updateSeeds

Constructor Details

StreamSeedUpdater

public StreamSeedUpdater(Map<String,Map<Integer,Long>> streamSeedMap)

Construct a new StreamSeedUpdater object an initialize it with the seed map.

Parameters:

streamSeedMap - Map<String, Map<Integer, Long>>; the stored seed maps

Method Details

updateSeed

public void updateSeed(String streamId,
 StreamInterface stream,
 int replicationNumber)

Update one seed for the given streamId and replication number. The method should be fully reproducible, and can be based on the previous seed value of the stream, possibly the String representation, and the replication number.

Specified by:

updateSeed in interface StreamUpdater

Parameters:

streamId - String; the id of the stream to update

stream - StreamInterface; the stream to update for this replication

replicationNumber - int; the replication number for which to set the seed value

getFallbackStreamUpdater

public StreamUpdater getFallbackStreamUpdater()

Return the fallback stream updater in case the stream or the replication is not in the seed map.

Returns:

fallbackStreamUpdater StreamUpdater; the fallback stream updater in case the stream or the replication is not in the seed map.

setFallbackStreamUpdater

public void setFallbackStreamUpdater(StreamUpdater fallbackStreamUpdater)

Set a new fallback stream updater in case the stream or the replication is not in the seed map.

Parameters:

fallbackStreamUpdater - StreamUpdater; the new fallback stream updater in case the stream or the replication is not in the seed map.

Throws:

NullPointerException - when fallbackStreamUpdater is null

getStreamSeedMap

public Map<String,Map<Integer,Long>> getStreamSeedMap()

Return the available seed maps for all stored streams, mapping stream ids to seed maps.

Returns:

Map<String, Map<Integer, Long>>; the stored seed maps
