V0.0.3

Release Notes

• allow Out[] params for object methods

• provide returnsSelf annotation to avoid wrapper creation if the returned reference is the same object:

  @CObj
  class Foo {
    @CObj.returnsSelf
    def foo(): Foo = extern
  }
  
  val f1 = new Foo
  val f2 = f1.foo()

  f1.foo() returns f1, not a new Foo, i.e. f1 and f2 are the same object.

• Mutable and updatesSelf annotations allow to update the C reference hold by a wrapper object.
  Useful for data structures, where an update operation possibly returns a new C reference:

  @CObj.Mutable
  class GList(var __ref: CObj.Ref[Byte]) {
    @CObj.updatesThis
    def append(elem: Ptr[Byte]): GList = extern
  }

• add nullable annotation to suppress wrapping if the external function returns null:

  @CObj
  class Foo {
    @CObj.nullable
    def foo(): Foo = extern
  }

  If the external call for Foo.foo() returns null, the result of Foo.foo() is also null,
  instead of new Foo(null).
