Class ADFContextVariableResolverImpl

java.lang.Object
  oracle.adf.share.el.ADFContextVariableResolverImpl

All Implemented Interfaces:

javax.servlet.jsp.el.VariableResolver

public class ADFContextVariableResolverImpl
extends java.lang.Object
implements javax.servlet.jsp.el.VariableResolver

A variable resolver that may be used against the ADFContext. This variable resolver may be used when other variable resolvers like the FacesContext variable resolver and the PageContext variable resolver are not available.

This variable resolver should not be seen as a replacement for the JSP/JSF variable resolvers. Those variable resolvers should be used whenever they are available in the container.

The ADFContextVariableResolverImpl does define an extended implicit object set for ADF. The following ADF implicit objects are supported:

securityContext -- Resolves to the current SecurityContext. Equivalent to invoking: ADFContext.getCurrent().getSecurityContext()

If you wish to use the ADF variable resolver with one of the JSP or JSF variable resolvers then you may pass the JSP/JSF variable resolver instantiate one of the resolvers that decorate this resolver.
