class Prism::ArrayNode

Represents an array literal. This can be a regular array using brackets or a special array using % like %w or %i.

[1, 2, 3]
^^^^^^^^^

Attributes

elements [R]

Represent the list of zero or more [non-void expressions](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression) within the array.

new (source, node_id, location, flags, elements, opening_loc, closing_loc)

Source

# File lib/prism/node.rb, line 861
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

Initialize a new ArrayNode node.

type ()

Source

# File lib/prism/node.rb, line 981
def self.type
  :array_node
end

Return a symbol representation of this node type. See ‘Node::type`.

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 987
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

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.

accept (visitor)

Source

# File lib/prism/node.rb, line 872
def accept(visitor)
  visitor.visit_array_node(self)
end

def accept: (Visitor visitor) -> void

child_nodes ()

# File lib/prism/node.rb, line 877
def child_nodes
  [*elements]
end

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

Also aliased as: deconstruct

closing ()

Source

# File lib/prism/node.rb, line 966

    @closing_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
  end
end

Represents the optional source location for the closing token.
