Method Summary

static ObjectInstantiator getInstantiatorOf(Class clazz)
          Will pick the best instantiator for the provided class.

static ObjectInstantiator getSerializableObjectInstantiatorOf(Class clazz)
          Same as getInstantiatorOf(Class) but providing an instantiator emulating ObjectInputStream.readObject behavior.

static Object newInstance(Class clazz)
          Will create a new object without any constructor being called

static Serializable newSerializableInstance(Class clazz)
          Will create an object just like it's done by ObjectInputStream.readObject (the default constructor of the first non serializable class will be called)

Method Detail

newInstance

public static final Object newInstance(Class clazz)

Will create a new object without any constructor being called

Parameters:: clazz - Class to instantiate
Returns:: New instance of clazz

newSerializableInstance

public static final Serializable newSerializableInstance(Class clazz)

Will create an object just like it's done by ObjectInputStream.readObject (the default constructor of the first non serializable class will be called)

Parameters:: clazz - Class to instantiate
Returns:: New instance of clazz

getInstantiatorOf

public static final ObjectInstantiator getInstantiatorOf(Class clazz)

Will pick the best instantiator for the provided class. If you need to create a lot of instances from the same class, it is way more efficient to create them from the same ObjectInstantiator than calling newInstance(Class).

Parameters:: clazz - Class to instantiate
Returns:: Instantiator dedicated to the class

getSerializableObjectInstantiatorOf

public static final ObjectInstantiator getSerializableObjectInstantiatorOf(Class clazz)

Same as getInstantiatorOf(Class) but providing an instantiator emulating ObjectInputStream.readObject behavior.

Parameters:: clazz - Class to instantiate
Returns:: Instantiator dedicated to the class
