type ()
Source

    # File lib/prism/node.rb, line 9974
    def self.type
      :instance_variable_operator_write_node
    end

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

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 9980
    def ===(other)
      other.is_a?(InstanceVariableOperatorWriteNode) &&
        (name === other.name) &&
        (name_loc.nil? == other.name_loc.nil?) &&
        (binary_operator_loc.nil? == other.binary_operator_loc.nil?) &&
        (value === other.value) &&
        (binary_operator === other.binary_operator)
    end

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.

Source

    # File lib/prism/node.rb, line 9896
    def accept(visitor)
      visitor.visit_instance_variable_operator_write_node(self)
    end
