Class IncreasingStartIntervalSet.StartComparator

java.lang.Object

org.jikesrvm.compilers.opt.regalloc.IncreasingStartIntervalSet.StartComparator

All Implemented Interfaces:

Comparator<BasicInterval>

Enclosing class:

IncreasingStartIntervalSet

private static class IncreasingStartIntervalSet.StartComparator
extends Object
implements Comparator<BasicInterval>

Imposes an ascending ordering based on the start points of basic intervals.

Note that this ordering is inconsistent with equals for objects of type MappedBasicInterval. It would consider two MappedBasicIntervals with different containers the same if begin and end would match.
