public boolean isSupportedAtVersion(int docVersion)
                             throws IOException,
                                    AutomationException

Is this object valid at the given document version.

Remarks

Use IsSupportedAtVersion to identify if a particular object should be saved to the ObjectStream. This result is based on the esriArcGISVersion enumeration. In some instances, if the object is not supported at a particular ArcGIS version, the object may support conversion to another similar object; use IDocumentVersionSupportGEN::ConvertToSupportedObject to accomplish this.

Product Availability

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

Specified by:

isSupportedAtVersion in interface IDocumentVersionSupportGEN

Parameters:

docVersion - A com.esri.arcgis.system.esriArcGISVersion constant (in)

Returns:

The supported

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

convertToSupportedObject

public Object convertToSupportedObject(int docVersion)
                                throws IOException,
                                       AutomationException

Convert the object to another object that is supported.

Remarks

This method should be used when IDocumentVersionSupportGEN::IsSupportedAtVersion returns FALSE. Calling ConvertToSupportedObject will return an IUnknown pointer to a relevant object supported at the particular ArcGIS version. Not all objects will return a supported object; in these cases a null pointer will be returned.
