Field Detail

strategy

protected final InstantiatorStrategy strategy

Strategy used by this Objenesi implementation to create classes

---

cache

protected Map cache

Strategy cache. Key = Class, Value = InstantiatorStrategy

Constructor Detail

ObjenesisBase

public ObjenesisBase(InstantiatorStrategy strategy)

Constructor allowing to pick a strategy and using cache

Parameters:

strategy - Strategy to use

---

ObjenesisBase

public ObjenesisBase(InstantiatorStrategy strategy,
                     boolean useCache)

Flexible constructor allowing to pick the strategy and if caching should be used

Parameters:

strategy - Strategy to use

useCache - If ObjectInstantiators should be cached

Method Detail

toString

public String toString()

Overrides:

toString in class Object

---

newInstance

public Object newInstance(Class clazz)

Will create a new object without any constructor being called

Specified by:

newInstance in interface Objenesis

Parameters:

clazz - Class to instantiate

Returns:

New instance of clazz

---

getInstantiatorOf

public 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).

Specified by:

getInstantiatorOf in interface Objenesis

Parameters:

clazz - Class to instantiate

Returns:

Instantiator dedicated to the class
