## javax.faces.view.facelets
Class DelegatingMetaTagHandler

    java.lang.Object
      javax.faces.view.facelets.TagHandler
          javax.faces.view.facelets.MetaTagHandler
              javax.faces.view.facelets.DelegatingMetaTagHandler

All Implemented Interfaces:
  FaceletHandler

Direct Known Subclasses:
  ComponentHandler, FaceletsAttachedObjectHandler

    public abstract class DelegatingMetaTagHandler

extends MetaTagHandler

Enable the JSF implementation to provide the appropriate behavior for the kind of `MetaTagHandler` subclass for each kind of element in the view, while providing a base-class from which those wanting to make a Java language custom tag handler can inherit. The JSF runtime provides the implementation of `getTagHandlerDelegate()` for the appropriate subclass.

Field Summary
`protected TagHandlerDelegateFactory` | `delegateFactory`

Fields inherited from class javax.faces.view.facelets.TagHandler
`nextHandler, tag, tagId`

Constructor Summary
`DelegatingMetaTagHandler(TagConfig config)`

Method Summary
`void` | `apply(FaceletContext ctx, UIComponent parent)` The default implementation simply calls through to `TagHandlerDelegate.apply(javax.faces.view.facelets.FaceletContext, javax.faces.component.UIComponent)`.
`void` | `applyNextHandler(FaceletContext ctx, UIComponent c)` Invoke the `apply()` method on this instance's `TagHandler.nextHandler`.
`protected MetaRuleset` | `createMetaRuleset(Class type)` The default implementation simply calls through to `TagHandlerDelegate.createMetaRuleset(java.lang.Class)` and returns the result.
`TagAttribute` | `getBinding()`
`Tag` | `getTag()`
`TagAttribute` | `getTagAttribute(String localName)`
`protected abstract TagHandlerDelegate` | `getTagHandlerDelegate()`
`String` | `getTagId()`
`boolean` | `isDisabled(FaceletContext ctx)`
`void` | `setAttributes(FaceletContext ctx, Object instance)` Invoking/extending this method will cause the results of the created MetaRuleset to auto-wire state to the passed instance.

Methods inherited from class javax.faces.view.facelets.TagHandler

                              Object instance)

  Description copied from class: `MetaTagHandler`
  Invoking/extending this method will cause the results of the created MetaRuleset to auto-wire state to the passed instance.

  Overrides:
    `setAttributes` in class `MetaTagHandler`

### apply

    public void apply(FaceletContext ctx,
                      UIComponent parent)
               throws IOException

  The default implementation simply calls through to `TagHandlerDelegate.apply(javax.faces.view.facelets.FaceletContext, javax.faces.component.UIComponent)`.

  Parameters:
    `ctx` - the `FaceletContext` for this view execution
    `parent` - the parent `UIComponent` of the component represented by this element instance.
  Throws:
    `IOException` - if unable to load `relativePath`
  Since:
    2.0

### applyNextHandler

    public void applyNextHandler(FaceletContext ctx,
                                 UIComponent c)
                          throws IOException,
                                 FacesException,
                                 javax.el.ELException

  Invoke the `apply()` method on this instance's `TagHandler.nextHandler`.

  Parameters:
    `ctx` - the `FaceletContext` for this view execution
    `c` - the `UIComponent` of the component represented by this element instance.
  Throws:
    `IOException`
    `FacesException`
    `javax.el.ELException`
  Since:
    2.0

### createMetaRuleset

    protected MetaRuleset createMetaRuleset(Class type)

  The default implementation simply calls through to `TagHandlerDelegate.createMetaRuleset(java.lang.Class)` and returns the result.

  Specified by:
    `createMetaRuleset` in class `MetaTagHandler`
  Parameters:
    `type` - the `Class` for which the `MetaRuleset` must be created.
  Since:
    2.0
