Class LiteralLanguageTest<Node>

java.lang.Object

org.apache.marmotta.ldpath.api.tests.NodeTest<Node>

org.apache.marmotta.ldpath.model.tests.LiteralLanguageTest<Node>

All Implemented Interfaces:

NodeFunction<Boolean,Node>, LDPathConstruct<Node>

public class LiteralLanguageTest<Node>
extends NodeTest<Node>

Tests if the language of the literal node matches the language configured for the test. If the language of the test is null, only allows literal nodes without language definition.
