class Prism::RangeNode

表示使用了 ‘..` 或 `…` 操作符。

1..2
^^^^

c if a =~ /left/ ... b =~ /right/
     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

属性

left [R]

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
^^^^^

right [R]

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
    ^^^

如果左右两侧都不存在，这将是一个 MissingNode。

公共类方法

new (source, node_id, location, flags, left, right, operator_loc)

源代码

# File lib/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

初始化一个新的 RangeNode 节点。

type ()

源代码

# File lib/prism/node.rb, line 15053
def self.type
  :range_node
end

返回此节点类型的符号表示。请参见 ‘Node::type`。

公共实例方法

=== (other)

源代码

# File lib/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

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

accept (visitor)

源代码

# File lib/prism/node.rb, line 14965
def accept(visitor)
  visitor.visit_range_node(self)
end

def accept: (Visitor visitor) -> void

child_nodes ()

源代码

# File lib/prism/node.rb, line 14970
def child_nodes
  [left, right]
end

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

也别名为：deconstruct

comment_targets ()

源代码

# File lib/prism/node.rb, line 14983
def comment_targets
  [*left, *right, operator_loc] #: Array[Prism::node | Location]
end

def comment_targets: () -> Array[Node | Location]

compact_child_nodes ()

源代码

# File lib/prism/node.rb, line 14975
def compact_child_nodes
  compact = [] #: Array[Prism::node]
  compact << left if left
  compact << right if right
  compact
end

def compact_child_nodes: () -> Array

copy (node_id: self.node_id, location: self.location, flags: self.flags, left: self.left, right: self.right, operator_loc: self.operator_loc)

源代码

# File lib/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 copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?left: Prism::node?, ?right: Prism::node?, ?operator_loc: Location) -> RangeNode

deconstruct ()

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

别名为：child_nodes

deconstruct_keys (keys)

源代码

# File lib/prism/node.rb, line 14996
def deconstruct_keys(keys)
  { node_id: node_id, location: location, left: left, right: right, operator_loc: operator_loc }
end

def deconstruct_keys: (Array keys) -> { node_id: Integer, location: Location, left: Prism::node?, right: Prism::node?, operator_loc: Location }

exclude_end? ()

源代码

# File lib/prism/node.rb, line 15001
def exclude_end?
  flags.anybits?(RangeFlags::EXCLUDE_END)
end

def exclude_end?: () -> bool

inspect ()

源代码

# File lib/prism/node.rb, line 15043
def inspect
  InspectVisitor.compose(self)
end

def inspect -> String

operator ()

源代码

# File lib/prism/node.rb, line 15038
def operator
  operator_loc.slice
end

def operator: () -> String

operator_loc ()

源代码

# File lib/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

‘..` 或 `…` 操作符的位置。

save_operator_loc (repository)

源代码

# File lib/prism/node.rb, line 15033
def save_operator_loc(repository)
  repository.enter(node_id, :operator_loc)
end

使用给定的已保存的源代码保存 operator_loc 位置，以便稍后检索。

type ()

源代码

# File lib/prism/node.rb, line 15048
def type
  :range_node
end
