class Prism::ClassVariableWriteNode
Represents writing to a class variable.
@@foo = 1 ^^^^^^^^^
Attributes
The name of the class variable, which is a ‘@@` followed by an [identifier](github.com/ruby/prism/blob/main/docs/parsing_rules.md#identifiers).
@@abc = 123 # name `@@abc` @@_test = :test # name `@@_test`
The value to write to the class variable. This can be any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).
@@foo = :bar ^^^^ @@_xyz = 123 ^^^
Public Class Methods
Initialize a new ClassVariableWriteNode
node.
# File lib/prism/node.rb, line 3838 def initialize(source, node_id, location, flags, name, name_loc, value, operator_loc) @source = source @node_id = node_id @location = location @flags = flags @name = name @name_loc = name_loc @value = value @operator_loc = operator_loc end
Return a symbol representation of this node type. See ‘Node::type`.
# File lib/prism/node.rb, line 3934 def self.type :class_variable_write_node end
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.
