### Public Class Methods

new (source, node_id, location, flags, call, targets)
Source

    # File lib/prism/node.rb, line 13673
    def initialize(source, node_id, location, flags, call, targets)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @call = call
      @targets = targets
    end

Initialize a new `MatchWriteNode` node.

type ()

    # File lib/prism/node.rb, line 13740
    def self.type
      :match_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 13746
    def ===(other)
      other.is_a?(MatchWriteNode) &&
        (call === other.call) &&
        (targets.length == other.targets.length) &&
        targets.zip(other.targets).all? { |left, right| left === right }
    end

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