Interface EquivalenceComparatorChain<E,C>

Type Parameters:

E - the type of the elements in the set

C - the type of the context the element is compared against, e.g. a Graph

All Superinterfaces:

EquivalenceComparator<E,C>

All Known Implementing Classes:

EquivalenceComparatorChainBase

public interface EquivalenceComparatorChain<E,C>
extends EquivalenceComparator<E,C>

A container of comparators, which are tested in a chain until the first result can be supplied. It implements the EquivalenceComparator, so chains can include other chains. The first check will use the current comparator and not the next one. So, make sure to use the one which has better performance first. (This class follows the "Composite" design-pattern).

Method Detail

appendComparator

void appendComparator(EquivalenceComparator<E,C> comparatorAfter)

Adds a comparator which will also test equivalence. For equivalenceCompare(), the return value is a logical AND of the two comparators. The first check will use the first comparator before the next one. Make sure to put the one which has better performance first. For equivalenceHashcode(), the resulting hashes will be rehashed together. This method may be used multiple times to create a long "chain" of comparators.
