Class BasicFactory

java.lang.Object

com.scriptbasic.factories.BasicFactory

All Implemented Interfaces:

Factory

public class BasicFactory
extends Object
implements Factory

Implementing the interface Factory this class instantiates the objects using the JDK standard ServiceLoader. A single factory instance will maintain a single instance of each class and subsequent call on the same factory object to the method get(Class) will return the same class instance for the same interface.

The implementation also checks that the argument passed to the method is an interface and not a class.

Method Detail

get

public <T extends FactoryManaged> T get(Class<T> interfAce)

Get an instance of the interface. Calling the method multiple times with the same argument should return the same instance on the same factory. Implementation are encouraged to check that the parameter argument is an interface and not an ordinary class. The implementation checks that the argument is an interface and throws IllegalArgumentException if the argument is a class.

Specified by:

get in interface Factory

Parameters:

interfAce - the interface. It is an error to pass a class that is not an interface. In that case the implementation may throw BasicInterpreterInternalError.

Returns:

the instance implementing the interface.

clean

public void clean()

Description copied from interface: Factory

Clean the factory. Remove all references to the objects that were created by the factory.

When the factory creates thread singletons (thread local instances) then this is important to call this method to release the objects before the thread finishes.
