.An
AnyType
is additionally anAssociationType
; so if this method returns true, thenType.isAssociationType()

isAnyType
in classAbstractType

- True if this type is also an
AnyType
implementor; false otherwise.

- True if this type is also an
AssociationType
implementor; false otherwise.

Return true if the implementation is castable toCompositeType
. Shortcut fortype instanceof CompositeType
.A component type may own collections or associations and hence must provide certain extra functionality.
- Specified by:
isComponentType

CompositeType
implementor; false otherwise.
