class Prism::HashNode
Represents a hash literal.
{ a => b } ^^^^^^^^^^
Attributes
The elements of the hash. These can be either ‘AssocNode`s or `AssocSplatNode`s.
{ a: b } ^^^^ { **foo } ^^^^^
Public Class Methods
Initialize a new HashNode
node.
# File lib/prism/node.rb, line 7204 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
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.
# File lib/prism/node.rb, line 7303 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
