javax.el.ELResolver

org.eclnt.jsfserver.util.CCELResolver

public class CCELResolver
extends javax.el.ELResolver

This class wraps the default expression resolver in order to wrap the getting/setting functions with some additional functions.

(1.) Interface IPropertyTypeResolver during getType(..) call.
(2.) Interface IAcceleratedPropertyAccess during getValue(..) call.
(3.) Hot Deployment Management.
(4.) Possibility to (re-) set a managed bean at runtime.
(5.) Before setting property values the interface IPropertyValueConverter is called, if available.


The functions of this class were part of the CaptainCasa-specific variable and property resolver with JSF 1.1 - due to changed from JSF 1.1 to JSF 1.2 they were shifted into this class...

Constructor Details

CCELResolver

public CCELResolver(javax.el.ELResolver delegateTo)

Default constructor to be used in normal Servelt/JSF environment.

CCELResolver

public CCELResolver()

Sepcial constructor to be used in mini server environment. In this scenario there is no delegation possibility. And in this scenario all expressions need to be resolved through the CCELResolver (i.e. there is NO resolution of e.g. "d" by the resolver of the servlet/JSF environment.

unregisterThreadWithErrorFalse

public static void unregisterThreadWithErrorFalse()

checkIfThreandWithErrorFalse

public static boolean checkIfThreandWithErrorFalse()

resetBuffers

public static void resetBuffers()
