 * The NewFilterClassOperation is an IDataModelOperation following the
 * IDataModel wizard and operation framework.
 * 
 * @see org.eclipse.wst.common.frameworks.datamodel.IDataModelOperation
 * @see org.eclipse.wst.common.frameworks.datamodel.IDataModelProvider
 * 
 * It extends ArtifactEditProviderOperation to provide filter specific java
 * class generation.
 * @see org.eclipse.wst.common.componentcore.internal.operation.ArtifactEditProviderOperation
 * 
 * This operation is used by the AddFilterOperation to generate an
 * non annotated java class for an added filter. It shares the
 * NewFilterClassDataModelProvider with the AddFilterOperation to store the
 * appropriate properties required to generate the new filter.
 * @see org.eclipse.jst.j2ee.internal.web.operations.AddFilterOperation
 * @see org.eclipse.jst.j2ee.internal.web.operations.NewFilterClassDataModelProvider
 * 
 * A WTPJetEmitter filter template is used to create the class with the filter template. 
 * @see org.eclipse.jst.j2ee.internal.project.WTPJETEmitter
 * @see org.eclipse.jst.j2ee.internal.web.operations.CreateFilterTemplateModel
 * 
 * Subclasses may extend this operation to provide their own specific filter
 * java class generation. The execute method may be extended to do so. Also,
 * generateUsingTemplates is exposed.
