Method Detail

getPartitionsToFlushOut

int[] getPartitionsToFlushOut(java.util.HashSet<java.lang.Integer> residentPartitions,
                              int minNumNodesToFlushOut)
                              throws LODNetworkException

IDs of the partitions to be flushed out.

Throws:

LODNetworkException
