OAObjectCSDelegate

public OAObjectCSDelegate()

Method Detail

isRemoteThread

public static boolean isRemoteThread()

Returns:

true if the current thread is from the OAClient.getMessage().

isServer

public static boolean isServer(OAObject obj)

Used to determine if this JDK is running as an OAServer or OAClient.

Returns:

true if this is not a Client, either the Server or Stand alone

isWorkstation

public static boolean isWorkstation(OAObject obj)

Used to determine if this JDK is running as an OAServer or OAClient.

Returns:

true if this is not a Client, either the Server or Stand alone

initialize

protected static void initialize(OAObject oaObj)

Called by OAObjectDelegate.initialize(). If Object is being created on workstation, then it needs to be flagged that it is only on the client.

isInServerSideCache

public static boolean isInServerSideCache(OAObject oaObj)

objectRemovedFromCache

protected static void objectRemovedFromCache(OAObject obj,
                                             int guid)

called when an object has been removed from a client. Need to remove on server side session called by OAObject.finalize

addToServerSideCache

public static void addToServerSideCache(OAObject oaObj)

If Object is not in a Hub, then it could be gc'd on server, while it still exists on a client(s). To keep the object from gc on server, each OAObjectServer maintains a cache to keep "unattached" objects from being gc'd.

addToServerSideCache

public static void addToServerSideCache(OAObject oaObj,
                                        boolean bSendToServer)

removeFromServerSideCache

public static void removeFromServerSideCache(OAObject oaObj)

If Object is not in a Hub, then it could be gc'd on server, while it still exists on a client(s). To keep the object from gc on server, each OAObjectServer maintains a cache to keep "unattached" objects from being gc'd.

createNewObject

protected static Object createNewObject(Class clazz)

Create a new instance of an object. If OAClient.client exists, this will create the object on the server, where the server datasource can initialize object.

addToNewObjectCache

protected static void addToNewObjectCache(OAObject oaObj)

Objects that are so far only on this computer, and have not been sent to other computers (client or server). This is called during initialization. Once they are serialized (oaobject.writeObject), then it will be removed.

removeFromNewObjectCache

protected static boolean removeFromNewObjectCache(OAObject oaObj)

isInNewObjectCache

public static boolean isInNewObjectCache(OAObject oaObj)

createCopy

protected static OAObject createCopy(OAObject oaObj,
                                     String[] excludeProperties)

Create a new copy of an object. If OAClient.client exists, this will create the object on the server.

getServerGuid

protected static int getServerGuid(OAObject obj)

getServerGuid

protected static int getServerGuid(Class clazz)

save

protected static boolean save(OAObject oaObj,
                              int iCascadeRule)

delete

protected static boolean delete(OAObject obj)

20150815 returns true if this should be deleted on this computer, false if it is done on the server.

getServerObject

protected static OAObject getServerObject(Class clazz,
                                          OAObjectKey key)

getServerReferenceBlob

protected static byte[] getServerReferenceBlob(OAObject oaObj,
                                               String linkPropertyName)

getServerReference

protected static Object getServerReference(OAObject oaObj,
                                           String linkPropertyName)

getServerReferenceHub

public static Hub getServerReferenceHub(OAObject oaObj,
                                        String linkPropertyName)

loadReferenceHubDataOnServer

protected static boolean loadReferenceHubDataOnServer(Hub thisHub,
                                                      OASelect select)

fireBeforePropertyChange

protected static void fireBeforePropertyChange(OAObject obj,
                                               String propertyName,
                                               Object oldValue,
                                               Object newValue)

fireAfterPropertyChange

protected static void fireAfterPropertyChange(OAObject obj,
                                              OAObjectKey origKey,
                                              String propertyName,
                                              Object oldValue,
