Class TargetElements

java.lang.Object

com.exsoinn.util.ForwardingImmutableSet<String>

com.exsoinn.util.epf.TargetElements

All Implemented Interfaces:

Iterable<String>, Collection<String>, Set<String>

@Immutable
public final class TargetElements
extends ForwardingImmutableSet<String>

Encapsulates a set of elements to return from a Context search. As a performance optimization, instances of this class are cached based on the order of the elements in the set. This means that sets "elem1,elem2" and "elem2,elem1" will be treated as two distinct objects, even though it's the same set. We figured that if we sorted the set elements every time an instance of this class is requested, it might result in a performance penalty, which defeats the purpose of caching in the first place. Having a few duplicate elements here and there is better as opposed to having to sort on every invocation. Objects of this class are made unmodifiable by having this class extend ForwardingImmutableSet. Created by QuijadaJ on 5/3/2017.
