class Prism::AssocNode
Represents a hash key/value pair.
{ a => b } ^^^^^^
Attributes
The key of the association. This can be any non-void expression.
{ a: b } ^ { foo => bar } ^^^ { def a; end => 1 } ^^^^^^^^^^
The value of the association, if present. This can be any non-void expression.
{ foo => bar } ^^^ { x: 1 } ^
Public Class Methods
Initialize a new AssocNode
node.
# File lib/prism/node.rb, line 1162 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
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 1270 def ===(other) other.is_a?(AssocNode) && (key === other.key) && (value === other.value) && (operator_loc.nil? == other.operator_loc.nil?) end

def operator: () -> String?
# File lib/prism/node.rb, line 1249 def operator operator_loc&.slice end
The location of the =>
operator, if present.
{ foo => bar } ^^
# File lib/prism/node.rb, line 1230 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
Save the operator_loc
location using the given saved source so that it can be retrieved later.
# File lib/prism/node.rb, line 1244 def save_operator_loc(repository) repository.enter(node_id, :operator_loc) unless @operator_loc.nil? end
