Imports

javax.el.ELContext, .ELResolver, .FunctionMapper, .ValueExpression, .VariableMapper, java.util.Map, .HashMap, java.lang.reflect.Method

Concrete implementation of javax.el.ELContext. ELContext's constructor is protected to control creation of ELContext objects through their appropriate factory methods. This version of ELContext forces construction through FacesContextImpl.

getELResolver back to summary

getELResolver	back to summary
public ELResolver getELResolver() Implements abstract javax.el.ELContext.getELResolver. Doc from javax.el.ELContext.getELResolver. Retrieves the `ELResolver` associated with this context. The `ELContext` maintains a reference to the `ELResolver` that will be consulted to resolve variables and properties during an expression evaluation. This method retrieves the reference to the resolver. Once an `ELContext` is constructed, the reference to the `ELResolver` associated with the context cannot be changed. Returns:ELResolver The resolver to be consulted for variable and property resolution during expression evaluation. Annotations @Override

public ELResolver getELResolver()

Implements abstract javax.el.ELContext.getELResolver.
