unwrap

public static Object unwrap(ObjectHandler oh,
            int scopeIndex,
            Wrapper[] wrappers,
            Object[] scopes)
                     throws GuardException

Throws:

GuardException

find

public Wrapper find(String name,
           Object[] scopes)

Description copied from interface: ObjectHandler

Find a value named "name" in the array of scopes in reverse order.

Returns:

findWrapper

protected Wrapper findWrapper(int scopeIndex,
                  Wrapper[] wrappers,

name - the name in the scope

Returns:

null if not found, otherwise a wrapper for this scope and name
