源代码
# File lib/prism/node.rb, line 12540 def initialize(source, node_id, location, flags, value, pattern, operator_loc) @source = source @node_id = node_id @location = location @flags = flags @value = value @pattern = pattern @operator_loc = operator_loc end
初始化一个新的 MatchPredicateNode
节点。

# File lib/prism/node.rb, line 12618 def self.type :match_predicate_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
源代码
# File lib/prism/node.rb, line 12624 def ===(other) other.is_a?(MatchPredicateNode) && (value === other.value) && (pattern === other.pattern) && (operator_loc.nil? == other.operator_loc.nil?) 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。
