Method Summary

Modifier and Type	Method and Description
static <T> ObjectInstantiator<T>	getInstantiatorOf(Class<T> clazz) Will pick the best instantiator for the provided class.
static <T extends Serializable> ObjectInstantiator<T>	getSerializableObjectInstantiatorOf(Class<T> clazz) Same as getInstantiatorOf(Class) but providing an instantiator emulating ObjectInputStream.readObject behavior.
static <T> T	newInstance(Class<T> clazz) Will create a new object without any constructor being called
static <T extends Serializable> T	newSerializableInstance(Class<T> 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 <T> T newInstance(Class<T> clazz)

Will create a new object without any constructor being called

Type Parameters:

T - Type instantiated

Parameters:

clazz - Class to instantiate

Returns:

New instance of clazz

newSerializableInstance

public static <T extends Serializable> T newSerializableInstance(Class<T> 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)

Type Parameters:

T - Type instantiated

Parameters:

clazz - Class to instantiate

Returns:

New instance of clazz

getInstantiatorOf

public static <T> ObjectInstantiator<T> getInstantiatorOf(Class<T> 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).

Type Parameters:

T - Type to instantiate

Parameters:

clazz - Class to instantiate

Returns:

Instantiator dedicated to the class

getSerializableObjectInstantiatorOf

public static <T extends Serializable> ObjectInstantiator<T> getSerializableObjectInstantiatorOf(Class<T> clazz)

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

Type Parameters:

T - Type to instantiate

Parameters:

clazz - Class to instantiate

Returns:

Instantiator dedicated to the class
