  • Field Details

    • emptyRange

      public static final VersionRange emptyRange
      TODO: This should not be OSGi but it has to be that for now since the resolver creates a filter where the min and max are converted into strings. When the filter is evaluated an attempt is made to recreate them as OSGi versions. An empty OSGi Version range.

  • Constructor Details

    • VersionRange

      public VersionRange(Version minVersion, boolean includeMin, Version maxVersion, boolean includeMax)
      Constructs a VersionRange with the specified minVersion and maxVersion.
      Parameters:
      minVersion - the minimum version of the range
      maxVersion - the maximum version of the range

    • VersionRange

      public VersionRange(String versionRange)
      Constructs a VersionRange from the given versionRange String.
      Parameters:
      versionRange - a version range String that specifies a range of versions.

  • Method Details

    • create

      public static VersionRange create(String versionRange)
      Parses a version range from the specified string.

      Note that this method performs a non thread-safe object pooling. Instances are stored in a weak cache, i.e. for multiple calls with the same input it is likely but not guaranteed that the same instance is retrieved. Same holds for concurrent access on this method. Clients must not assume to get the same instance for subsequent calls.

      Parameters:
      versionRange - String representation of the version range. Leading and trailing whitespace will be ignored.
      Returns:
      A VersionRange object representing the version range or null if versionRange is null or an empty string.
      Throws:
      IllegalArgumentException - If versionRange is improperly formatted.
