Method Summary

boolean	readRevisionByTime(IDBStoreAccessor dbStoreAccessor, InternalCDORevision revision, long timeStamp, int listChunk) Read a specific past version of a revision.

Method Detail

readRevisionByVersion

boolean readRevisionByVersion(IDBStoreAccessor dbStoreAccessor,
                              InternalCDORevision revision,
                              int version,
                              int listChunk)

Read a specific version of a revision. If this method returns true it is guaranteed that revision.getVersion() == version

Parameters:

dbStoreAccessor - the accessor to use.

revision - the revision object into which the data should be read. The revision has to be have its ID set to the requested object's ID. The version is ignored, as the version parameter is used to determine the version to be read.

version - the version which should be read.

listChunk - the chunk size to read attribute lists.

Returns:

true, if the revision has been found and read correctly. false if the revision could not be found. In this case, the content of revision is undefined.

readRevisionByTime

boolean readRevisionByTime(IDBStoreAccessor dbStoreAccessor,
                           InternalCDORevision revision,
                           long timeStamp,
                           int listChunk)

Read a specific past version of a revision. If this method returns true it is guaranteed that revision.getCreated() <= timeStamp && (getRevised() == 0 || getRevised() >= timeStamp))

Parameters:

dbStoreAccessor - the accessor to use.

revision - the revision object into which the data should be read. The revision has to be have its ID set to the requested object's ID. The version is ignored, as the version parameter is used to determine the version to be read.

timeStamp - the timeStamp which should be used to determine the revision's version.

Returns:

true, if the revision has been found and read correctly. false if the revision could not be found. In this case, the content of revision is undefined.
