  • Method Details

    • flattenSortedByKey

      public static final int[] flattenSortedByKey​(com.carrotsearch.hppc.IntIntHashMap map)
      Converts an IntIntHashMap into a flat int [] array. The returned arrays contains [key,value] pairs and is sorted in ascending order by key values.

    • flatten

      public static final int[] flatten​(com.carrotsearch.hppc.IntIntHashMap map)
      Converts an IntIntHashMap into a flat int [] array. Even indexes in the flat array represent keys and the corresponding odd indexes -- values. Note: the order of keys in the flat array is arbitrary.

    • addAllFromFlattened

      public static final com.carrotsearch.hppc.IntIntHashMap addAllFromFlattened​(com.carrotsearch.hppc.IntIntHashMap map, int[] flattened)
      Adds all entries from a flat [] array to the provided map. Even indexes in the flat array represent keys and the corresponding odd indexes -- values.
      Returns:
      the input map for convenience
