    • toVersionClause

      public static VersionedClause toVersionClause(org.osgi.resource.Resource resource)
      Create a VersionedClause by applying a version range mask to the resource! Masks are defined by Macro._range(String[]). If the resource should represent a project in the bnd workspace, then instead the VersionClause will refer to it as a snapshot version: e.g. ;version=snapshot

    • getAllResources

      public static Set<org.osgi.resource.Resource> getAllResources(org.osgi.service.repository.Repository repository)
      Return all resources from a repository as returned by the wildcard requirement, see createWildcardRequirement()
      Parameters:
      repository - the repository to use
      Returns:
      a set of resources from the repository.

    • compareTo

      public static int compareTo(org.osgi.resource.Resource a, org.osgi.resource.Resource b)
      Compare two resources. This can be used to act as a comparator. The comparison is first done on name and then version.
      Parameters:
      a - the left resource
      b - the right resource
      Returns:
      0 if equal bame and version, 1 if left has a higher name or same name and higher version, -1 otherwise

    • sortByNameVersion

      public static List<org.osgi.resource.Resource> sortByNameVersion(Collection<org.osgi.resource.Resource> resources)
      Sort the resources by symbolic name and version
      Parameters:
      resources - the set of resources to sort
      Returns:
      a sorted set of resources
