Interface VersionedPartitions

All Superinterfaces:

Iterable<Long>

All Known Implementing Classes:

DefaultVersionedPartitions

public interface VersionedPartitions
extends Iterable<Long>

VersionedPartitions implementations provide a mapping from partition to version. This data structure is intended to be used to track versions for VersionAwareMapListener allowing those implementations to return the last versions received when needed.

Method Details

getPartitions

VersionedPartitions.Iterator<Integer> getPartitions()

Return the partitions being tracked.

Returns:

the partitions being tracked

getVersion

long getVersion(int iPartition)

Return the version last received for the given partition.

Parameters:

iPartition - the partition in question

Returns:

the version last received for the given partition

iterator

VersionedPartitions.VersionedIterator iterator()

Returns a VersionedPartitions.VersionedIterator that allows retrieval of the next element as a primitive. Additionally the current partition can be returned via VersionedPartitions.Iterator.getPartition().

Specified by:

iterator in interface Iterable<Long>

Returns:

a versioned iterator to return the partition and version
