public class ReconfigurationEvent
extends AocsEvent

This class encapsulates a reconfiguration event. A reconfiguration event records a reconfiguration inside a reconfiguration manager. This class adds the following attribute to the basic AOCS event class: the indicator of the old reconfiguration, the indicator of the new configuration, the reconfiguration manager that performed the reconfiguration.

Method Detail

initialize

public void initialize(AocsObject creator,
                       short evtType,
                       Reconfigurable reconfigurationManager,
                       short oldConfiguration,
                       short newConfiguration)
Initialize the reconfiguration event.

The creator and evtType parameters are the same as in the initialize method in the super class AocsEvent. The recoveryAction parameter is the recovery action associated to the failure.

AocsEvent.initialize(RtjAocsFramework.BasicObjects.AocsObject, short)

getReconfigurationManager

public Reconfigurable getReconfigurationManager()

getOldConfiguration

public short getOldConfiguration()

getNewConfiguration

public short getNewConfiguration()

resetConfiguration

public void resetConfiguration()
Description copied from interface: Configurable
Clear all configuration information.

Calls to resetConfiguration are propagated to objects that are in a relationship of strong aggregation.

Specified by:
resetConfiguration in interface Configurable
Overrides:
resetConfiguration in class AocsEvent

isConfigured

public boolean isConfigured()
Description copied from interface: Configurable
Return false if some configuration data are missing.

Typically, a false value indicates that a plug-in component is missing or that the object has not been initialized. This is a negative check only: a return value of true cannot guarantee that the object is correctly configured.

Calls to resetConfiguration on an object A are normally not propagated objects of type AocsObject that are contained or otherwise aggregated to A. The rationale for this policy is that all objects of type AocsObject implement interface configurable and therefore their configuration status should be checked externally (probably through the configuration check service of the system manager).

Specified by:
isConfigured in interface Configurable
Overrides:
isConfigured in class AocsEvent

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 AocsEvent

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 AocsEvent
