IDataLayer2 Interface

Provides access to additional members that control the data source properties of a layer.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Members

	Name	Description
	Connect	Connects the layer to its data source. An optional name object can be specified to aid in repairing a lost connection.
	DataSourceName	Name of the data object for the layer.
	DataSourceSupported	Indicates if the specified data object name is supported by the layer.
	Disconnect	Disconnects the data from the layer.
	InWorkspace	Returns TRUE if the layer is in the specified workspace.
	RelativeBase	Base path used when storing relative path names.

Remarks

This interface provides access to all of the methods and properties of IDataLayer and also two additional methods. Disconnect disconnects a layer from its data source. Given a workspace, InWorkspace returns a boolean indicating whether or not the layer's data source is in the workspace.
