Class FacesELResolver

java.lang.Object

javax.el.ELResolver

org.omnifaces.el.FacesELResolver

public class FacesELResolver
extends ELResolver

This EL resolver basically creates an implicit object #{faces} in EL scope.

All methods of Faces utility class which start with "get" or "is", and take no parameters, and return either String or boolean, and are not related to response nor to session or flash (for which already implicit EL objects #{session} and #{flash} exist), will be available as properties of the implicit object #{faces}. Examples are:

 #{faces.development}
 #{faces.serverInfo}
 #{faces.ajaxRequest}
 #{faces.requestBaseURL}
 #{faces.requestURLWithQueryString}
