公共类方法

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

源代码

# File lib/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

初始化一个新的 MatchWriteNode 节点。

type ()

源代码

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

返回此节点类型的符号表示。请参见 ‘Node::type`。

公共实例方法

=== (other)

源代码

# File lib/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

实现节点的 case-equality（大小写相等性）。这实际上是 ==，但不比较 location 的值。location 仅检查是否存在。

accept (visitor)

源代码

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

def accept: (Visitor visitor) -> void

child_nodes ()

源代码

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

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

也别名为： deconstruct

comment_targets ()

源代码

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

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

compact_child_nodes ()

源代码

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

def compact_child_nodes: () -> Array

copy (node_id: self.node_id, location: self.location, flags: self.flags, call: self.call, targets: self.targets)

源代码

# File lib/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

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

deconstruct ()

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

别名为：child_nodes

deconstruct_keys (keys)

源代码

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

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

inspect ()

源代码

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

def inspect -> String

type ()

源代码

# File lib/prism/node.rb, line 12790
def type
  :match_write_node
end
