Examples of org.objenesis.strategy.StdInstantiatorStrategy

org.objenesis.strategy.StdInstantiatorStrategy
Guess the best instantiator for a given class. The instantiator will instantiate the class without calling any constructor. Currently, the selection doesn't depend on the class. It relies on the
- JVM version
- JVM vendor
- JVM vendor version
However, instantiators are stateful and so dedicated to their class. @author Henri Tremblay @see ObjectInstantiator
