Interface RmiAgentLoggingService

All Superinterfaces:
java.rmi.Remote, RmiAblePlatformService, RmiAblePlatformServiceEventGenerator
All Known Implementing Classes:
RmiAgentLoggingSystem

public interface RmiAgentLoggingService
extends java.rmi.Remote, RmiAblePlatformService

Defines the behavior of an RMI Agent Logging Service.

The RmiAgentLoggingService interface defines the operations that can be requested of an RMI based Agent Logging Service.

An Agent Logging Service is where agents and other entities of the platform can log AbleAgentSituationReports. These reports can be problems that agents encounter and they want help with. Other agents or users at the console can then view these logs and answer them.

Agents could also log their history to this service. Then users at the console can view the history of an agent.

Method Detail

logAgentSituationReport

public void logAgentSituationReport(AbleAgentSituationReport asr,
                                    AbleSecureKey key)
                             throws java.rmi.RemoteException,
                                    AgentLoggingException
Log an AbleAgentSituationReport to the Logging Service, and notify all interested listeners about this added log.

If secure, the log request will proceed as long as the caller is authenticated.

The logging of duplicate AbleAgentSituationReports will fail.

Parameters:
theAbleAgentSituationReport - The AbleAgentSituationReport that is to be logged.

key - The AbleSecureKey that secures communication.

Throws:
java.rmi.RemoteException - On all remote errors.

AgentLoggingException -

If the AbleAgentSituationReport to be logged is null.

If the caller is not authenticated.

If a duplicate AbleAgentSituationReport is already logged.


updateAgentSituationReport

public void updateAgentSituationReport(AbleAgentSituationReport old,
                                       AbleAgentSituationReport replacement,
                                       AbleSecureKey key)
                                throws java.rmi.RemoteException,
                                       AgentLoggingException
Update an AbleAgentSituationReport in the Logging Service, and notify all interested listeners about this update.

An AbleAgentSituationReport can only be updated if it is in the problem state. History logs may never be changed.

When secure, an AbleAgentSituationReport in the problem state can only be updated by its own VerifiableAgentName.

This method call cannot be delegated. The VerifiableAgentName of the AbleAgentSituationReport that is to be updated must directly make the call.

Parameters:
oldLog - The AbleAgentSituationReport that is to be updated.

updatedLog - The AbleAgentSituationReport that is to replace the old AbleAgentSituationReport.

key - The AbleSecureKey that secures communication.

Throws:
java.rmi.RemoteException - On all remote errors.

AgentLoggingException -

If the updated AbleAgentSituationReport is null.

If the caller is not authenticated.

If the log to be updated does not exist.

If the log being updated to already exists.

If the log we are updating is a history log.

If the caller is not the one who originally logged the log being updated.


removeAgentSituationReports

public void removeAgentSituationReports(java.util.Vector asrsToRemove,
                                        AbleSecureKey key)
                                 throws java.rmi.RemoteException,
                                        AgentLoggingException
Removes AbleAgentSituationReports from the Logging Service, and notify all interested listeners about these removals.

When secure and the AbleAgentSituationReport is verifiable, an AbleAgentSituationReport in the problem state can only be removed by it own VerifiableAgentName, so this method call cannot be delegated in this case.

An AbleAgentSituationReport in the history state can be removed by anyone with equal or greater authority to the VerifiableAgentName of the AbleAgentSituationReport. This call can be delegated in this case.

Parameters:
asrsToRemove - A Vector of all the AbleAgentSituationReports that should be removed.

key - The AbleSecureKey that secures communication.

Throws:
java.rmi.RemoteException - On all remote error.

AgentLoggingException -

If the remove Vector is null.

If an AbleAgentSituationReport that is to be removed does not exist.

If the caller is not authenticated.

If attempting to remove a problem log, and the caller is not the one who originally logged it.

If attempting to remove a history log, and the caller does not have equal to or greater authority as the one who originally logged it.

Return a Vector of all of the AbleAgentSituationReports that match the criteria supplied in the passed in AbleAgentSituationReport.

If fields in the AbleAgentSituationReport are left as null, a match can contain anything in this field. Since timeSent is a primitive type and cannot be set to null, set it to zero to wildcard that field. There is no way to wildcard the search for the state.
