Member Function Documentation

sequence<byte> getImplementationId ( )

Obsolete unique identifier.

Originally returned a sequence of bytes which, when non-empty, was used as an ID to distinguish unambiguously between two sets of types, for example to realise hashing functionality when the object is introspected. Two objects that returned the same non-empty ID had to return the same set of types in getTypes(). (If a unique ID could not be provided, this method was always allowed to return an empty sequence, though).

Deprecated:
This feature should no longer be used, and implementations are encouraged to always return an empty sequence.
sequence<type> getTypes ( )

returns a sequence of all types (usually interface types) provided by the object.

Attention
If the object aggregates other objects the sequence also has to contain all types supported by the aggregated objects.
