def initialize(source, node_id, location, flags, operator_loc, variable)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @operator_loc = operator_loc
  @variable = variable
end

type() 点击以切换源代码

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

===(other) 点击以切换源代码

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

# File prism/node.rb, line 6612
def ===(other)
  other.is_a?(EmbeddedVariableNode) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (variable === other.variable)
end

accept(visitor) 点击以切换源代码

def accept: (Visitor visitor) -> void

# File prism/node.rb, line 6542
def accept(visitor)
  visitor.visit_embedded_variable_node(self)
end

end

copy(node_id: self.node_id, location: self.location, flags: self.flags, operator_loc: self.operator_loc, variable: self.variable) 点击以切换源代码

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?operator_loc: Location, ?variable: InstanceVariableReadNode | ClassVariableReadNode | GlobalVariableReadNode | BackReferenceReadNode | NumberedReferenceReadNode) -> EmbeddedVariableNode

# File prism/node.rb, line 6562
def copy(node_id: self.node_id, location: self.location, flags: self.flags, operator_loc: self.operator_loc, variable: self.variable)
  EmbeddedVariableNode.new(source, node_id, location, flags, operator_loc, variable)
end

deconstruct()

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

别名为: child_nodes
