Method Detail

checkCapacityFactors

protected void checkCapacityFactors(List<Address> members,
                                    Map<Address,Float> capacityFactors)

findWorstPrimaryOwner

protected Address findWorstPrimaryOwner(org.infinispan.distribution.ch.impl.AbstractConsistentHashFactory.Builder builder,
                                        List<Address> nodes)

Returns:

The worst primary owner, or null if the remaining nodes own 0 segments.

findNewPrimaryOwner

protected Address findNewPrimaryOwner(org.infinispan.distribution.ch.impl.AbstractConsistentHashFactory.Builder builder,
                                      Collection<Address> candidates,
                                      Address primaryOwner)

Returns:

The candidate with the worst primary-owned segments/capacity ratio that is also not in the excludes list.
