Direct Known Subclasses:

SetTagHandler

public class AliasTagHandler
extends javax.faces.view.facelets.ComponentHandler

Tag handler that exposes variables to the variable map. Behaviour is close to the c:set tag handler except:

• It handles several variables
• It allows caching a variable using cache parameter: variable will be resolved the first time is is called and will be put in the context after
• The resolved variable is removed from context when tag is closed to avoid filling the context with it
• Variables are made available in the request context after the JSF component tree build thanks to a backing component.

The backing component value expressions are changed even if the component was found to ensure a good resolution even when re-rendering the tag using ajax.
