Tools.h++ helps you master time.
Internationalization support
You can internationalize your software with the convenient and easy-to-use framework of
class
RWLocale , and use class RWTimeZone to manipulate time zones and
daylight-saving time. The entire library is eight-bit clean, so you can use it with any
eight-bit character set. Embedded nulls are fully supported.
●
Endian streams
You can transfer information between operating systems with the efficiency of a binary
stream. The endian streams mechanism, which keeps a record of the operating
environment where information originates, allows the stream to be read on any system
regardless of its native size or byte order.
●
Multithread safe
You can count on multithread safety. When compiled with a multithread option, the
library uses multithread safe system facilities, with enough internal locking to maintain
its internal integrity. See the release notes for your compiler.
●
Persistent store
This new version of Tools.h++ enhances an already powerful and sophisticated store
facility. Isomorphic persistence, which maintains an object's pointer relationships, is now
supported for most Tools.h++ collections, including the template-based collections. You
can also implement isomorphic persistence on your own classes. Objects that inherit from
RWCollectable have polymorphic persistence, which not only maintains
pointer-relationships, but also allows processes to restore objects without knowing their
types.
●
Template based classes
Twenty-eight new or re-engineered class templates based on the Standard C++ Library
container classes. You can use the full interface to these classes if your development
environment supports the Standard C++ Library. If you don't have the Standard C++
Library, Tools.h++ supplies template-based classes with a subset of the same interfaces.
●
Generic collection classes
If your compiler does not yet support templates, Tools.h++ includes a set of
template-like classes that use the C++ preprocessor and , a header file
included with most compilers. The interface to these generic classes is similar to the
template-based classes, so you can make an easy transition.
●
Smalltalk-like collection classes
You get a complete library of collection classes, modeled after the Smalltalk-80
programming environment, including
Set , Bag , Queue , Stack, , OrderedCollection,
