Method Detail

                   throws SchemaException

This method is called to look for cycles. The object implementing this method is required (a) to raise an exception if the object itself appears in the list of references, (b) to add itself to the list of references, and (c) to call the lookForCycles method on all the objects that it references.

Parameters:

references - A stack of objects that contain direct or indirect references to this object, and that must therefore not be referred to from this object.
