Attributes
attr_reader unescaped: String
Public Class Methods
Initialize a new RegularExpressionNode
node.
# File lib/prism/node.rb, line 14987 def initialize(source, node_id, location, flags, opening_loc, content_loc, closing_loc, unescaped) @source = source @node_id = node_id @location = location @flags = flags @opening_loc = opening_loc @content_loc = content_loc @closing_loc = closing_loc @unescaped = unescaped end
Return a symbol representation of this node type. See Node::type
.

Public Instance Methods
Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
