Interface IncrementallyUpdatedFilterPredicate

All Known Implementing Classes:

IncrementallyUpdatedFilterPredicate.And, IncrementallyUpdatedFilterPredicate.BinaryLogical, IncrementallyUpdatedFilterPredicate.DelegatingValueInspector, IncrementallyUpdatedFilterPredicate.Or, IncrementallyUpdatedFilterPredicate.ValueInspector

public interface IncrementallyUpdatedFilterPredicate

A rewritten version of a FilterPredicate which receives the values for a record's columns one by one and internally tracks whether the predicate is satisfied, unsatisfied, or unknown.

This is used to apply a predicate during record assembly, without assembling a second copy of a record, and without building a stack of update events.

IncrementallyUpdatedFilterPredicate is implemented via the visitor pattern, as is FilterPredicate
