java.lang.Object
org.apache.myfaces.view.facelets.TemplateContext
- Direct Known Subclasses:
TemplateContextImpl
This class is used to encapsulate the information required to resolve
facelets templates.
Composite components require to "isolate" the inner template resolution.
That means, when a ui:xx tag is used, do not take into account the outer
templates defined.
The methods here are only used by the current implementation and the intention
is not expose it as public api.
