acquireCandidate

public Map.Entry<TransactionIdentifier,DataTreeCandidateInputOutput.DataTreeCandidateWithVersion> acquireCandidate()
                                                                                                                  throws IOException

The cached candidate needs to be cleared after it is done applying to the DataTree, otherwise it would be keeping deserialized in memory which are not needed anymore leading to wasted memory. This lets the payload know that this was the last time the candidate was needed ant it is safe to be cleared.

Throws:

IOException
