Detailed Description
A supertype for cursor predicate objects.
This is a super type. The state information must be stored within a subtype that makes sense to the particular dictionary implementation.
There are different types of predicates for different types of dictionary operations.
A predicate is used with the find statement to produce a dictionary instance with multiple values.
