Specified by:

undo in interface ICustomUndoableFeature

Parameters:

context - this is the instance of the IContext object that was in use when executing the feature

Parameters:

context - this is the instance of the IContext object that was in use when executing the feature

Returns:

true if the feature can be re-done, false if not

Since:
