Add a service listener. The given listener will have its method called when a service with a type matching that specified by the first parameter is discovered.

Specified by:

addServiceListener in interface IDiscoveryLocator

Parameters:

aType - String type to listen for. Must not be null. Must be formatted according to this specific IDiscoveryContainer

aListener - IServiceListener to be notified. Must not be null .

addServiceTypeListener

public void addServiceTypeListener(IServiceTypeListener aListener)

Parameters:

aListener - the listener to be notified. Must not be null.

clearListeners

protected void clearListeners()

dispose

public void dispose()

Description copied from interface: IContainer

Dispose this IContainer instance. The container instance will be made inactive after the completion of this method and will be unavailable for subsequent usage.

Specified by:

dispose in interface IContainer

Overrides:

dispose in class AbstractContainer

fireServiceDiscovered

protected void fireServiceDiscovered(IServiceEvent aServiceEvent)

Calls IServiceListener.serviceDiscovered(IServiceEvent) for all registered IServiceListener

Parameters:

aServiceEvent - The IServiceEvent to send along the call

fireServiceTypeDiscovered

protected void fireServiceTypeDiscovered(IServiceTypeEvent aServiceTypeEvent)

Calls IServiceTypeListener.serviceTypeDiscovered(IServiceTypeEvent) for all registered IServiceTypeListener

Parameters:

aServiceTypeEvent - The IServiceTypeEvent to send along the call

getConfig

protected DiscoveryContainerConfig getConfig()

Returns:

The DiscoveryContainerConfig of this IDiscoveryContainerAdapter

getConnectNamespace

public Namespace getConnectNamespace()

Description copied from interface: IContainer

Get the Namespace for creating a targetID suitable for use as the first parameter in subsequent calls to IContainer.connect(ID, IConnectContext). If this method returns null, then it means that null is expected as a valid parameter in subsequent calls to IContainer.connect(ID, IConnectContext). If this method returns a non-null Namespace, then the targetID parameter in IContainer.connect(ID, IConnectContext) must be non-null instance created of the returned Namespace.

Specified by:

getConnectNamespace in interface IContainer

Returns:

Namespace the namespace associated with subsequent calls to IContainer.connect(ID, IConnectContext). If null, then the targetID instances passed to IContainer.connect(ID, IConnectContext) may be null. If not null, then targetID instances passed to IContainer.connect(ID, IConnectContext) must be instances of the returned Namespace.

getID

public ID getID()

Description copied from interface: IIdentifiable

Return the ID for this 'identifiable' object. The returned ID should be unique within its namespace. May return null.

Specified by:

getID in interface IIdentifiable

Returns:

All IServiceListeners interested in the given IServiceTypeID

getServicesNamespace

public Namespace getServicesNamespace()

Description copied from interface: IDiscoveryLocator

Get a Namespace for services associated with this discovery container adapter. The given Namespace may be used via IServiceIDFactory to create IServiceIDs rather than simple IDs. For example:

 IServiceID serviceID = ServiceIDFactory.getDefault().createServiceID(container.getServicesNamespace(),
                serviceType, serviceName);
