Enhance the resolution of properties and methods
------------------------------------------------
Key: JEXL-28
URL: http://issues.apache.org/jira/browse/JEXL-28
Project: Commons JEXL
Issue Type: Improvement
Affects Versions: 1.1
Reporter: Weikuo Liaw
Priority: Critical
JexlContext need provide additional methods, such as
1) Object getProperty(Object object, String propName);
2) void setProperty(Object object, String propName, Object propValue);
3) Object invokeMethod(Object object, String methodName, Object[] params);
where object can be null for the non-object properties/methods.
ASTIdentifier, ASTArrayAccess, ASTAssignment, and ASTMethod can use them for
unresolvable properties/methods.
This is similar to what are changed by myFacese over commons EL to support
friendly VariableResolver and PropertyResolver for applications.
I use "ObjectinvokeMethod()" instead of "Method getMethod(object, methodNae)",
because a method may not be implemented as a java method. Such as in commons
validator, validators are registered in the configuration file of validation
forms.
