# File lib/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
初始化一个新的 ProgramNode
节点。

# File lib/prism/node.rb, line 14931 def self.type :program_node end
返回此节点类型的符号表示形式。请参阅 ‘Node::type`。
公共实例方法
源码
# File lib/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
为节点实现 case-equality。 这实际上是 ==,但不比较位置的值。 仅检查位置是否存在。
