Class InternedIRI

java.lang.Object

org.da.sparqlhelper.sparql.parser.vocabulary.InternedIRI

All Implemented Interfaces:

IRI

public final class InternedIRI
extends java.lang.Object
implements IRI

An IRI implementation that interns the stringValue so that two objects can be compared by their stringValue reference. Must only be used for IRIs that are effectively ´public static final´ and only for a very limited number of objects because string interning affects the GC root set (https://shipilev.net/jvm/anatomy-quarks/10-string-intern/).
