公共类方法

new(source, node_id, location, flags, locals, statements) 点击切换源代码

初始化一个新的 ProgramNode 节点。

# File prism/node.rb, line 14872
def initialize(source, node_id, location, flags, locals, statements)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @locals = locals
  @statements = statements
end

type() 点击切换源代码

返回此节点类型的符号表示形式。请参阅 ‘Node::type`。

# File prism/node.rb, line 14931
def self.type
  :program_node
end

公共实例方法

===(other) 点击切换源代码

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。

# File prism/node.rb, line 14937
def ===(other)
  other.is_a?(ProgramNode) &&
    (locals.length == other.locals.length) &&
    locals.zip(other.locals).all? { |left, right| left === right } &&
    (statements === other.statements)
end

accept(visitor) 点击切换源代码

def accept: (Visitor visitor) -> void

# File prism/node.rb, line 14882
def accept(visitor)
  visitor.visit_program_node(self)
end

child_nodes() 点击切换源代码

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

# File prism/node.rb, line 14887
def child_nodes
  [statements]
end

也别名为: deconstruct

comment_targets() 点击切换源代码

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

# File prism/node.rb, line 14897
def comment_targets
  [statements] #: Array[Prism::node | Location]
end

compact_child_nodes() 点击切换源代码

def compact_child_nodes: () -> 数组

# File prism/node.rb, line 14892
def compact_child_nodes
  [statements]
end

copy(node_id: self.node_id, location: self.location, flags: self.flags, locals: self.locals, statements: self.statements) 点击切换源代码

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?locals: 数组, ?statements: StatementsNode) -> ProgramNode

# File prism/node.rb, line 14902
def copy(node_id: self.node_id, location: self.location, flags: self.flags, locals: self.locals, statements: self.statements)
  ProgramNode.new(source, node_id, location, flags, locals, statements)
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: (数组 keys) -> { node_id: Integer, location: Location, locals: 数组, statements: StatementsNode }

# File prism/node.rb, line 14910
def deconstruct_keys(keys)
  { node_id: node_id, location: location, locals: locals, statements: statements }
end

inspect() 点击切换源代码

def inspect -> String

# File prism/node.rb, line 14921
def inspect
  InspectVisitor.compose(self)
end

type() 点击切换源代码
