      • setSelf

        public void setSelf​(java.lang.Object self)
        Sets the self variable. The self variable also acts as the context to resolve other variables.
      • getSelf

        public java.lang.Object getSelf()
        Returns the self variable.
      • resolveVariable

        public java.lang.Object resolveVariable​(XelContext ctx,
                                                java.lang.Object base,
                                                java.lang.Object onm)
        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") is called then (where we assume the returned object in the previous call is foo).

        Specified by:
        resolveVariable in interface VariableResolverX
        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.
        onm - the name of the variable (or property) to resolve
