ElementCategoryFilter

Description:
A filter used to match elements by their category.
Remarks:
This filter is a quick filter. Quick filters operate only on the ElementRecord, a low-memory class which has a limited interface to read element properties. Elements which are rejected by a quick filter will not be expanded in memory.
