Class IncreasingEndMappedIntervalSet.EndComparator

java.lang.Object

org.jikesrvm.compilers.opt.regalloc.IncreasingEndMappedIntervalSet.EndComparator

All Implemented Interfaces:

Comparator<BasicInterval>

Enclosing class:

IncreasingEndMappedIntervalSet

private static class IncreasingEndMappedIntervalSet.EndComparator
extends Object
implements Comparator<BasicInterval>

Imposes an ascending ordering based on the end points of basic intervals. For mapped basic intervals, the register numbers are also compared.

Note that this ordering would be inconsistent with equals if both objects of type BasicInterval and MappedBasicInterval were contained in the set. A comparison of a MappedBasicInterval with a BasicInterval may consider both to be the same because their begin and end are the same but the equals methods would not consider the objects as equal.
