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

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。位置仅检查是否存在。

# File 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

accept(visitor) 点击切换源代码

def accept: (Visitor visitor) -> void

# File prism/node.rb, line 12551
def accept(visitor)
  visitor.visit_match_predicate_node(self)
end

child_nodes() 点击切换源代码

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

# File prism/node.rb, line 12556
def child_nodes
  [value, pattern]
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 12566
def comment_targets
  [value, pattern, 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 12561
def compact_child_nodes
  [value, pattern]
end

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

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?value: Prism::node, ?pattern: Prism::node, ?operator_loc: Location) -> MatchPredicateNode

# File prism/node.rb, line 12571
def copy(node_id: self.node_id, location: self.location, flags: self.flags, value: self.value, pattern: self.pattern, operator_loc: self.operator_loc)
  MatchPredicateNode.new(source, node_id, location, flags, value, pattern, 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, value: Prism::node, pattern: Prism::node, operator_loc: Location }

# File prism/node.rb, line 12579
def deconstruct_keys(keys)
  { node_id: node_id, location: location, value: value, pattern: pattern, operator_loc: operator_loc }
end

inspect() 点击切换源代码

def inspect -> String

def operator_loc
  location = @operator_loc
  return location if location.is_a?(Location)
