  org.apache.myfaces.orchestra.flow.utils._ExpressionFactory

public class _ExpressionFactory
extends Object

Creates ValueExpression objects based on the "current" ELContext.

This class allows an ELContext to be "tunnelled" as a thread-local variable to places where code wants to create a ValueExpression even though the ELContext is not available as a parameter.
