### Public Class Methods

new(source, node_id, location, flags, elements) click to toggle source

Initialize a new `KeywordHashNode` node.

    # File prism/node.rb, line 11335
    def initialize(source, node_id, location, flags, elements)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @elements = elements
    end

type() click to toggle source

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

    # File prism/node.rb, line 11395
    def self.type
      :keyword_hash_node
    end

### 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 11401
    def ===(other)
      other.is_a?(KeywordHashNode) &&
        (flags === other.flags) &&
        (elements.length == other.elements.length) &&
        elements.zip(other.elements).all? { |left, right| left === right }
    end

accept(visitor) click to toggle source

def accept: (`Visitor` visitor) -> void

    # File prism/node.rb, line 11344
    def accept(visitor)
      visitor.visit_keyword_hash_node(self)
    end

def `child_nodes`: () -> Array[nil | Node]

    # File prism/node.rb, line 11349
    def child_nodes
      [*elements]
    end

Also aliased as: deconstruct
comment_targets() click to toggle source

def `comment_targets`: () -> Array[Node | Location]

    # File prism/node.rb, line 11359

def `compact_child_nodes`: () -> Array

    # File prism/node.rb, line 11354
    def compact_child_nodes
      [*elements]
    end

copy(node_id: self.node_id, location: self.location, flags: self.flags, elements: self.elements) click to toggle source

def copy: (?node_id: Integer, ?location: `Location`, ?flags: Integer, ?elements: Array[AssocNode | AssocSplatNode]) -> `KeywordHashNode`

    # File prism/node.rb, line 11364
    def copy(node_id: self.node_id, location: self.location, flags: self.flags, elements: self.elements)
      KeywordHashNode.new(source, node_id, location, flags, elements)
    end

deconstruct()

def deconstruct: () -> Array[nil | Node]

Alias for: child_nodes
deconstruct_keys(keys) click to toggle source

def `deconstruct_keys`: (Array keys) -> { node_id: Integer, location: `Location`, elements: Array[AssocNode | AssocSplatNode] }

    # File prism/node.rb, line 11372
    def deconstruct_keys(keys)
      { node_id: node_id, location: location, elements: elements }
    end
