store

public ConfigurationPersister.PersistenceResource store(org.jboss.dmr.ModelNode model,
                                                        Set<PathAddress> affectedAddresses)

Persist the given configuration model if ConfigurationPersister.isPersisting() would return true, otherwise return a no-op ConfigurationPersister.PersistenceResource.

Parameters:

model - the model to persist

affectedAddresses - the addresses of the resources that were changed

Returns:

callback to use to control whether the stored model should be flushed to permanent storage. Will not be null

hasStored

public boolean hasStored()
