Method Detail

getServiceInfo

public IServiceInfo getServiceInfo(IServiceID aServiceId)

Description copied from interface: IDiscoveryLocator

Synchronously retrieve info about the service

Specified by:

getServiceInfo in interface IDiscoveryLocator

Overrides:

getServiceInfo in class DnsSdDiscoveryContainerAdapter

Parameters:

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

Returns:

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

getServiceTypes

public IServiceTypeID[] getServiceTypes()

This always returns the service type found for our local domain Use org.eclipse.ecf.provider.dnssrv.DnsSrvDisocoveryLocator.getServices(IServiceTypeID) with a wildcard query instead.

Specified by:

getServiceTypes in interface IDiscoveryLocator

Overrides:

getServiceTypes in class DnsSdDiscoveryContainerAdapter

Returns:

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

IDiscoveryLocator.getServiceTypes()

getServices

public IServiceInfo[] getServices()

Description copied from interface: IDiscoveryLocator

Synchronously get service info about all known services

Specified by:

getServices in interface IDiscoveryLocator

Overrides:

getServices in class DnsSdDiscoveryContainerAdapter

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

Specified by:

getServices in interface IDiscoveryLocator

Overrides:

getServices in class DnsSdDiscoveryContainerAdapter

Parameters:

aServiceTypeId - 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.

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

Specified by:

connect in class DnsSdDiscoveryContainerAdapter

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.

getContainerName

public String getContainerName()

Specified by:

getContainerName in class AbstractDiscoveryContainerAdapter

Returns:

The name of this discovery container
