class Prism::CallOrWriteNode

Parent:: Prism::Node

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](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=`
    ^^^

=== (other)

Source

# File lib/prism/node.rb, line 3239
def ===(other)
  other.is_a?(CallOrWriteNode) &&
    (flags === other.flags) &&
    (receiver === other.receiver) &&
    (call_operator_loc.nil? == other.call_operator_loc.nil?) &&
    (message_loc.nil? == other.message_loc.nil?) &&

    (write_name === other.write_name) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (value === other.value)
end

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