> I've just uploaded this release to
> Added the ability to delete the item an Iterator is currently
> indicating (Delete_Item_At (It : Iterator)). Note, this feature
> doesn't yet work for Bags, Maps, Rings or Sets.
> The C++ code offers two variants of accessors such as Queues.Front,
> one of which returns a value while the other returns a
> reference. The second case is now supported by generics such as eg
> The Copy operation of Collections, Queues, Rings and Stacks checks
> for self-assignment before proceeding.
> Synchronized Unbounded Rings now support blocking (balking); eg, an
> attempt to Pop will block until the Ring has something in it to
> pop. For related reasons, the Pop_Value operation is provided.
> AVL Trees had an error (inherited from the C++) which would
> sometimes corrupt the Tree on deletion.
> Containers have new versions of the Visit and Modify generics that
> include a parameter as an argument to Visit and Modify that is
> passed to the Apply routine. Thanks to Steve Doiel.
> Added pragma Elaborate_Body throughout.
> Continued the renaming of Container parameters from Obj to something
> slightly more mnemonic.
> Best wishes for 2000!
