class Prism::RangeNode
表示使用 ‘..` 或 `…` 操作符。
1..2 ^^^^ c if a =~ /left/ ... b =~ /right/ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
属性
范围的左侧,如果存在。它可以是 ‘nil` 或任何[非空表达式](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression)。
1... ^ hello...goodbye ^^^^^
范围的右侧,如果存在。它可以是 ‘nil` 或任何[非空表达式](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression)。
..5 ^ 1...foo ^^^
如果既没有左侧也没有右侧,这将是一个 MissingNode
。
公共类方法
初始化一个新的 RangeNode
节点。
# File prism/node.rb, line 14954 def initialize(source, node_id, location, flags, left, right, operator_loc) @source = source @node_id = node_id @location = location @flags = flags @left = left @right = right @operator_loc = operator_loc end
返回此节点类型的符号表示。请参阅 ‘Node::type`。
# File prism/node.rb, line 15053 def self.type :range_node end
公共实例方法
为节点实现 case-equality。这实际上是 ==,但不比较位置的值。仅检查是否存在位置。
# File prism/node.rb, line 15059 def ===(other) other.is_a?(RangeNode) && (flags === other.flags) && (left === other.left) && (right === other.right) && (operator_loc.nil? == other.operator_loc.nil?) end
def accept: (Visitor
visitor) -> void

: () -> Array[nil | Node]

def compact_child_nodes
: () -> Array
# File prism/node.rb, line 14975 def compact_child_nodes compact = [] #: Array[Prism::node] compact << left if left compact << right if right compact end
def copy: (?node_id: Integer, ?location: Location
, ?flags: Integer, ?left: Prism::node?, ?right: Prism::node?, ?operator_loc: Location
) -> RangeNode
# File prism/node.rb, line 14988 def copy(node_id: self.node_id, location: self.location, flags: self.flags, left: self.left, right: self.right, operator_loc: self.operator_loc) RangeNode.new(source, node_id, location, flags, left, right, operator_loc) end
def deconstruct_keys
: (Array keys) -> { node_id: Integer, location: Location
, left: Prism::node?, right: Prism::node?, operator_loc
: Location
}
# File prism/node.rb, line 14996 def deconstruct_keys(keys) { node_id: node_id, location: location, left: left, right: right, operator_loc: operator_loc } end

# File prism/node.rb, line 15043 def inspect InspectVisitor.compose(self) end
def operator: () -> String
# File prism/node.rb, line 15038 def operator operator_loc.slice end
‘..` 或 `…` 操作符的位置。
# File prism/node.rb, line 15025 def operator_loc location = @operator_loc return location if location.is_a?(Location) @operator_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF) end
使用给定的已保存源保存 operator_loc
位置,以便稍后检索。
# File prism/node.rb, line 15033 def save_operator_loc(repository) repository.enter(node_id, :operator_loc) end
返回此节点类型的符号表示。请参阅 ‘Node#type`。
