Method Detail

doesRespondTo

public boolean doesRespondTo(com.oracle.truffle.api.frame.VirtualFrame frame,
                    Object methodName,
                    Object receiverObject)

Check if a specific method is defined on the receiver object. This check is "static" and should only be used in a few VM operations. In many cases, a dynamic call to Ruby's respond_to? should be used instead. Similar to MRI rb_check_funcall().
