Package com.apple.foundationdb.record.query.plan.temp.matching

This package contains everything related to graph matching.

Interface Summary

Interface	Description
EnumerationFunction<R>	Functional interface to allow implementors to provide use case-specific logic when permutations are enumerated by BaseMatcher.match(com.apple.foundationdb.record.query.plan.temp.matching.EnumerationFunction<R>).
GenericMatcher<R>	Tag interface for generic matchers, that is instances of ComputingMatcher.
MatchAccumulator<M,R>	Class to used to accumulate the individual match results (the results of applying the MatchFunction) into an object of type R.
MatchFunction<T,M>	An functional interface for a match function that computes a match result (an Iterable of type M.
MatchPredicate<T>	An predicate that tests for a match between quantifiers also taking into account an equivalence maps between CorrelationIdentifiers.
PredicatedMatcher	Tag interface for predicate matchers, that is instances of FindingMatcher.

Class Summary

Class	Description
BaseMatcher<T>	Abstract base class for all matchers.
BoundMatch<R>	Case class to represent a match for matchers that compute a result.
ComputingMatcher<T,M,R>	This class implements a GenericMatcher which matches two sets of elements of type T to compute a result of type Iterable<BoundMatch<R>>.
FindingMatcher<T>	This class implements a PredicatedMatcher which matches two sets of elements of type T to compute an Iterable of AliasMaps.
