getServiceInfo
public IServiceInfo getServiceInfo(IServiceID aServiceId)
Description copied from interface:IDiscoveryLocator
Synchronously retrieve info about the service- Parameters:
aServiceId
- IServiceID of the service to get info about. Must not benull
.- 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- Parameters:
aServiceTypeId
- IServiceTypeID defining the type of service we are interested in getting service info about. Must not benull
- 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 benull
.
-
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 benull
.
-
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. SeeIContainer.getConnectNamespace()
for a explanation of the constraints upon this parameter.connectContext
- any required context to allow this container to authenticate. May benull
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 returnnull
