Method Detail

store

public void store(T object)
           throws StorageException

Specified by:

store in interface Storage<T extends Identifiable,XMLStorageConf>

Throws:

StorageException

retrieve

public <U extends T> U retrieve(Object id,
                                Class<U> clazz)
                         throws StorageException

Description copied from interface: Storage

Retrieves the instance with ID id of type clazz from storage.

Specified by:

retrieve in interface Storage<T extends Identifiable,XMLStorageConf>

Type Parameters:

U - allows enforcing a subtype of the type of the storage via the clazz parameter

Returns:

the retrieved object

Throws:

StorageException - wraps any exception occuring during storage

update

public void update(T object)
            throws StorageException

Specified by:

update in interface Storage<T extends Identifiable,XMLStorageConf>

Throws:

StorageException

delete

public void delete(T object)
            throws StorageException

Specified by:

delete in interface Storage<T extends Identifiable,XMLStorageConf>

Throws:

StorageException

refresh

public void refresh(Object object)
             throws StorageException

Specified by:

refresh in interface Storage<T extends Identifiable,XMLStorageConf>

Throws:

StorageException

start

public void start()
           throws StorageCreationException

Description copied from interface: Storage

Starts referenced resources. Needs to be called after creating an instance of any subclass (except if the subclass especially states that it's not necessary).

Specified by:

start in interface Storage<T extends Identifiable,XMLStorageConf>

Overrides:

start in class AbstractStorage<T extends Identifiable,XMLStorageConf>

Throws:

StorageCreationException - wraps any exception which occurs during the creation of this storage

shutdown

public void shutdown()

Description copied from interface: Storage

Frees eventually aquired resources.

Specified by:

shutdown in interface Storage<T extends Identifiable,XMLStorageConf>

getStorageConf

public XMLStorageConf getStorageConf()

Specified by:

getStorageConf in interface Storage<T extends Identifiable,XMLStorageConf>

registerPostStoreCallback

public void registerPostStoreCallback(T object,
                                      StorageCallback callback)

Description copied from interface: Storage

Registers a callback which is executed right after object is stored with Storage.store(java.lang.Object). Note that entities are supposed to be equals in all persistent entity states transient, attached, detached and removedhttps://vladmihalcea.com/2014/07/30/a-beginners-guide-to-jpahibernate-entity-state-transitions/ and if they're not this method will explicitly has undefined behaviour.

Specified by:

registerPostStoreCallback in interface Storage<T extends Identifiable,XMLStorageConf>

Overrides:

registerPostStoreCallback in class AbstractStorage<T extends Identifiable,XMLStorageConf>

Parameters:

object - the object the callback ought to be registered for

callback - the callback to register

registerPreStoreCallback

public void registerPreStoreCallback(T object,
                                     StorageCallback callback)

Description copied from interface: Storage

Registers a callback which is executed right before object is stored with Storage.store(java.lang.Object). Note that entities are supposed to be equals in all persistent entity states transient, attached, detached and removedhttps://vladmihalcea.com/2014/07/30/a-beginners-guide-to-jpahibernate-entity-state-transitions/ and if they're not this method will explicitly has undefined behaviour.

Specified by:

registerPreStoreCallback in interface Storage<T extends Identifiable,XMLStorageConf>

Overrides:

registerPreStoreCallback in class AbstractStorage<T extends Identifiable,XMLStorageConf>

Parameters:

object - the object the callback ought to be registered for

callback - the callback to register
