### Public Class Methods

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

Initialize a new `InstanceVariableAndWriteNode` node.

    # File prism/node.rb, line 9770
    def initialize(source, node_id, location, flags, name, name_loc, operator_loc, value)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @name = name
      @name_loc = name_loc
      @operator_loc = operator_loc
      @value = value
    end

type() click to toggle source

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

    # File prism/node.rb, line 9862
    def self.type
      :instance_variable_and_write_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 9868
    def ===(other)
      other.is_a?(InstanceVariableAndWriteNode) &&
        (name === other.name) &&
        (name_loc.nil? == other.name_loc.nil?) &&
        (operator_loc.nil? == other.operator_loc.nil?) &&
        (value === other.value)
    end

accept(visitor) click to toggle source

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

    # File prism/node.rb, line 9782
    def accept(visitor)
      visitor.visit_instance_variable_and_write_node(self)
    end

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

    # File prism/node.rb, line 9787
    def child_nodes
      [value]
    end

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

    end

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

def copy: (?node_id: Integer, ?location: `Location`, ?flags: Integer, ?name: Symbol, ?name_loc: `Location`, ?operator_loc: `Location`, ?value: Prism::node) -> `InstanceVariableAndWriteNode`

    # File prism/node.rb, line 9802
    def copy(node_id: self.node_id, location: self.location, flags: self.flags, name: self.name, name_loc: self.name_loc, operator_loc: self.operator_loc, value: self.value)
      InstanceVariableAndWriteNode.new(source, node_id, location, flags, name, name_loc, operator_loc, value)
