Class ComputeBackupOnFailureRerouteMethod

java.lang.Object
  be.ac.ulg.montefiore.run.totem.domain.model.DomainChangeAdapter
      be.ac.ulg.montefiore.run.totem.domain.model.impl.ComputeBackupOnFailureRerouteMethod

All Implemented Interfaces:

DomainChangeListener, RerouteMethod

public class ComputeBackupOnFailureRerouteMethod
extends DomainChangeAdapter
implements RerouteMethod

Compute another lsp when an lsp has its status changed to DOWN. The parameter remove indicates if the down lsp should be removed or not. If the lsp is removed, the new lsp will have the same id as the deleted one. Otherwise, it will have a new generated id.

Method Detail

start

public void start(java.util.HashMap<java.lang.String,java.lang.String> params)
           throws RerouteMethodInitialisationException

Description copied from interface: RerouteMethod

Starts the reroute method.

Specified by:

start in interface RerouteMethod

Parameters:

params - The parameters to initialise the reroute method. See the specific documentation of each reroute method to have a list of the supported parameters.

Throws:

RerouteMethodInitialisationException - If an error occurs during the initialisation of the controller.

stop

public void stop()

Description copied from interface: RerouteMethod

Stop the reroute method. Should remove listeners.

Specified by:

stop in interface RerouteMethod

setDomain

public void setDomain(Domain domain)

Description copied from interface: RerouteMethod

Specified by:

setDomain in interface RerouteMethod

getStartParameters

public java.util.List<ParameterDescriptor> getStartParameters()

Description copied from interface: RerouteMethod

Returns the optional parameters that can be given when starting the algorithm

Specified by:

getStartParameters in interface RerouteMethod

Returns:
