Represents a hash key/value pair.

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

Public Class Methods

new (source, node_id, location, flags, key, value, operator_loc)

Source

# File lib/prism/node.rb, line 1517
def initialize(source, node_id, location, flags, key, value, operator_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @key = key

  @operator_loc = operator_loc
end

Initialize a new AssocNode node.

Public Instance Methods

key → Node

Source

# File lib/prism/node.rb, line 1609
def key
  @key
end

The key of the association. This can be any non-void expression.

{ a: b }
  ^

{ foo => bar }
  ^^^

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

value → Node

Source

# File lib/prism/node.rb, line 1623
def value
  @value
end

The value of the association, if present. This can be any non-void expression.

{ foo => bar }
         ^^^

{ x: 1 }
     ^

Locations

Public Instance Methods

operator_loc → Location | nil

Source

# File lib/prism/node.rb, line 1635
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

The Location of the => operator, if present.

{ foo => bar }
