公共类方法

new(source, node_id, location, flags, left, right, operator_loc) 点击切换源代码

初始化一个新的 AndNode 节点。

# File prism/node.rb, line 651
def initialize(source, node_id, location, flags, left, right, operator_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @left = left
  @right = right
  @operator_loc = operator_loc
end

type() 点击切换源代码

返回此节点类型的符号表示。请参阅“Node::type”。

# File prism/node.rb, line 744
def self.type

end

公共实例方法

===(other) 点击切换源代码

实现节点的 case-equality。这实际上是 ==，但不比较位置的值。仅检查位置是否存在。

# File prism/node.rb, line 750
def ===(other)
  other.is_a?(AndNode) &&
    (left === other.left) &&
    (right === other.right) &&
    (operator_loc.nil? == other.operator_loc.nil?)
end

accept(visitor) 点击切换源代码

def accept: (Visitor visitor) -> void

# File prism/node.rb, line 662
def accept(visitor)
  visitor.visit_and_node(self)
end

child_nodes() 点击切换源代码

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

# File prism/node.rb, line 667
def child_nodes
  [left, right]
end

comment_targets() 点击切换源代码

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

# File prism/node.rb, line 677
def comment_targets
  [left, right, operator_loc] #: Array[Prism::node | Location]
end

compact_child_nodes() 点击切换源代码

def compact_child_nodes: () -> Array

# File prism/node.rb, line 672
def compact_child_nodes
  [left, right]
end

copy(node_id: self.node_id, location: self.location, flags: self.flags, left: self.left, right: self.right, operator_loc: self.operator_loc) 点击切换源代码

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?left: Prism::node, ?right: Prism::node, ?operator_loc: Location) -> AndNode

# File prism/node.rb, line 682
def copy(node_id: self.node_id, location: self.location, flags: self.flags, left: self.left, right: self.right, operator_loc: self.operator_loc)
  AndNode.new(source, node_id, location, flags, left, right, operator_loc)
end

deconstruct()

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

别名为：child_nodes

deconstruct_keys(keys) 点击切换源代码

def deconstruct_keys: (Array keys) -> { node_id: Integer, location: Location, left: Prism::node, right: Prism::node, operator_loc: Location }

# File prism/node.rb, line 690

  { node_id: node_id, location: location, left: left, right: right, operator_loc: operator_loc }
end

     ^^^

# File prism/node.rb, line 716
def operator_loc
  location = @operator_loc
  return location if location.is_a?(Location)
  @operator_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
end

save_operator_loc(repository) 点击切换源代码

使用给定的已保存源保存operator_loc位置，以便稍后检索。

# File prism/node.rb, line 724
def save_operator_loc(repository)
  repository.enter(node_id, :operator_loc)
end
