org.pentaho.reporting.libraries.base.boot.PackageSorter

public final class PackageSorter
extends java.lang.Object

Compares two modules for order. A module is considered less than an other module if the module is a required module of the compared module. Modules are considered equal if they have no relation.

When sorting, we match this modules position against all dependent modules until all positions are stable. Circular references are evil and are filtered during the module loading process in the package manager.
