Public Class Methods

new(source, node_id, location, flags, pattern, statements, in_loc, then_loc) click to toggle source

Initialize a new InNode node.

# File lib/prism/node.rb, line 8629
def initialize(source, node_id, location, flags, pattern, statements, in_loc, then_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @pattern = pattern
  @statements = statements
  @in_loc = in_loc
  @then_loc = then_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 lib/prism/node.rb, line 8741
def ===(other)
  other.is_a?(InNode) &&
    (pattern === other.pattern) &&
    (statements === other.statements) &&
    (in_loc.nil? == other.in_loc.nil?) &&
    (then_loc.nil? == other.then_loc.nil?)
end
