Constructor Detail

DaemonService

public DaemonService()

Method Detail

start

public void start()

Start the service.

messageReceived

protected void messageReceived(IComponentIdentifier cid,
                               java.lang.String pid)

Called from agent when a handshake message is recieved.

startPlatform

public IFuture<java.lang.Void> startPlatform(StartOptions options)

Start a platform using a configuration. Performs no checking if the new platform runs.

Specified by:

startPlatform in interface IDaemonService

Parameters:

options - The start arguments.

startPlatform

public IFuture<java.lang.Void> startPlatform(StartOptions options,
                                             long wait)

Start a platform using a configuration. Wait for some time to check if the platform doesn't fail. Only detects, if the new platform process exits during that time.

Specified by:

startPlatform in interface IDaemonService

Parameters:

options - The start arguments.

startPlatformAndWait

public IFuture<IComponentIdentifier> startPlatformAndWait(StartOptions options)

Start a platform using a configuration. Wait for successful handshake and return the component identifier of the new platform. Successful handshake means that the init phase of the new platform, including starting of initial components, has completed successfully.

Specified by:

startPlatformAndWait in interface IDaemonService

Parameters:

opt - The start arguments.

adjustOptions

protected IFuture<StartOptions> adjustOptions(StartOptions opt)

Create or adjust options (e.g. fill in classpath) if necessary.

shutdownPlatform

public IFuture<java.lang.Void> shutdownPlatform(IComponentIdentifier cid)

Shutdown a platform.

Specified by:

shutdownPlatform in interface IDaemonService

Parameters:

cid - The platform id.

getPlatforms

public IFuture<java.util.Set<IComponentIdentifier>> getPlatforms()

Get the component identifiers of all (managed) platforms.

Specified by:

getPlatforms in interface IDaemonService

Returns:

Collection of platform ids.

addChangeListener

public IFuture<java.lang.Void> addChangeListener(IRemoteChangeListener<IComponentIdentifier> listener)

Add a change listener.

Specified by:

addChangeListener in interface IDaemonService

Parameters:

listener - The change listener.

removeChangeListener

public IFuture<java.lang.Void> removeChangeListener(IRemoteChangeListener<IComponentIdentifier> listener)
