           Summary: [JEXL] Static method resolution and changes to context
           Product: Commons
           Version: 1.0 Final
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: JEXL
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: dion@apache.org


From: Guido Anzuoni <ganzuoni@gmail.com>

Here I will try to explain may changes to see if you agree to include in the trunk.
1. UberspectImpl
I need to include static methods resolution in expressions (e.g.
System.currentTimeMillis()). I patched the class to allow it.

2. JexlContext
Resolving vars using a Map is not enough flexible for my needs. I have modified
it to have a single method
public Object resolveVariable(String var);

This allows me for better flexibility in the resolution process.
I have implemented a JextContext based on a java.util.Map, an extensible
JexlContext and a delegating JexlContext.
The extensible resolver is abstract and has a "parent" context to which
delegates in the case local resolution failes.
Delegating implementation extends the extensible context and uses another
JexlContext for local resolution.

More, I have removed any reference to JexlContex.getVars() in the code.

If you wish I can send the modified classes to better evaluate my changes.
