Specified by:

write in interface IlvPersistentObject

Specified by:

write in interface IlvFeatureRenderer

Overrides:

write in class IlvGraphicLayerDataSource

Parameters:

stream - The stream to write to.

Throws:

IOException - thrown when an exception occurs during the write operation for this object.
