  net.sourceforge.domian.repository.AbstractRepository<T>
      net.sourceforge.domian.repository.AbstractDomianCoreRepository<T>
          net.sourceforge.domian.repository.UnsupportedRepository<T>

All Implemented Interfaces:

FakeRepository<T>, Repository<T>

public class UnsupportedRepository<T extends Entity>
extends AbstractDomianCoreRepository<T>
implements FakeRepository<T>

Repository to be used if a Repository implementation is needed, but any usage of it is for some reason unsupported/prohibited.

This repository is also suitable as a dummy object. (A dummy object is a test double. For instance, when a non-null Repository object is necessary in some test method, and that object is never invoked; then a dummy object is appropriate.)

Method Detail

iterateAllEntitiesSpecifiedBy

public <V extends T> java.util.Iterator<V> iterateAllEntitiesSpecifiedBy(Specification<V> specification)

Description copied from interface: Repository

Finds and returns all entities approved by the given specification. An iterator is returned for lazy retrieval of the entities.

Specified by:

iterateAllEntitiesSpecifiedBy in interface Repository<T extends Entity>

Parameters:

specification - the entity specification

Returns:

an iterator with all entities approved by the specification argument

findAllEntitiesSpecifiedBy

public <V extends T> java.util.Collection<V> findAllEntitiesSpecifiedBy(Specification<V> specification)

Description copied from interface: Repository

Finds and returns all entities approved by the given specification.

Specified by:

findAllEntitiesSpecifiedBy in interface Repository<T extends Entity>

Parameters:

specification - the entity specification

Returns:

a collection of all entities approved by the specification argument, or an empty set if no entities are found and approved

put

public <V extends T> void put(V entity)

Description copied from interface: Repository

Puts the given entity into this repository.

Specified by:

put in interface Repository<T extends Entity>

Parameters:

entity - the entity to be stored

update

public <V extends T> void update(V entity)

Description copied from interface: Repository

Updates an entity. When an entity is (re)-retrieved, all state changes will be visible, no matter what kinds of repository implementations being involved. Do notice that for all memory-based repositories (and possibly some delegated ones), entity updates are of course immediately visible.

(Only applicable for persistent repositories doing explicit data writes, like PersistenceDefinition.FILE, and possibly PersistenceDefinition.DELEGATED... For all other persistence definitions, this method is redundant/not applicable. Anyway, by applying this method in a consistent manner, an eventual repository migration will not need any code changes.

Specified by:

update in interface Repository<T extends Entity>

removeAllEntitiesSpecifiedBy

public <V extends T> java.lang.Long removeAllEntitiesSpecifiedBy(Specification<V> specification)

Description copied from interface: Repository

Removes all entities approved by the given specification.

Specified by:

removeAllEntitiesSpecifiedBy in interface Repository<T extends Entity>

Parameters:

specification - the entity specification

Returns:

the number of removed entities

remove

public <V extends T> java.lang.Boolean remove(V entity)

Description copied from interface: Repository

Removes the given entity from this repository.

Specified by:

remove in interface Repository<T extends Entity>

Parameters:

entity - the entity to be removed

Returns:

true if the entity is found and removed, otherwise false
