class Prism::ArrayPatternNode
Represents an array pattern in pattern matching.
foo in 1, 2 ^^^^^^^^^^^ foo in [1, 2] ^^^^^^^^^^^^^ foo in *1 ^^^^^^^^^ foo in Bar[] ^^^^^^^^^^^^ foo in Bar[1, 2, 3] ^^^^^^^^^^^^^^^^^^^
Attributes
attr_reader constant: ConstantReadNode
| ConstantPathNode
| nil
attr_reader posts: Array
attr_reader requireds: Array
attr_reader rest: Prism::node?
Public Class Methods
Initialize a new ArrayPatternNode
node.
# File lib/prism/node.rb, line 1015 def initialize(source, node_id, location, flags, constant, requireds, rest, posts, opening_loc, closing_loc) @source = source @node_id = node_id @location = location @flags = flags @constant = constant @requireds = requireds @rest = rest @posts = posts @opening_loc = opening_loc @closing_loc = closing_loc end
Return a symbol representation of this node type. See Node::type
.

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