java.lang.Object

org.apache.directory.api.ldap.trigger.TriggerSpecificationParser

public class TriggerSpecificationParser
extends java.lang.Object

A reusable wrapper around the ANTLR generated parser for a TriggerSpecification. This class enables the reuse of the antlr parser/lexer pair without having to recreate them every time.
