class Prism::ArrayNode
表示数组字面量。这可以是使用方括号的常规数组,也可以是使用 % 的特殊数组,如 %w 或 %i。
[1, 2, 3] ^^^^^^^^^
属性
表示数组中零个或多个[非空表达式](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression)的列表。
公共类方法
初始化一个新的 ArrayNode
节点。
# File prism/node.rb, line 867 def initialize(source, node_id, location, flags, elements, opening_loc, closing_loc) @source = source @node_id = node_id @location = location @flags = flags @elements = elements @opening_loc = opening_loc @closing_loc = closing_loc end
返回此节点类型的符号表示。请参阅“Node::type”。
# File prism/node.rb, line 987 def self.type :array_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。仅检查位置是否存在。
# File prism/node.rb, line 993 def ===(other) other.is_a?(ArrayNode) && (flags === other.flags) && (elements.length == other.elements.length) && elements.zip(other.elements).all? { |left, right| left === right } && (opening_loc.nil? == other.opening_loc.nil?) && (closing_loc.nil? == other.closing_loc.nil?) end

visitor) -> void

# File prism/node.rb, line 883 def child_nodes [*elements] end
def closing: () -> String?
# File prism/node.rb, line 972 def closing closing_loc&.slice end
表示关闭标记的可选源位置。

# File prism/node.rb, line 948 def closing_loc location = @closing_loc case location when nil nil when Location location else @closing_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF) end end

def inspect -> String
# File prism/node.rb, line 977 def inspect InspectVisitor.compose(self) end
def opening: () -> String?
# File prism/node.rb, line 967 def opening opening_loc&.slice end
表示打开标记的可选源位置。
[1,2,3] # "[" %w[foo bar baz] # "%w[" %I(apple orange banana) # "%I(" foo = 1, 2, 3 # nil
# File prism/node.rb, line 924 def opening_loc location = @opening_loc case location when nil nil when Location location else @opening_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF) end end
使用给定的保存源保存 closing_loc
位置,以便稍后检索。
# File prism/node.rb, line 962 def save_closing_loc(repository) repository.enter(node_id, :closing_loc) unless @closing_loc.nil? end
使用给定的保存源保存 opening_loc
位置,以便稍后检索。
# File prism/node.rb, line 938 def save_opening_loc(repository) repository.enter(node_id, :opening_loc) unless @opening_loc.nil? end
返回此节点类型的符号表示。请参阅“Node#type”。
