Interface CipherVersionFactory<CV extends CipherVersion>

Type Parameters:

CV - The type of the CipherVersion to be created.

All Superinterfaces:

org.refcodes.factory.ContextLookupFactory<CV,String,String>

All Known Implementing Classes:

CipherVersionFactoryImpl

public interface CipherVersionFactory<CV extends CipherVersion>
extends org.refcodes.factory.ContextLookupFactory<CV,String,String>

As requirements might arise to use CipherVersion instances with additional attributes or functionality; the CipherVersionFactory can be replaced with a custom implementation instantiating CipherVersion (sub-)types with the additional required attributes or functionality. Additional attributes might be a validity date useful for housekeeping or management purposes.

In case you provide your custom CipherVersionFactory implementation, make sure the cipher version (sub-)type you return fits with the CipherVersion (sub-)type of your custom CipherVersionGenerator. A good approach is to make your custom CipherVersionGenerator make use your custom CipherVersionFactory.

See the default implementations CipherVersionGeneratorImpl, the AbstractCipherVersionGenerator and the CipherVersionFactoryImpl.

Factory method to be implemented by subclasses. Required to create implementation dependent CipherVersion objects.

Specified by:

createInstance in interface org.refcodes.factory.ContextLookupFactory<CV extends CipherVersion,String,String>

Parameters:

aCipherUid - The UID for the cipher to be stored in the CipherVersion

aCipher - The cipher to be stored in the CipherVersion.

Returns:

The CipherVersion with the cipher UID and the cipher
