Class PackageVersion.DefaultPackageVersionComparator

java.lang.Object
  org.rhq.core.domain.content.PackageVersion.DefaultPackageVersionComparator

All Implemented Interfaces:

Serializable, Comparator<PackageVersion>

Enclosing class:

PackageVersion

public static class PackageVersion.DefaultPackageVersionComparator
extends Object
implements Comparator<PackageVersion>, Serializable

This is a default Comparator implementation for package versions. If the package versions being compared both have non-null versions an OSGiVersionComparator is used to compare them. If it fails or if one of the versions is null the package versions are compared by file created date. If the creation date is not specified for one of the package versions, they proclaimed equal.

Note that this comparator is *INCONSISTENT* with equals() and therefore care should be taken when using it with sets and maps (read this documentation).
