Uses of Factory in org.apache.commons.collections4

Methods in org.apache.commons.collections4 that return Factory

Modifier and Type	Method	Description

static <T> Factory<T>	FactoryUtils.exceptionFactory()	Gets a Factory that always throws an exception.
static <T> Factory<T>	FactoryUtils.instantiateFactory(Class<T> classToInstantiate)	Creates a Factory that can create objects of a specific type using a no-args constructor.
static <T> Factory<T>	FactoryUtils.instantiateFactory(Class<T> classToInstantiate, Class<?>[] paramTypes, Object[] args)	Creates a Factory that can create objects of a specific type using the arguments specified to this method.
static <T> Factory<T>	FactoryUtils.nullFactory()	Gets a Factory that will return null each time the factory is used.
static <T> Factory<T>	FactoryUtils.prototypeFactory(T prototype)	Creates a Factory that will return a clone of the same prototype object each time the factory is used.
