Class CQLCompiler

Object

CQLParser

CQLCompiler

All Implemented Interfaces:

ICompiler, CQLParserConstants, CQLParserTreeConstants

public class CQLCompiler
extends CQLParser
implements ICompiler

CQL Compiler. This class extend the CQLParser generated by javacc with semantic actions.

The "build..." methods implement that semantic actions making a filter for each syntax rules recognized.

Warning: This component is not published. It is part of module implementation. Client module should not use this feature.

TODO This module should use the new geometry API, more info in http://docs.codehaus.org/display/GEOTOOLS/GeomeryFactoryFinder+Proposal

Since:

2.5
