public interface IDataLayer
extends Serializable

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

Superseded By

IDataLayer2

Remarks

This interface provides access to information about the data source of the layer including: the data source name, the base path used in relative pathnames, and whether the layer supports the data source. There is also a method to connect to the data source if the connection has been lost.

Product Availability

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

Method Summary

boolean	connect(IName pOptRepairName) Connects the layer to its data source.
IName	getDataSourceName() Name of the data object for the layer.
String	getRelativeBase() Base path used when storing relative path names.
boolean	isDataSourceSupported(IName name) Indicates if the specified data object name is supported by the layer.
void	setDataSourceName(IName name) Name of the data object for the layer.
void	setRelativeBase(String basePath) Base path used when storing relative path names.

Method Detail

getDataSourceName

IName getDataSourceName()
                        throws IOException,
                               AutomationException

Name of the data object for the layer.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:

A reference to a com.esri.arcgis.system.IName

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setDataSourceName

void setDataSourceName(IName name)
                       throws IOException,
                              AutomationException

Name of the data object for the layer.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Parameters:

name - A reference to a com.esri.arcgis.system.IName (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isDataSourceSupported

boolean isDataSourceSupported(IName name)
                              throws IOException,
                                     AutomationException

Indicates if the specified data object name is supported by the layer.

Product Availability

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

Parameters:

name - A reference to a com.esri.arcgis.system.IName (in)

Returns:

The supported

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

connect

boolean connect(IName pOptRepairName)
                throws IOException,
                       AutomationException

Connects the layer to its data source. An optional name object can be specified to aid in repairing a lost connection.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Parameters:

pOptRepairName - A reference to a com.esri.arcgis.system.IName (in)

Returns:

The succeeded

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getRelativeBase

String getRelativeBase()
                       throws IOException,
                              AutomationException

Base path used when storing relative path names.

Remarks

The RelativeBase property is used internally when persisting and loading documents with a relative path. When a document has been fully loaded the path is realized to a complete path.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:

The basePath

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setRelativeBase

void setRelativeBase(String basePath)
                     throws IOException,
                            AutomationException

Base path used when storing relative path names.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Parameters:

basePath - The basePath (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
