attr_reader call: `CallNode`

targets[R]

attr_reader targets: Array

### Public Class Methods

new(source, node_id, location, flags, call, targets) click to toggle source

Initialize a new `MatchWriteNode` node.

    # File prism/node.rb, line 12736
    def initialize(source, node_id, location, flags, call, targets)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @call = call
      @targets = targets
    end

type() click to toggle source

Return a symbol representation of this node type. See ‘Node::type`.

    # File prism/node.rb, line 12795
    def self.type
      :match_write_node
    end

### 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.

    # File prism/node.rb, line 12801
    def ===(other)
      other.is_a?(MatchWriteNode) &&
        (call === other.call) &&
        (targets.length == other.targets.length) &&
        targets.zip(other.targets).all? { |left, right| left === right }
    end

accept(visitor) click to toggle source

def accept: (`Visitor` visitor) -> void

    # File prism/node.rb, line 12746
    def accept(visitor)
      visitor.visit_match_write_node(self)
    end

child_nodes() click to toggle source

def `child_nodes`: () -> Array[nil | Node]

    # File prism/node.rb, line 12751
    def child_nodes
      [call, *targets]
    end

Also aliased as: deconstruct
comment_targets() click to toggle source

def `comment_targets`: () -> Array[Node | Location]

    # File prism/node.rb, line 12761
    def comment_targets
      [call, *targets] #: Array[Prism::node | Location]
    end

compact_child_nodes() click to toggle source

def `compact_child_nodes`: () -> Array

    # File prism/node.rb, line 12756
    def compact_child_nodes
      [call, *targets]
    end

copy(node_id: self.node_id, location: self.location, flags: self.flags, call: self.call, targets: self.targets) click to toggle source

def copy: (?node_id: Integer, ?location: `Location`, ?flags: Integer, ?call: `CallNode`, ?targets: Array) -> `MatchWriteNode`

    # File prism/node.rb, line 12766
    def copy(node_id: self.node_id, location: self.location, flags: self.flags, call: self.call, targets: self.targets)
      MatchWriteNode.new(source, node_id, location, flags, call, targets)
    end

deconstruct()

def deconstruct: () -> Array[nil | Node]

Alias for: child_nodes
deconstruct_keys(keys) click to toggle source

def `deconstruct_keys`: (Array keys) -> { node_id: Integer, location: `Location`, call: `CallNode`, targets: Array }

    # File prism/node.rb, line 12774
    def deconstruct_keys(keys)
      { node_id: node_id, location: location, call: call, targets: targets }
    end

inspect() click to toggle source

def inspect -> String

    # File prism/node.rb, line 12785
    def inspect
      InspectVisitor.compose(self)
    end
