                                        java.lang.Object base,

                                 throws XelException

Description copied from interface: VariableResolverX

Resolves the the given variable on the given base object.

It resolves not only top-level variables but also properties. For example, when resolving foo.duke, resolveVariable(ctx, null, "foo") is called first. And if it returns an non-null object, resolveVariable(ctx, foo, "duke"),/code> is called then (where we assume the returned object in the previous call is foo).

Specified by:

resolveVariable in interface VariableResolverX

Parameters:

ctx - the context of this evaluation

base - the base object whose property value is to be returned, or null to resolve a top-level variable.

name - the name of the variable (or property) to resolve

Throws:

XelException
