org.apache.directory.api.ldap.model.subtree.SubtreeSpecificationParser

public class SubtreeSpecificationParser
extends java.lang.Object

A reusable wrapper around the antlr generated parser for an LDAP subtree specification as defined by RFC 3672. This class enables the reuse of the antlr parser/lexer pair without having to recreate the pair every time.

Parameters:

spec - the specification to be parsed

Returns:

the specification bean

Throws:

java.text.ParseException - if there are any recognition errors (bad syntax)
