Method Detail

addSharedObject

ID addSharedObject(ID sharedObjectID,
                   ISharedObject sharedObject,
                   java.util.Map properties)
                   throws SharedObjectAddException

Add an ISharedObject to this container.

Parameters:

sharedObjectID - the ID of new SharedObject

sharedObject - the ISharedObject instance to add

properties - the Map associated with the added ISharedObject

Returns:

ID the sharedObjectID of the added ISharedObject

Throws:

SharedObjectAddException - if the add cannot be accomplished for any reason

connectSharedObjects

ISharedObjectConnector connectSharedObjects(ID sharedObjectFrom,
                                            ID[] sharedObjectsTo)
                                            throws SharedObjectConnectException

Create an ISharedObjectConnector instance for sending messages from a single ISharedObject to one or more receiver ISharedObjects. All specified ISharedObject instances must be contained by this ISharedObjectContainer.

Parameters:

sharedObjectFrom - the ID of the sender ISharedObject

sharedObjectsTo - the ID[] of the receiver ISharedObjects

Returns:

a valid instance of ISharedObjectConnector. Null if no connector can be made

Throws:

SharedObjectConnectException - thrown if specified sender or receivers do not exist within the context of this container

createSharedObject

ID createSharedObject(SharedObjectDescription sd)
                      throws SharedObjectCreateException

Create a new ISharedObject within this container from the given SharedObjectDescription.

Parameters:

sd - the SharedObjectDescription that describes the SharedObject to be created

Returns:

ID the sharedObjectID of the added ISharedObject

Throws:

SharedObjectCreateException - if the SharedObject cannot be created

disconnectSharedObjects

void disconnectSharedObjects(ISharedObjectConnector connector)
                             throws SharedObjectDisconnectException

Destroy an ISharedObjectConnector instance.

Parameters:

connector - the connector previously created via connectSharedObjects

Throws:

SharedObjectDisconnectException - thrown if specified connector does not exist in the context of this container

getSharedObject

ISharedObject getSharedObject(ID sharedObjectID)

Get the ISharedObject instance corresponding to the given sharedObjectID.

Parameters:

sharedObjectID - of the desired ISharedObject

Returns:

ISharedObject found. Return null if ISharedObject not found.

getSharedObjectConnectors

java.util.List getSharedObjectConnectors(ID sharedObjectFrom)

Get the sharedObjectConnectors associated with the given sharedObjectID

Returns:

List of ISharedObjectConnector instances

getSharedObjectIDs

ID[] getSharedObjectIDs()

Get the array of SharedObject instances currently contained by this ISharedObjectContainer

Returns:

ID[] the IDs of currently contained ISharedObject instances

removeSharedObject

ISharedObject removeSharedObject(ID sharedObjectID)

Remove the given sharedObjectID from this ISharedObjectContainer.

Parameters:

sharedObjectID - the ID of the ISharedObject to remove

Returns:

ISharedObject removed. Returns null if ISharedObject not found

setRemoteAddPolicy

void setRemoteAddPolicy(ISharedObjectPolicy policy)

Set this shared object manager's policy for adding remote shared objects.

Parameters:

policy - the ISharedObjectPolicy instance to use to check the validity of remote requests to add/replicate a shared object into this container
