Enclosing class:

public class SimpleAssignmentStrategy.AnalysisContext.LoadComparator
extends Object
implements Comparator

LoadComparator is a Comparator that can be used to compare two Member objects based on their partition load (as defined by the LoadCalculator).

A member is ordered "lower" than another member if it has a lower member load (as determined by the LoadCalculator). Members with equivalent loads are ordered equivalently.

Note: This comparator does not define an ordering that is "consistent with equals". If used in a context requiring such a natural ordering, it should be chained with comparator that does provide a natural ordering.
