Method Summary

Methods

Modifier and Type	Method and Description
DataBucket	combineBuckets(DataBucket[] pBuckets) Method to reconstruct a complete DataBucket with the help of party filled buckets plus a revision-delta which determines the necessary steps back.
LogValue	combineBucketsForModification(int pRevisionsToRestore, long pNewBucketKey, DataBucket[] pBuckets, boolean pFullDump) Method to reconstruct a complete DataBucket for reading as well as a DataBucket for serializing with the datas to write already on there.

Method Detail

combineBuckets

DataBucket combineBuckets(DataBucket[] pBuckets)

Method to reconstruct a complete DataBucket with the help of party filled buckets plus a revision-delta which determines the necessary steps back.

Parameters:

pBuckets - the base of the complete DataBucket

Returns:

the complete DataBucket

combineBucketsForModification

LogValue combineBucketsForModification(int pRevisionsToRestore,
                                     long pNewBucketKey,
                                     DataBucket[] pBuckets,
                                     boolean pFullDump)

Method to reconstruct a complete DataBucket for reading as well as a DataBucket for serializing with the datas to write already on there.

Parameters:

pRevisionsToRestore - number of revisions to restore

pNewBucketKey - bucket key of the new bucket

pBuckets - the base of the complete DataBucket

pFullDump - boolean if entire bucket should be written. Must be triggered from extern since it is based on the revisionToRestore-Param

Returns:

a LogValue holding a complete DataBucket for reading a one for writing
