Class OpenL

java.lang.Object

org.openl.OpenL

public class OpenL
extends Object

This class describes OpenL engine context abstraction that used during compilation process.

The class OpenL implements both factory(static) methods for creating OpenL instances and actual OpenL functionality. Each instance of OpenL should be considered as a Language Configuration(LC). You may have as many LCs in your application as you want. Current OpenL architecture allows to have different OpenL configurations in separate class loaders, so they will not interfere with each other. It allows, for example, to have 2 LCs using different SAX or DOM parser implementation.

The actual work is done by class OpenLConfigurator.

                                IOpenLBuilder builder)

Gets an instance of OpenL. Each instance is cached with name and user context as it's key.

Parameters:

name - IOpenL name

userContext - user context

builder - IOpenLBuilder instance which used to build new instance of OpenL if that does not exist

Returns:

instance of IOpenL

Throws:

OpenLConfigurationException
