VersionedPartitions (Oracle® Coherence Java API Reference)

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.

Nested Class Summary

Nested Classes
Modifier and Type	Interface	Description
`static interface`	`VersionedPartitions.Iterator<T>`	An Iterator for partitions being tracked by a `VersionedPartitions` implementation that allows retrieval of the next partition as a `primitive`.
`static interface`	`VersionedPartitions.VersionedIterator`	An Iterator for partitions being tracked by a `VersionedPartitions` implementation that allows retrieval of partition and version.

- Method Detail
  - 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
