public EvaluatePersisterFactory(EvaluateStats stats)

Instantiates a new evaluate persister factory.

Parameters:

stats - the evaluation statistics object

Method Detail

createPersister

public Persister createPersister(ServiceParameters params,
                                 RrdRepository repository)

Description copied from interface: PersisterFactory

Creates a visitor that is used to persist attributes in a CollectionSet.

Specified by:

createPersister in interface PersisterFactory

Parameters:

params - used to determine if individual groups or resources in the collection set should be persisted

repository - used to the RRD persisters to build the appropriate RRD structures

Returns:

a Persister that persists the attributes

createPersister

public Persister createPersister(ServiceParameters params,
                                 RrdRepository repository,
                                 boolean dontPersistCounters,
                                 boolean forceStoreByGroup,
                                 boolean dontReorderAttributes)

Description copied from interface: PersisterFactory

Creates a visitor that is used to persist attributes in a CollectionSet.

Specified by:

createPersister in interface PersisterFactory

Parameters:

params - used to determine if individual groups or resources in the collection set should be persisted

repository - used to the RRD persisters to build the appropriate RRD structures

dontPersistCounters - used to disable persistence for counters in order to try and avoid spikes

forceStoreByGroup - forces the given CollectionSet to be persisted as a group

dontReorderAttributes - store attributes in the order they are visited

Returns:

a Persister that persists the attributes

createGroupPersister

public Persister createGroupPersister(ServiceParameters params,
                                      RrdRepository repository,
                                      boolean dontPersistCounters)

Creates a new EvaluatePersister object when storeByGroup is enabled.

Parameters:

params - the service parameters

repository - the repository
