Class SimpleAssignmentStrategy.AnalysisContext.LoadComparator

java.lang.Object
com.tangosol.net.partition.SimpleAssignmentStrategy.AnalysisContext.LoadComparator

All Implemented Interfaces:

java.util.Comparator

Enclosing class:

SimpleAssignmentStrategy.AnalysisContext

public class SimpleAssignmentStrategy.AnalysisContext.LoadComparator

extends java.lang.Object

implements java.util.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.

Field Summary

protected boolean

m_fPrimary Flag for primary or backup load comparison.

Constructor Summary

SimpleAssignmentStrategy.AnalysisContext.LoadComparator(boolean fPrimary)
Construct a LoadComparator.

Method Summary

int	compare(java.lang.Object o1, java.lang.Object o2)
boolean	isPrimary() Return true iff the comparator should use the primary load.
