Method Detail

connect

public void connect(ID targetID,
                    IConnectContext connectContext)
             throws ContainerConnectException

Description copied from interface: IContainer

Connect to a target remote process or process group. The target identified by the first parameter (targetID) is connected the implementation class. If authentication information is required, the required information is given via via the second parameter (connectContext). Callers note that depending upon the provider implementation this method may block. It is suggested that callers use a separate thread to call this method. This method provides an implementation independent way for container implementations to connect, authenticate, and communicate with a remote service or group of services. Providers are responsible for implementing this operation in a way appropriate to the given remote service (or group) via expected protocol.

Specified by:

connect in interface IContainer

Parameters:

targetID - the ID of the remote server or group to connect to. See IContainer.getConnectNamespace() for a explanation of the constraints upon this parameter.

connectContext - any required context to allow this container to authenticate. May be null if underlying provider does not have any authentication requirements for connection.

Throws:

ContainerConnectException - thrown if communication cannot be established with remote service. Causes can include network connection failure, authentication failure, server error, or if container is already connected.

disconnect

public void disconnect()

Description copied from interface: IContainer

Disconnect. This operation will disconnect the local container instance from any previously joined target or group. Subsequent calls to getConnectedID() will return null.

Specified by:

disconnect in interface IContainer

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

getAdapter

public java.lang.Object getAdapter(java.lang.Class adapter)

Description copied from interface: IContainer

This specialization of IAdaptable.getAdapter() returns additional services supported by this container. A container that supports additional services over and above the methods on IContainer should return them using this method. It is recommended that clients use this method rather than instanceof checks and downcasts to find out about the capabilities of a specific container.

Typically, after obtaining an IContainer, a client would use this method as a means to obtain a more meaningful interface to the container. This interface may or may not extend IContainer. For example, a client could use the following code to obtain an instance of ISharedObjectContainer:

 IContainer newContainer = ContainerFactory.createContainer(type);
 ISharedObjectContainer soContainer = (ISharedObjectContainer) newContainer
                .getAdapter(ISharedObjectContainer.class);
 if (soContainer == null)
        throw new ContainerCreateException(message);
 

Implementations of this method should delegate to IAdapterManager.loadAdapter() if the service cannot be provided directly to ensure extensibility by third-party plug-ins.

Specified by:

getAdapter in interface org.eclipse.core.runtime.IAdaptable

Specified by:

getAdapter in interface IContainer

Parameters:

adapter - the service type to look up

Returns:

the service instance castable to the given class, or null if this container does not support the given service

addServiceListener

public void addServiceListener(IServiceTypeID type,
                               IServiceListener listener)

Specified by:

addServiceListener in interface org.eclipse.ecf.discovery.IDiscoveryLocator

addServiceTypeListener

public void addServiceTypeListener(IServiceTypeListener listener)

Specified by:

getServiceInfo

public IServiceInfo getServiceInfo(IServiceID service)

Specified by:

getServices

public IServiceInfo[] getServices(IServiceTypeID type)

Specified by:

getServicesNamespace

public Namespace getServicesNamespace()

Specified by:

Specified by:

registerService

public void registerService(IServiceInfo serviceInfo)

Specified by:

registerService in interface org.eclipse.ecf.discovery.IDiscoveryAdvertiser

removeServiceListener

public void removeServiceListener(IServiceTypeID type,
                                  IServiceListener listener)

Specified by:

removeServiceListener in interface org.eclipse.ecf.discovery.IDiscoveryLocator

removeServiceTypeListener

public void removeServiceTypeListener(IServiceTypeListener listener)

Specified by:

removeServiceTypeListener in interface org.eclipse.ecf.discovery.IDiscoveryLocator

unregisterService

public void unregisterService(IServiceInfo serviceInfo)

Specified by:

unregisterService in interface org.eclipse.ecf.discovery.IDiscoveryAdvertiser

addListener

public void addListener(IContainerListener listener)

Description copied from interface: IContainer

Add listener to IContainer. The listener's handleEvent method will be synchronously called when container methods are called. Minimally, the events delivered to the listener are as follows

container action	Event
connect start	IContainerConnectingEvent
connect complete	IContainerConnectedEvent
disconnect start	IContainerDisconnectingEvent
disconnect complete	IContainerDisconnectedEvent

Specified by:

addListener in interface IContainer

Parameters:

listener - the IContainerListener to add

getConnectedID

public ID getConnectedID()

Description copied from interface: IContainer

Get the target ID that this container instance has connected to. Returns null if not connected.

Specified by:

getConnectedID in interface IContainer

Returns:

ID of the target we are connected to. Returns null if container not connected.

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:

the ID for this identifiable object. May return null.
