Class FactoryBuilder

java.lang.Object

javax.cache.configuration.FactoryBuilder

public final class FactoryBuilder
extends Object

A convenience class that defines generically typed static methods to aid in the building of Factory instances.

Factory is used by MutableConfiguration to avoid adding non-Serializable instances that would assume usage in the local JVM.

Two styles of builder are available:

• those taking a Class or className. A new instance will be created by the Factory
• those taking a Serializable instance. That instance will be created by the Factory. As the instance is Serializable it no assumption of usage in the local JVM is implied.

Factory instances can also be created in other ways.

Method Detail

factoryOf

public static <T> Factory<T> factoryOf(Class<T> clazz)

Constructs a Factory that will produce factory instances of the specified class.

The specified class must have a no-args constructor.

Type Parameters:

T - the type of the instances produced by the Factory

Parameters:

clazz - the class of instances to be produced by the returned Factory

Returns:

a Factory for the specified clazz

factoryOf

public static <T> Factory<T> factoryOf(String className)

Constructs a Factory that will produce factory instances of the specified class.

The specified class must have a no-args constructor.

Type Parameters:

T - the type of the instances produced by the Factory

Parameters:

className - the class of instances to be produced by the returned Factory

Returns:

a Factory for the specified clazz

factoryOf

public static <T extends Serializable> Factory<T> factoryOf(T instance)

Constructs a Factory that will return the specified factory Serializable instance.

If T is not Serializable use factoryOf(Class) or factoryOf(String).

Type Parameters:

T - the type of the instances returned

Parameters:

instance - the Serializable instance the Factory will return

Returns:

a Factory for the instance
