公共类方法

new (source, node_id, location, flags, target, operator_loc, value)

源代码

# File lib/prism/node.rb, line 4947
def initialize(source, node_id, location, flags, target, operator_loc, value)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @target = target
  @operator_loc = operator_loc
  @value = value
end

初始化一个新的 ConstantPathAndWriteNode 节点。

type ()

源代码

# File lib/prism/node.rb, line 5025
def self.type
  :constant_path_and_write_node
end

返回此节点类型的符号表示。请参阅 ‘Node::type’。

公共实例方法

=== (other)

源代码

# File lib/prism/node.rb, line 5031
def ===(other)
  other.is_a?(ConstantPathAndWriteNode) &&
    (target === other.target) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (value === other.value)
end

为节点实现 case-equality。这实际上是 ==，但不比较位置的值。位置仅检查是否存在。

accept (visitor)

源代码

# File lib/prism/node.rb, line 4958
def accept(visitor)
  visitor.visit_constant_path_and_write_node(self)
end

def accept: (Visitor visitor) -> void

child_nodes ()

源代码

# File lib/prism/node.rb, line 4963
def child_nodes
  [target, value]
end

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

也别名为：deconstruct

comment_targets ()

源代码

# File lib/prism/node.rb, line 4973
def comment_targets
  [target, operator_loc, value] #: Array[Prism::node | Location]
end

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

compact_child_nodes ()

源代码

# File lib/prism/node.rb, line 4968
def compact_child_nodes
  [target, value]
end

def compact_child_nodes: () -> Array

copy (node_id: self.node_id, location: self.location, flags: self.flags, target: self.target, operator_loc: self.operator_loc, value: self.value)

源代码

# File lib/prism/node.rb, line 4978
def copy(node_id: self.node_id, location: self.location, flags: self.flags, target: self.target, operator_loc: self.operator_loc, value: self.value)
  ConstantPathAndWriteNode.new(source, node_id, location, flags, target, operator_loc, value)
end

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?target: ConstantPathNode, ?operator_loc: Location, ?value: Prism::node) -> ConstantPathAndWriteNode

deconstruct ()

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

别名为：child_nodes

deconstruct_keys (keys)

源代码

# File lib/prism/node.rb, line 4986
def deconstruct_keys(keys)
  { node_id: node_id, location: location, target: target, operator_loc: operator_loc, value: value }
end

def deconstruct_keys: (Array keys) -> { node_id: Integer, location: Location, target: ConstantPathNode, operator_loc: Location, value: Prism::node }

inspect ()

源代码

# File lib/prism/node.rb, line 5015
def inspect
  InspectVisitor.compose(self)
end

def inspect -> String

operator ()

源代码

# File lib/prism/node.rb, line 5010
def operator
  operator_loc.slice
end

def operator: () -> String

operator_loc ()

源代码

# File lib/prism/node.rb, line 4994
def operator_loc
  location = @operator_loc
  return location if location.is_a?(Location)
  @operator_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
end

attr_reader operator_loc: Location

save_operator_loc (repository)

源代码

# File lib/prism/node.rb, line 5002
def save_operator_loc(repository)
  repository.enter(node_id, :operator_loc)
end

使用给定的已保存源保存 operator_loc 位置，以便以后可以检索它。
