Examples

Usage

var obj0 = $F(1.0), obj1 = $F(2.0);
var r = $(Ref, obj0);
show(r);
show(deref(r)); /* 1.0 */
ref(r, obj1);
show(deref(r)); /* 2.0 */
assign(r, obj0);
show(deref(r)); /* 1.0 */

Collections

var i0 = new(Int, $I(100));
var i1 = new(Int, $I(200));
var x = new(Array, Ref, i0, i1);

print(deref(get(x, $I(0)))); /* 100 */
del(x); /* Contents of `x` still alive */

Shared Pointer

The Ref type is a basic wrapper around a C pointer. It can be used as a type argument to collections to allow them to store generic types. It may also be useful in various circumstances where another level of indirection or mutability is required.
