# class Prism::CallOrWriteNode

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 expressions.

    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=`
        ^^^

    def ===(other)
      other.is_a?(CallOrWriteNode) &&
        (flags === other.flags) &&

        (call_operator_loc.nil? == other.call_operator_loc.nil?) &&

    end

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