Examples of javax.faces.el.PropertyResolver

javax.faces.el.PropertyResolver

PropertyResolver represents a pluggable mechanism for accessing a "property" of an underlying Java object instance. Different {@link PropertyResolver} implementations can supportproperty resolution on instances of different Java classes (such as introspection-based access to properties of a JavaBeans component, or get() and put() calls on a java.util.Map instance).

All implementations must respect the rules for JavaBeans component, java.util.Map, java.util.List and array instances defined for each method but are allowed to add custom semantics for other types.
@deprecated This has been replaced by {@link javax.el.ELResolver}.

        for (int i = 1; i < names.size() - 1; i++) {
            base = pr.getValue(base, (String) names.get(i));
        }


        // Return the type of the final property
        return pr.getType(base, (String) names.get(names.size() - 1));
