Specified by:

getUpdateMap in class BaseCollectionStatsStorage

close

public void close()

Description copied from interface: StatsStorage

Close any open resources (files, etc)

isClosed

public boolean isClosed()

Returns:

Whether the StatsStorage implementation has been closed or not

putStaticInfo

public void putStaticInfo(Persistable staticInfo)

Description copied from interface: StatsStorageRouter

Static info: reported once per session, upon initialization

Specified by:

putStaticInfo in interface StatsStorageRouter

Specified by:

putStaticInfo in class BaseCollectionStatsStorage

Parameters:

staticInfo - Static info to store

putUpdate

public void putUpdate(Persistable update)

Description copied from interface: StatsStorageRouter

Updates: stored multiple times per session (periodically, for example)

Specified by:

putUpdate in interface StatsStorageRouter

Specified by:

putUpdate in class BaseCollectionStatsStorage

Parameters:

update - Update info to store

putStorageMetaData

public void putStorageMetaData(StorageMetaData storageMetaData)

Description copied from interface: StatsStorageRouter

Method to store some additional metadata for each session. Idea: record the classes used to serialize and deserialize the static info and updates (as a class name). This is mainly used for debugging and validation.

Specified by:

putStorageMetaData in interface StatsStorageRouter

Specified by:

putStorageMetaData in class BaseCollectionStatsStorage

Parameters:

storageMetaData - Storage metadata to store
