Overview

A temporary node used to store the value of ruby_cref or ruby_top_cref and later restore it. The cref holds a reference to the cbase, which, among other things, is used for constant and class variable lookup.

It should never be evaluated as an expression.

Class Method Summary

• .members ⇒ Array

  Return an array of strings containing the names of the node class’s members.

Instance Method Summary

• #body ⇒ Object

  Return the Node’s body member.

• #clss ⇒ Object

  Return the Node’s clss member.

• #next ⇒ Object

  Return the Node’s next member.
