DJProf is an experimental Java profiling tool which employs AspectJ to insert the necessary instrumentation for profiling rather than, for example, the Java Machine Profiler Interface (JVMPI). DJProf can be used to profile Java programs without modification (i.e. there is no need to recompile them for profiling) and does not require the user to have any knowledge of AspectJ. The Load-Time Weaving capability of AspectJ is utilised to make this possible. The tool (including its source code) is release under a very straightforward (and unrestrictive) license for the benefit of all.
OVal is a generic validation framework for any kind of Java objects (not only JavaBeans) and allows you:
*
to specify constraints for class fields and method return values
*
to easily validate objects on demand
*
to specify constraints for constructor parameters that are automatically checked when the constructor is called
*
to specify constraints for method parameters that are automatically checked when the method is called
*
to enforce full object validation after an object instance has been created
*
to enforce full object validation before a method of the object is called
*
to enforce full object validation after a method of the object is called
to either let OVal throw constraint violation exceptions during automatic checks or alternatively notify constraint violation listeners.
*
to easily create custom constraints
The short answer is that Qi4j is a framework for domain centric application development, including evolved concepts from AOP, DI and DDD.
Qi4j is an implementation of Composite Oriented Programming, using the standard Java 5 platform, without the use of any pre-processors or new language elements. Everything you know from Java 5 still applies and you can leverage both your experience and toolkits to become more productive with Composite Oriented Programming today.
