Interface PredicateFilterSemantics

All Superinterfaces:: com.virtuosotechnologies.asaph.model.SongOperation

All Known Implementing Classes:: PredicateFilterSemantics.DefaultImplementation

public interface PredicateFilterSemantics
extends com.virtuosotechnologies.asaph.model.SongOperation

An opsemantics that runs a PredicateSemantics and filters on Boolean.TRUE. Note that this does not extend ValueFilterSemantics because it does not follow the contract of ValueFilterSemantics, which states that the values are already present in the original result set. Instead, this copies the result set, runs the given PredicateSemantics, and then filters the original result set according to the result values in the copy. Note that as a result, any values in the original resultset remain untouched.
