objenesis-1.2-7.fc16.noarch

Objenesis is a small Java library that serves one purpose: to instantiate a new object of a particular class. Java supports dynamic instantiation of classes using Class.newInstance(); however, this only works if the class has an appropriate constructor. There are many times when a class cannot be instantiated this way, such as when the class contains constructors that require arguments, that have side effects, and/or that throw exceptions. As a result, it is common to see restrictions in libraries stating that classes must require a default constructor. Objenesis aims to overcome these restrictions by bypassing the constructor on object instantiation. Needing to instantiate an object without calling the constructor is a fairly specialized task, however there are certain cases when this is useful: Serialization, Remoting and Persistence - Objects need to be instantiated and restored to a specific state, without invoking code. Proxies, AOP Libraries and Mock Objects - Classes can be subclassed without needing to worry about the super() constructor. * Container Frameworks - Objects can be dynamically instantiated in non-standard ways.
