JThreads/C++

JThreads/C++ is a Java like threads for C++.

A unique and very useful product, JThreads/C++ is a portable thread abstraction library that mimics the thread classes and primitives found in Java™. Supported on Windows 95, NT and many flavors of Unix, JThreads/C++ simplifies the development of multi-threaded applications by encapsulating all platform-specific function calls inside a well-designed, easy-to-use class library.

How Does It Work?

Java’s support for multi-threaded programming is provided by the following constructs:

The classes java.lang.Thread and java.lang.ThreadGroup
The interface java.lang.Runnable
The synchronized keyword
The methods wait, notify and notifyAll in java.lang.Object

The Java classes java.lang.Thread and java.lang.ThreadGroup are directly translated into the C++ classes JTCThread and JTCThreadGroup. The only difference is that the JThreads/C++ classes have JTC as a prefix instead of the Java package java.lang. The Java interface java.lang.Runnable is implemented as the abstract C++ class JTCRunnable, which contains the pure virtual method run.

Support for the synchronized keyword is slightly more difficult, since it is not possible to add new keywords to C++. JThreads/C++ addresses this issue using two additional classes, JTCMonitor and JTCSynchronized, wich together form the replacement for the synchronized keyword. JTCMonitor also provides the methods wait, notify and notifyAll.
