Constructor Detail

AbstractNakedObjectStore

protected AbstractNakedObjectStore()

Create a new AbstractNakedObjectStore. The CachePolicy is determined by the configuration file. TODO should throw ConfigurationException?

AbstractNakedObjectStore

protected AbstractNakedObjectStore(CachePolicy cache)

Create a new AbstractNakedObjectStore with a specified CachePolicy

Method Detail

getCachedObject

public NakedObject getCachedObject(java.lang.Object oid)

getDebugData

public java.lang.String getDebugData()

Description copied from interface: DebugInfo

Debug details describing the object being investigated

Specified by:

getDebugData in interface DebugInfo

getDebugTitle

public java.lang.String getDebugTitle()

Description copied from interface: DebugInfo

the title for the debug information

Specified by:

getDebugTitle in interface DebugInfo

isLoaded

public boolean isLoaded(java.lang.Object oid)

Description copied from interface: NakedObjectStore

Returns true if the system already holds an object with the specific OID

Specified by:

isLoaded in interface NakedObjectStore

Parameters:

oid -

setLog

public void setLog(Log newLog)

Description copied from interface: NakedObjectStore

Specifies the Log that all future logging calls should be made to.

Specified by:

setLog in interface NakedObjectStore

Parameters:

newLog - org.nakedobjects.utility.Log

setUpdateNotifier

public void setUpdateNotifier(UpdateNotifier notifier)

Specified by:

setUpdateNotifier in interface NakedObjectStore

areObjectsDistributed

public boolean areObjectsDistributed()

Specified by:

areObjectsDistributed in interface NakedObjectStore

areObjectsProxied

public boolean areObjectsProxied()

Specified by:

areObjectsProxied in interface NakedObjectStore

classes

public java.util.Enumeration classes()
                              throws ObjectStoreException

Description copied from interface: NakedObjectStore

Returns a list of all the classes (as NakedClasses) that this object store can handle.

Specified by:

classes in interface NakedObjectStore

Throws:

ObjectStoreException

createInstance

public NakedObject createInstance(NakedClass type)
                           throws ObjectStoreException

Deprecated.

Description copied from interface: NakedObjectStore

Creates an new, persistent, naked object of the specified type - creates a logical instance. This creates a physical instance, makes it persistent, calls the new instance's created method, and ensures the object's initial logical state is stored away.

Specified by:

createInstance in interface NakedObjectStore

Throws:

ObjectStoreException

init

public void init()
          throws ObjectStoreException

Specified by:

init in interface NakedObjectStore

Throws:

ObjectStoreException

loaded

public void loaded(NakedObject object)
            throws ResolveException

Description copied from interface: NakedObjectStore

Called by a client to indicate it has loaded a NakedObject into the system. Should throw ResolveException if the object has already been loaded.

Specified by:

loaded in interface NakedObjectStore

Parameters:

object -

Throws:

ResolveException

persistenceType

public PersistenceType persistenceType()

Specified by:

persistenceType in interface NakedObjectStore

shutdown

public void shutdown()
              throws ObjectStoreException

Specified by:

shutdown in interface NakedObjectStore

Throws:

ObjectStoreException

unloaded

public void unloaded(NakedObject object)

Description copied from interface: NakedObjectStore

Called by a client to indicate it has unloaded a NakedObject from memory. Should throw ResolveException if the object has already been unloaded.

Specified by:

unloaded in interface NakedObjectStore

Parameters:

object -

getLog

                                  NakedObject object)

broadcastObjectUpdate

protected void broadcastObjectUpdate(NakedObject object)

broadcastRemoveUpdate

protected void broadcastRemoveUpdate(NakedCollection collection,
                                     NakedObject object)

log

protected void log()

log
