Wrap an existing Array
into an ArraySeq
of the proper primitive specialization type without copying.
Wrap an existing Array
into an ArraySeq
of the proper primitive specialization type without copying. Any changes to wrapped array will break the expected immutability.
Note that an array containing boxed primitives can be wrapped in an ArraySeq
without copying. For example, val a: Array[Any] = Array(1)
is an array of Object
at runtime, containing Integer
s. An ArraySeq[Int]
can be obtained with a cast: ArraySeq.unsafeWrapArray(a).asInstanceOf[ArraySeq[Int]]
. The values are still boxed, the resulting instance is an ArraySeq.ofRef. Writing ArraySeq.unsafeWrapArray(a.asInstanceOf[Array[Int]])
does not work, it throws a ClassCastException
at runtime.
