public class LocalRecoveryActions

extends RecoveryStrategy

This recovery strategy retrieves from the event repository the failure events generated since the last call to doRecovery() and performs the recovery actions associated to each event. Copyright: see the Copyright Notice.

Method Detail

localReset

public void localReset()

setFailureEventRepository

public void setFailureEventRepository(FailureEventRepository r)

This is an initialization method to load the failure event repository and to initialize the internal counter of failure events.

Overrides:

setFailureEventRepository in class RecoveryStrategy

doRecovery

public void doRecovery()

Description copied from class: RecoveryStrategy

Calling this method will cause the recovery strategy to be executed. Conceptually, this should be an abstract method. Its implementation in the base class for all recovery strategies simply performs the forwarding of the doRecovery() call to the next recovery strategy in the chain of linked recovery strategies.

Overrides:

doRecovery in class RecoveryStrategy

reset

public void reset()

Description copied from class: RecoveryStrategy

Set the state of the recovery strategy to 'enabled'.

Specified by:

reset in interface Resettable

Overrides:

reset in class RecoveryStrategy

writeToTelemetry

public void writeToTelemetry(TelemetryStream tmStream)

Description copied from interface: Telemeterable

Direct the object to write its own state to the telemetry stream.

Specified by:

writeToTelemetry in interface Telemeterable

Overrides:

writeToTelemetry in class RecoveryStrategy

getTelemetryImageLength

public int getTelemetryImageLength()

Description copied from interface: Telemeterable

Return the length (in bits) of the telemetry image of the object. This method is useful to verify that the quantity of data generated by a given object is compatible with the capacity of the telemetry channel.

Specified by:

getTelemetryImageLength in interface Telemeterable

Overrides:

getTelemetryImageLength in class RecoveryStrategy
