Method Detail

createWrapper

protected ActionBeanWrapperInterface createWrapper(UidWrapper w,
                                       boolean activate)

toString

public StringBuilder toString(String prefix,
                     StringBuilder sb)

Overrides:

toString in class OSEntryBean

getUid

public Uid getUid(AbstractRecord rec)

return the Uid for given AbstractRecord

Overrides:

getUid in class OSEntryBean

Parameters:

rec - the record whose Uid is required

Returns:

the Uid of the requested record

remove

public String remove()

Remove this AtomicAction from the ObjectStore

Specified by:

remove in interface ActionBeanMBean

Specified by:

remove in interface OSEntryBeanMBean

Overrides:

remove in class OSEntryBean

Returns:

a textual indication of whether the remove operation succeeded

createParticipant

protected LogRecordWrapper createParticipant(AbstractRecord rec,
                                 ParticipantStatus listType)

Extension point for other Bean implementations to provide an implementation bean for its participants. For example @see com.arjuna.ats.internal.jta.tools.osb.mbean.jta.JTAActionBean

Parameters:

rec - the record that should be represented by an MBean

listType - the status of the record

Returns:

the MBean implementation of the participant

createParticipant

protected LogRecordWrapper createParticipant(AbstractRecord rec,
                                 ParticipantStatus listType,
                                 UidWrapper wrapper)

getParticipant

public LogRecordWrapper getParticipant(AbstractRecord rec)

See if there is participant Bean corresponding to the given record

Parameters:

rec - the record for the target participant

Returns:

the bean corresponding to the requested record

register

public void register()

register this bean (and its participants) with the MBeanServer

Overrides:

register in class OSEntryBean

unregister

public void unregister()

unregister this bean (and its participants) with the MBeanServer

Overrides:

unregister in class OSEntryBean

getAgeInSeconds

public long getAgeInSeconds()

Specified by:

getAgeInSeconds in interface ActionBeanMBean

getCreationTime

public String getCreationTime()

Specified by:

getCreationTime in interface ActionBeanMBean

isParticipant

public boolean isParticipant()

Specified by:

isParticipant in interface ActionBeanMBean

setStatus

public boolean setStatus(LogRecordWrapper logrec,
                ParticipantStatus newStatus)

Request a change in status of a participant. For example if a record has a heuristic status then this method could be used to move it back into the prepared state so that the recovery system can replay phase 2 of the commitment protocol

Parameters:

logrec - the record whose status is to be changed

newStatus - the desired status

Returns:

true if the status was changed

getParticipants

public Collection<LogRecordWrapper> getParticipants()

Returns:

the MBeans corresponding to the participants within this action
