Public Class Methods

new(source, node_id, location, flags, opening_loc, parts, closing_loc) click to toggle source

Initialize a new InterpolatedMatchLastLineNode node.

# File prism/node.rb, line 9355
def initialize(source, node_id, location, flags, opening_loc, parts, closing_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @opening_loc = opening_loc
  @parts = parts
  @closing_loc = closing_loc
end

type() click to toggle source

Return a symbol representation of this node type. See ‘Node::type`.

Public Instance Methods

===(other) click to toggle source

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

# File prism/node.rb, line 9497
def ===(other)
  other.is_a?(InterpolatedMatchLastLineNode) &&
    (flags === other.flags) &&
    (opening_loc.nil? == other.opening_loc.nil?) &&
    (parts.length == other.parts.length) &&
    parts.zip(other.parts).all? { |left, right| left === right } &&
    (closing_loc.nil? == other.closing_loc.nil?)
