internalSwitchSubSystemConfiguration

protected void internalSwitchSubSystemConfiguration(
ISubSystemConfiguration configuration)
Description copied from class: SubSystem
Perform the subsystem specific processing required to complete a subsystem configuration switch for a service subsystem. The subsystem will typically query this configuration for interesting properties or policies. It should also reset any state to a fresh start. This supplied implementation does nothing. Subclasses may override if they implement a service subsystem.

Overrides:
internalSwitchSubSystemConfiguration in class SubSystem
Parameters:
configuration - the configuration this subsystem should use from this point.

canSwitchTo

public boolean canSwitchTo(
ISubSystemConfiguration configuration)
Description copied from class: SubSystem
Determine if a service subsystem is capable of switching to this new configuration. This is usually a test of this configuration's type against the type expected by this subsystem. This supplied implementation returns false. Subclasses should override if they implement a service subsystem.

Specified by:
canSwitchTo in interface ISubSystem
Overrides:
canSwitchTo in class SubSystem
Parameters:
configuration - the configuration to which this subsystem may switch
Returns:
true if this subsystem is capable of switching to this configuration, false otherwise. This implementation returns false.
See Also:
ISubSystem.canSwitchTo(ISubSystemConfiguration)

getServiceType

public 
Class getServiceType()
Description copied from class: SubSystem
Return the service type for this subsystem.

Specified by:
getServiceType in interface ISubSystem
Overrides:
getServiceType in class SubSystem
Returns:
the default implementation returns null. Subclasses that implement service subsystems should return a type as specified in the interface.
See Also:
ISubSystem.getServiceType()

initializeSubSystem

public void initializeSubSystem(
IProgressMonitor monitor)
                         throws 
SystemMessageException
Description copied from class: SubSystem
Initialize this subsystem instance after the corresponding IConnectorService connect method finishes. This method should be overridden if any initialization for the subsystem needs to occur at this time.

The default implementation currently does nothing, but overriding methods should call super before doing any other work.

Specified by:
initializeSubSystem in interface ISubSystem
Overrides:
initializeSubSystem in class RemoteProcessSubSystemImpl
Parameters:
monitor - a progress monitor that can be used to show progress during long-running operation. Cancellation is typically not supported since it might leave the system in an inconsistent state.
Throws:
SystemMessageException - if an error occurs during initialization.

uninitializeSubSystem

public void uninitializeSubSystem(
IProgressMonitor monitor)
Description copied from class: SubSystem
Uninitialize this subsystem just after disconnect. The default implementation currently does nothing. Overriding methods should call super after doing their own work.

Specified by:
uninitializeSubSystem in interface ISubSystem
Overrides:
uninitializeSubSystem in class RemoteProcessSubSystemImpl
Parameters:
monitor - a progress monitor that can be used to show progress during long-running operation. Cancellation is typically not supported since it might leave the system in an inconsistent state.
