Constructor Detail

JMDNSDiscoveryContainer

public JMDNSDiscoveryContainer(java.net.InetAddress addr)
                        throws IDCreateException

Throws:

IDCreateException

Method Detail

getConnectedID

public ID getConnectedID()

IContainer methods

Specified by:

getConnectedID in interface IContainer

Returns:

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

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 AbstractDiscoveryContainerAdapter

connect

public void connect(ID targetID1,
                    IConnectContext joinContext)
             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:

targetID1 - the ID of the remote server or group to connect to. See IContainer.getConnectNamespace() for a explanation of the constraints upon this parameter.

joinContext - 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.

handleRuntimeException

protected void handleRuntimeException(java.lang.Throwable t)

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

getServiceInfo

public IServiceInfo getServiceInfo(IServiceID service)

IDiscoveryContainerAdapter methods

Specified by:

getServiceInfo in interface IDiscoveryContainerAdapter

Parameters:

service - IServiceID of the service to get info about. Must not be null.

Returns:

IServiceInfo the service info retrieved. null if no information retrievable.

getServices

public IServiceInfo[] getServices()

Description copied from interface: IDiscoveryContainerAdapter

Synchronously get service info about all known services

Specified by:

getServices in interface IDiscoveryContainerAdapter

Returns:

IServiceInfo[] the resulting array of service info instances. Will not be null. May be of length 0.

getServices

public IServiceInfo[] getServices(IServiceTypeID type)

Description copied from interface: IDiscoveryContainerAdapter

Synchronously get service info about all known services of given service type

Specified by:

getServices in interface IDiscoveryContainerAdapter

Parameters:

type - IServiceTypeID defining the type of service we are interested in getting service info about. Must not be null

Returns:

IServiceInfo[] the resulting array of service info instances. Will not be null. May be of length 0.

getServiceTypes

public IServiceTypeID[] getServiceTypes()

Description copied from interface: IDiscoveryContainerAdapter

Synchronously get service info about all known services of given service type

Specified by:

getServiceTypes in interface IDiscoveryContainerAdapter

Returns:

IServiceTypeID[] the resulting array of service type IDs. Will not be null. May be of length 0.

registerService

public void registerService(IServiceInfo serviceInfo)
                     throws ECFException

Description copied from interface: IDiscoveryContainerAdapter

Specified by:

registerService in interface IDiscoveryContainerAdapter

Parameters:

serviceInfo - IServiceInfo of the service to be published. Must not be null.

Throws:

ECFException - if service info cannot be registered with this service

Specified by:

unregisterService in interface IDiscoveryContainerAdapter

Parameters:

serviceInfo - IServiceInfo defining the service to unregister. Must not be null.
