# class Prism::CallAndWriteNode

Represents the use of the ‘&&=` operator on a call.

    foo.bar &&= value
    ^^^^^^^^^^^^^^^^^

### Attributes

read_name[R]

Represents the name of the method being called.

    foo.bar &&= value # read_name `:bar`
        ^^^

receiver[R]

The object that the method is being called on. This can be either ‘nil` or any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

    foo.bar &&= value
    ^^^

value[R]

Represents the value being assigned.

    foo.bar &&= value
                ^^^^^

write_name[R]

Represents the name of the method being written to.

    foo.bar &&= value # write_name `:bar=`
        ^^^

### 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.

    def ===(other)
      other.is_a?(CallAndWriteNode) &&
        (flags === other.flags) &&
        (receiver === other.receiver) &&
        (call_operator_loc.nil? == other.call_operator_loc.nil?) &&
        (message_loc.nil? == other.message_loc.nil?) &&
        (read_name === other.read_name) &&
        (write_name === other.write_name) &&
        (operator_loc.nil? == other.operator_loc.nil?) &&
        (value === other.value)
