Overview

Represents a regular expresion with interpolation. The node is evaluated by duplicating the regex stored in the ‘lit’ element, then iterating over the nodes stored in the ‘next’ element. Each node found should evaluate to a string, and each resulting string is appended onto the original string. Interpolation is represented with the EVSTR node.

Instance Method Summary

• #cflag ⇒ Object

  Return the Node’s cflag member.

• #lit ⇒ Object
