class Prism::HashNode

Represents a hash literal.

{ a => b }
^^^^^^^^^^

Attributes

elements [R]

The elements of the hash. These can be either ‘AssocNode`s or `AssocSplatNode`s.

{ a: b }
  ^^^^

{ **foo }
  ^^^^^

Public Class Methods

new (source, node_id, location, flags, opening_loc, elements, closing_loc)

Source

# File lib/prism/node.rb, line 7914
def initialize(source, node_id, location, flags, opening_loc, elements, closing_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @opening_loc = opening_loc
  @elements = elements
  @closing_loc = closing_loc
end

Initialize a new HashNode node.

type ()

Source

# File lib/prism/node.rb, line 8019
def self.type
  :hash_node
end

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

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 8025
def ===(other)
  other.is_a?(HashNode) &&
    (opening_loc.nil? == other.opening_loc.nil?) &&
    (elements.length == other.elements.length) &&
    elements.zip(other.elements).all? { |left, right| left === right } &&
    (closing_loc.nil? == other.closing_loc.nil?)
end

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