1. Prism::
  2. ArrayPatternNode

class Prism::ArrayPatternNode

Represents an array pattern in pattern matching.

foo in 1, 2^^^^^^^^^^^foo in [1, 2]^^^^^^^^^^^^^foo in *bar^^^^^^^^^^^foo in Bar[]^^^^^^^^^^^^foo in Bar[1, 2, 3]^^^^^^^^^^^^^^^^^^^

Attributes

constant[R]

Represents the optional constant preceding theArray

foo in Bar[]       ^^^foo in Bar[1, 2, 3]       ^^^foo in Bar::Baz[1, 2, 3]       ^^^^^^^^
posts[R]

Represents the elements after the rest element of the array pattern.

foo in *bar, baz             ^^^
requireds[R]

Represents the required elements of the array pattern.

foo in [1, 2]        ^  ^
rest[R]

Represents the rest element of the array pattern.

foo in *bar       ^^^^

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