Method Detail

connect

public void connect(ID aTargetID,
                    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:

aTargetID - 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

fireServiceDiscovered

public void fireServiceDiscovered(IServiceInfo iinfo)

fireServiceTypeDiscovered

public void fireServiceTypeDiscovered(IServiceTypeID serviceTypeID)

fireServiceUndiscovered

public void fireServiceUndiscovered(IServiceInfo iinfo)

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.

getServiceInfo

public IServiceInfo getServiceInfo(IServiceID service)

Description copied from interface: IDiscoveryLocator

Synchronously retrieve info about the service

Specified by:

getServiceInfo in interface IDiscoveryLocator

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

Specified by:

getServiceTypes in interface IDiscoveryLocator

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

Specified by:

getServices in interface IDiscoveryLocator

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: IDiscoveryLocator

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

Specified by:

getServices in interface IDiscoveryLocator

Returns:

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

registerService

public void registerService(IServiceInfo aServiceInfo)

Description copied from interface: IDiscoveryAdvertiser

Register the given service. This publishes the service defined by the serviceInfo to the underlying publishing mechanism

Specified by:

registerService in interface IDiscoveryAdvertiser

Parameters:

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

unregisterService

public void unregisterService(IServiceInfo aServiceInfo)

Description copied from interface: IDiscoveryAdvertiser

Unregister a previously registered service defined by serviceInfo.

Specified by:

unregisterService in interface IDiscoveryAdvertiser

Parameters:

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

purgeCache

public IServiceInfo[] purgeCache()

Description copied from interface: IDiscoveryLocator

Purges the underlying IServiceInfo cache if available in the current provider

Specified by:

purgeCache in interface IDiscoveryLocator

Overrides:

purgeCache in class AbstractDiscoveryContainerAdapter

Returns:

The previous cache content

See Also:

IDiscoveryLocator.purgeCache()

addServiceListener
