Method Details

apply

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

Method handles UIComponent tree creation in accordance with the Faces 1.2 spec.

1. First determines this UIComponent's id by calling DelegatingMetaTagHandler.getTagId().
2. Search the parent for an existing UIComponent of the id we just grabbed
3. If found, mark its children for deletion.
4. If not found, call createComponent.
   1. Only here do we apply MetaTagHandler.setAttributes(FaceletContext, Object)
   2. Set the UIComponent's id
   3. Set the RendererType of this instance
5. Now apply the nextHandler, passing the UIComponent we've created/found.
6. Now add the UIComponent to the passed parent
7. Lastly, if the UIComponent already existed (found), then finalize for deletion.

Specified by:

apply in class TagHandlerDelegate

Parameters:

ctx - the FaceletContext for this request

parent - the UIComponent that corresponds to this element.

Throws:

TagException - if the UIComponent parent is null

IOException - if any files necessary to apply this tag handler have any difficulty while loading

isIterating

protected boolean isIterating(FaceletContext context)

createMetaRuleset

public MetaRuleset createMetaRuleset(Class type)

Description copied from class: TagHandlerDelegate

Return a MetaRuleset particular to this kind of tag handler. Called from classes that implement MetaTagHandler.

Specified by:

createMetaRuleset in class TagHandlerDelegate

Parameters:

type - the Class for which the MetaRuleset must be created.

Returns:

a MetaRuleset particular to this kind of tag handler.
