scope - Scope

Method Detail

setPath

public void setPath(String path)

getObjectPath

protected String getObjectPath(String id,
                               String name)

Get object path for given id and name

Overrides:

getObjectPath in class RamPersistence

Parameters:

id - Object ID. The format of the object id is //

name - Object name

Resource path

load

public IPersistable load(String name)

Load a persistent object with the given name. The object must provide either a constructor that takes an input stream as only parameter or an empty constructor so it can be loaded from the persistence store.

Specified by:

load in interface IPersistenceStore

Overrides:

load in class RamPersistence

Parameters:

name - the name of the object to load

Returns:

The loaded object or null if no such object was found

load

public boolean load(IPersistable object)

Load state of an already instantiated persistent object.

Specified by:

load in interface IPersistenceStore

Overrides:

load in class RamPersistence

Parameters:

object - the object to initializ

Returns:

true if the object was initialized, false otherwise

saveObject

protected boolean saveObject(IPersistable object)

Save persistable object

Parameters:

object - Persistable object

Returns:

true on success, false otherwise

save

public boolean save(IPersistable object)

Persist given object.

Specified by:

save in interface IPersistenceStore

Overrides:

save in class RamPersistence

Parameters:

object - Object to store

Returns:

true on success, false otherwise

checkRemoveEmptyDirectories

protected void checkRemoveEmptyDirectories(String base)

Remove empty dirs

Parameters:

base - Base directory

remove

public boolean remove(String name)

Delete the persistent object with the given name.

Specified by:

remove in interface IPersistenceStore

Overrides:

remove in class RamPersistence

Parameters:

name - the name of the object to delete

Returns:

true if object was persisted and thus can be removed, false otherwise

remove

public boolean remove(IPersistable object)

Delete the passed persistent object.

Specified by:

remove in interface IPersistenceStore

Overrides:

remove in class RamPersistence
