 package javax.faces.view.facelets;
 

Handles setting a javax.faces.validator.Validator instance on an javax.faces.component.EditableValueHolder parent. Will wire all attributes set to the Validator instance created/fetched. Uses the "binding" attribute for grabbing instances to apply attributes to.

Will only set/create Validator is the passed UIComponent's parent is null, signifying that it wasn't restored from an existing tree.

 
 
     private String validatorId;
     
     private TagHandlerDelegate helper;
 
     private ValidatorConfig config;


    

Construct this instance around the configuration information in argument config

Parameters:
config the TagConfig subclass for this kind of attached object.
 
     public ValidatorHandler(ValidatorConfig config) {
         super(config);
         this. = config;
         this. = config.getValidatorId();
     }

    

Return the implementation specific delegate instance that provides the bulk of the work for this handler instance.

    @Override
        if (null == ) {
             = .createValidatorHandlerDelegate(this);
        }
        return ;
    }

    

Retrieve the id of the validator that is to be created and added to the parent EditableValueHolder. All subclasses should override this method because it is important for Facelets to have a unique way of identifying the validators that are added to this EditableValueHolder and allows exclusions to work properly. An exclusion is a validator declaration that has the attribute "disabled" which resolves to false, instructing Facelets not to register a default validator with the same id.

    public String getValidatorId(FaceletContext ctx) {
        if ( == null) {
            TagAttribute idAttr = getAttribute("validatorId");
            if (idAttr == null) {
                return null;
            } else {
                return idAttr.getValue(ctx);
            }
        }
        return ;
    }


    

Return the TagConfig subclass used to configure this handler instance.

        return ;
