resolveVariable

public java.lang.Object resolveVariable(XelContext ctx,
                                        java.lang.Object base,
                                        java.lang.Object name)
                                 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
