DnsSdDiscoveryContainerAdapter

public DnsSdDiscoveryContainerAdapter(java.lang.String aNamespaceName,
                                      DiscoveryContainerConfig aConfig)
Method Detail

getServiceInfo

public IServiceInfo getServiceInfo(IServiceID aServiceId)
Description copied from interface: IDiscoveryLocator
Synchronously retrieve info about the service

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

getServiceTypes

public IServiceTypeID[] getServiceTypes()
Description copied from interface: IDiscoveryLocator
Synchronously get service info about all known services of given service type

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

getServices

public IServiceInfo[] getServices()
Description copied from interface: IDiscoveryLocator
Synchronously get service info about all known services

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

getServices

public IServiceInfo[] getServices(IServiceTypeID aServiceTypeId)
Description copied from interface: IDiscoveryLocator
Synchronously get service info about all known services of given service type

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

registerService

public void registerService(IServiceInfo serviceInfo)
Description copied from interface: IDiscoveryAdvertiser
Register the given service. This publishes the service defined by the serviceInfo to the underlying publishing mechanism

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

unregisterService

public void unregisterService(IServiceInfo serviceInfo)
Description copied from interface: IDiscoveryAdvertiser
Unregister a previously registered service defined by serviceInfo.

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

connect

public abstract 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.

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.

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.

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