      public static FsIndexCollection createFsIndexCollection(String... descriptorNames)
      Creates a FsIndexCollection from descriptor names.
      Parameters:
      descriptorNames - The fully qualified, Java-style, dotted descriptor names.

      A FsIndexCollection that includes the indexes from all of the specified files.

    • createFsIndexCollection

      public static FsIndexCollection createFsIndexCollection() throws ResourceInitializationException
      Creates a FsIndexCollection from all index descriptions that can be found via the pattern specified in the system property org.apache.uima.fit.fsindex.import_pattern or via the META-INF/org.apache.uima.fit/fsindexes.txt files in the classpath.
      Returns:
      the auto-scanned indexes.

      ResourceInitializationException - if the index collection could not be assembled

    • scanIndexDescriptors

      public static String[] scanIndexDescriptors() throws ResourceInitializationException
      Get all currently accessible index descriptor locations. A scan is actually only performed on the first call and the locations are cached. To force a re-scan use forceIndexDescriptorsScan().
      Returns:
      an array of locations.
      Throws:
      ResourceInitializationException - if the locations could not be resolved.

    • forceIndexDescriptorsScan

      public static void forceIndexDescriptorsScan()
      Force rescan of index descriptors. The next call to scanIndexDescriptors() will rescan all auto-import locations.
