note: If you set the Authorization property and AuthScheme is not authProprietary or authOAuth, then the AuthScheme will be set automatically to authProprietary (2) by the class.

For security, changing the value of this property will cause the class to clear the values of User, Password, and Authorization.

OData.Channel Property

This includes the feed elements of a feed.

OData.config Method

Sets or retrieves a configuration setting.

Syntax

async odata.config(configurationString : string): Promise<string>

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, 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.

OData.createEntry Method

This method creates a new entry within the specified OData service resource.

Syntax

async odata.createEntry(): Promise<void>

Remarks

The component will use the items contained within EntryProperties to create a new entry within the feed service resource by ServiceRootURI and ResourcePath (ServiceRootURI/ResourcePath).

Upon a successful creation, all previous entries contained by the component, before the CreateEntry call, will be cleared and replaced with the response entry data. EntryIndex will then be set to 0 (the first entry within the response), populating the EntryAuthor, EntryETag, EntryTitle, EntrySummary, EntryUpdated, EntryLinks, and EntryProperties properties. OtherHeaders will also be cleared and thus will need to be reset accordingly with each call made.

OData.customRequest Method

This method sends a request to the specified URL using the HTTPMethod and PostData provided.

Syntax

async odata.customRequest(HTTPMethod : string, URL : string, postData : string): Promise<void>

Remarks

This method sends a custom request to the specified URL. The type of request sent is determined by HTTPMethod (e.g., POST) and the data sent are determined by PostData. If a custom request does not require data to be sent, simply set the PostData parameter to an empty string.

Note: All values specified are taken as entered.

OtherHeaders can be used to specify any additional headers you would like to be sent in the custom request.

The search results are delivered in the TransferredData property, as well as through the Transfer event. The response headers can be retrieved through the TransferredHeaders property as well as through the Header event.

The class will then attempt to parse the search results. Upon successfully parsing the response, Channel will be set with their associated feed element values and EntryCount will be populated with the total number of entries contained within the feed. EntryIndex also will be set to 1, thus populating EntryProperties.

OData.deleteEntry Method

This method deletes an entry within an OData service resource.

Syntax

async odata.deleteEntry(): Promise<void>

Remarks

The component will delete the entry, of an OData service resource, specified by ServiceRootURI and ResourcePath (ServiceRootURI/ResourcePath).

An "If-Match" header will be sent in the delete request with the value contained within EntryETag.

Upon a successful entry deletion, all previous entries contained by the component, before the DeleteEntry call, will be cleared. OtherHeaders also will be cleared and thus will need to be reset accordingly with each call made.

OData.getEntryProperty Method

This method gets an OData entry property.

Syntax

async odata.getEntryProperty(XPath : string): Promise<string>

Remarks

This method is intended to extend the functionality of the OData class and will retrieve the value of the entry property specified by XPath. XPath is the XPath of the element or attribute according to the following convention: entry[x]/element@attribute. The @attribute part is optional. When EntryIndex is set to an index greater than or equal to zero, a relative path also can be used: property or property@attribute. When a relative path is specified, the value of the specified XPath will be returned for the entry identified by EntryIndex.

entry[x] is the feed's xth entry (or any other root-level child), where the indexer x starts at 1.

property is any child of the property's element, and attribute can be any attribute of that field. If an attribute is not supplied, the GetEntryProperty method will return the text portion of property.

Example 1. Attribute Not Supplied: ODataControl.GetEntryProperty("entry[5]/content/properties/ID") ODataControl.GetEntryProperty("entry[5]/content/properties/ID@type")

Example 2. Relative Path: In the following example, a relative path is used to retrieve properties of the first feed entry: ODataControl.EntryIndex = 1 ODataControl.GetEntryProperty("ID") ODataControl.GetEntryProperty("ID@type") ODataControl.GetEntryProperty("Address/State")

OData.getSchema Method

This method retrieves the schema for a service.

Syntax

Additional details about the schema can be retrieved via XPath.

OData.hasXPath Method

This method determines whether a specific element exists in the document.

Syntax

async odata.hasXPath(XPath : string): Promise<boolean>

Remarks

This method determines whether a particular XPath exists within the document. This may be used to check if a path exists before setting it through XPath.

This method returns True if the xpath exists, and False if not.

See XPath for details on the XPath syntax.

OData.queryService Method

This method queries an OData service using the specified parameters.

Syntax

async odata.queryService(): Promise<void>

Remarks

This method queries an OData feed specified by ServiceRootURI and ResourcePath (ServiceRootURI/ResourcePath) using the query options specified in the Query*** properties and OtherQueryOptions. To retrieve an OData feed, without performing any filtering, you can leave Query*** and OtherQueryOptions empty and call QueryService.

The query results are delivered in the TransferredData property, as well as through the Transfer event. The response headers can be retrieved through the ParsedHeaders property as well as through the Header event.

The class will attempt to parse the query results. Upon successfully parsing the response, Channel will be set with their associated feed element values and EntryCount will be populated with the total number of entries contained within the feed. EntryIndex will also be set to 1, thus populating EntryAuthor, EntryETag, EntryTitle, EntrySummary, EntryUpdated, EntryLinks, EntryProperties, and ResourcePath.

OData.reset Method

This method resets all of properties of the class.

Syntax

async odata.reset(): Promise<void>

Remarks

OData.setEntryProperty Method

This method is used to set an OData entry property.

Syntax

async odata.setEntryProperty(XPath : string, value : string): Promise<void>

Remarks

This method is intended to extend functionality of the OData class and will set the value of the entry property (specified by XPath) to the specified Value. Therefore, the value of the corresponding property will be updated within EntryProperties.

XPath is the XPath of the element or attribute according to the following convention: entry[x]/element. When EntryIndex is set to an index greater than or equal to zero, a relative path can also be used: property. When a relative path is specified, the class will use the specified EntryIndex along with the property specified to update the EntryProperty value.

entry[x] is the feed's xth entry (or any other root-level child), where the indexer x starts at 1.

property is any child of the property's element.

Example 1. Set Properties: ODataControl.SetEntryProperty("entry[5]/content/properties/Name", "MyNewName") Example 2. Retrieve Properties:

The following example uses a relative path to retrieve properties of the first feed entry: ODataControl.EntryIndex = 1 ODataControl.SetEntryProperty("Name", "MyNewName") ODataControl.SetEntryProperty("Address/State", "NC")
