### Public Instance Methods

name → Symbol
Source

    # File lib/prism/node.rb, line 5513
    def name
      @name
    end

Represents the name of the method being called.

receiver → Node
Source

    # File lib/prism/node.rb, line 5475
    def receiver
      @receiver
    end

    # File lib/prism/node.rb, line 5454
    def attribute_write?
      flags.anybits?(CallNodeFlags::ATTRIBUTE_WRITE)
    end

a call that is an attribute write, so the value being written should be returned

ignore_visibility? ()
Source

    # File lib/prism/node.rb, line 5462
    def ignore_visibility?
      flags.anybits?(CallNodeFlags::IGNORE_VISIBILITY)
    end

a call that ignores method visibility

variable_call? ()
Source

    # File lib/prism/node.rb, line 5446
    def variable_call?
      flags.anybits?(CallNodeFlags::VARIABLE_CALL)
    end

a call that could have been a local variable

## Locations

### Public Instance Methods

call_operator_loc → Location
Source

    # File lib/prism/node.rb, line 5489
    def call_operator_loc
      location = @call_operator_loc
      return location if location.is_a?(Location)
      @call_operator_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
    end

Represents the `Location` of the call operator.

    foo.bar = 1
       ^

message_loc → Location
Source

    # File lib/prism/node.rb, line 5527
    def message_loc
      location = @message_loc
      return location if location.is_a?(Location)
      @message_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
    end

Represents the `Location` of the message.

    foo.bar = 1
        ^^^
