name ist optional Method Detail abortTarget protected synchronized void abortTarget(Transaction ta)(Code) activatedObject protected OzoneCompatible activatedObject() throws Exception(Code) Liefert referenz auf das eigentliche objekt; das objekt wird nachgeladen, wenn es gerade nicht aktiv ist; waehrend einer update-ta wird nur der clone bearbeitet und somit auch nicht nachgeladen allLockers public DxCollection allLockers()(Code) Gibt collection mit entweder dem writeLocker oder allen readLockern, d.h. alle potentiell behindernden transaktionen clusterID protected ClusterID clusterID()(Code) commitTarget protected synchronized void commitTarget(Transaction ta)(Code) createShadow protected synchronized void createShadow() throws Exception(Code) deleteTarget public void deleteTarget()(Code) equals public boolean equals(Object obj)(Code) True, wenn beide auf ein OzoneCompatible mit gleicher ID verweisen. finalizeTarget public void finalizeTarget() throws Exception(Code) id public ObjectID id()(Code) invokeTarget public Object invokeTarget(Env env, String methodName, String sig, Object[] args) throws Exception(Code) isCreated public boolean isCreated()(Code) isDeleted public boolean isDeleted()(Code) loadExternal protected void loadExternal(ObjectInput in) throws IOException, ClassNotFoundException(Code) Aus stream lesen - fuer ClusterSpace. objID ist normalerweise referenz auf objID in object lockLevel public int lockLevel(Transaction ta)(Code) name public String name()(Code) nameTarget public void nameTarget(String _name)(Code) notifyAllTAs public synchronized void notifyAllTAs(Transaction ta)(Code) objectClass protected Class objectClass() throws Exception(Code) ozoneProxy public OzoneProxy ozoneProxy()(Code) permissions public Permissions permissions()(Code) readExternal public synchronized void readExternal(ObjectInput in) throws IOException, ClassNotFoundException(Code) Aus stream lesen - fuer DxDiskHashtable. objID ist normalerweise referenz auf objID in object setClusterID protected void setClusterID(ClusterID _clusterID)(Code) setName public void setName(String _name)(Code) setObject protected OzoneCompatible setObject(OzoneCompatible obj)(Code) Setzen oder loeschen des objektes. commit() ist unteilbar, deshalb kein snchronized. Achtung: object ist evtl. gerade geclustert und muss vorher eingelagert werden; das darf nicht hier gemacht werden, da diese methode auch vom store benutzt wird. setOwner protected void setOwner(User newOwner)(Code) storeExternal protected void storeExternal(ObjectOutput out) throws IOException(Code) In stream schreiben. wird vom ClusterSpace verwendet. target public OzoneCompatible target()(Code) Liefert referenz auf das eigentliche objekt. darf nicht targetShadow beruecksichtigen, da ClusterSPace darauf aufbaut. targetClone public OzoneCompatible targetClone() throws Exception(Code) Build a copy of the encap object. This is based on serialization, so no clone() method must be implemented by OzoneObjects. targetShadow public OzoneCompatible targetShadow()(Code) touch public void touch()(Code) touchCount protected int touchCount()(Code) touchTime protected long touchTime()(Code) touched protected boolean touched()(Code) upgradeLockLevel protected synchronized void upgradeLockLevel(Transaction ta, int lockLevel) throws Exception(Code) writeExternal public void writeExternal(ObjectOutput out) throws IOException(Code) In stream schreiben - fuer DxDiskHashtable Methods inherited from org.ozoneDB.DxLib.DxObject public Object clone()(Code)(Java Doc) public boolean isLess(DxCompatible obj)(Code)(Java Doc) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
