class Prism::AssocNode

Represents a hash key/value pair.

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

Attributes

key[R]

The key of the association. This can be any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

{ a: b }
  ^

{ foo => bar }
  ^^^

{ def a; end => 1 }
  ^^^^^^^^^^

value[R]

The value of the association, if present. This can be any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

{ foo => bar }
         ^^^

{ x: 1 }
     ^

Public Class Methods

new(source, node_id, location, flags, key, value, operator_loc) click to toggle source

Initialize a new AssocNode node.

# File lib/prism/node.rb, line 969
def initialize(source, node_id, location, flags, key, value, operator_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @key = key
  @value = value
  @operator_loc = operator_loc
end

type() click to toggle source

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

# File lib/prism/node.rb, line 1063
def self.type
  :assoc_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 lib/prism/node.rb, line 1069
def ===(other)
  other.is_a?(AssocNode) &&
    (key === other.key) &&
    (value === other.value) &&
    (operator_loc.nil? == other.operator_loc.nil?)
end

accept(visitor) click to toggle source

def accept: (Visitor visitor) -> void

# File lib/prism/node.rb, line 980
def accept(visitor)
  visitor.visit_assoc_node(self)
end

child_nodes() click to toggle source

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

# File lib/prism/node.rb, line 985
def child_nodes
  [key, value]
end

Also aliased as: deconstruct

comment_targets() click to toggle source

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

# File lib/prism/node.rb, line 995
def comment_targets
  [key, value, *operator_loc] #: Array[Prism::node | Location]
end

compact_child_nodes() click to toggle source

def compact_child_nodes: () -> Array

# File lib/prism/node.rb, line 990
def compact_child_nodes
  [key, value]
end

copy(node_id: self.node_id, location: self.location, flags: self.flags, key: self.key, value: self.value, operator_loc: self.operator_loc) click to toggle source

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?key: Prism::node, ?value: Prism::node, ?operator_loc: Location?) -> AssocNode

# File lib/prism/node.rb, line 1000
def copy(node_id: self.node_id, location: self.location, flags: self.flags, key: self.key, value: self.value, operator_loc: self.operator_loc)
  AssocNode.new(source, node_id, location, flags, key, value, operator_loc)
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, key: Prism::node, value: Prism::node, operator_loc: Location? }

# File lib/prism/node.rb, line 1008
def deconstruct_keys(keys)
  { node_id: node_id, location: location, key: key, value: value, operator_loc: operator_loc }
end

inspect() click to toggle source

def inspect -> String

# File lib/prism/node.rb, line 1053
def inspect
  InspectVisitor.compose(self)
end

operator() click to toggle source

def operator: () -> String?

# File lib/prism/node.rb, line 1048
def operator
  operator_loc&.slice
end

operator_loc() click to toggle source

The location of the ‘=>` operator, if present.

{ foo => bar }
      ^^

# File lib/prism/node.rb, line 1035
def operator_loc
  location = @operator_loc
  case location
  when nil
    nil
  when Location
    location
  else
    @operator_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
  end
end

type() click to toggle source

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