class Prism::HashNode

Represents a hash literal.

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

Public Class Methods

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

(Source source, Integer node_id, Location location, Integer flags, Location opening_loc, Array[AssocNode | AssocSplatNode] elements, Location closing_loc) → void

Source

# File lib/prism/node.rb, line 13961
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.

Public Instance Methods

elements → Array[AssocNode | AssocSplatNode]

() → Array[AssocNode | AssocSplatNode]

Source

# File lib/prism/node.rb, line 14095
def elements
  @elements
end

The elements of the hash. These can be either AssocNodes or AssocSplatNodes.

{ a: b }
  ^^^^

{ **foo }
  ^^^^^
