Parameters

[out] or Return Value
True if the dictionary is released and erased, false if not (see Remarks)

Remarks

If the dictionary exists and is not empty, i.e., it contains one or more XRecords, then it is not released and erased. You must remove or erase all XRecords from the dictionary before you can release and erase the dictionary. See IDictionary::RemoveEntry and IXRecord::Erased.

To restore a released and erased dictionary for this DGN definition, call IImageDefinition::CreateExtensionDictionary or IDictionary::Erased. If you close the drawing before restoring the released and erased dictionary, then that dictionary is deleted from the drawing and cannot be restored.

This method also returns true if the dictionary does not exist.
