    • putOrAdd

      public int putOrAdd(int key, int putValue, int additionValue)
      Trove-inspired API method. An equivalent of the following code: 
        if (containsKey(key))
  {
      int v = (int) (lget() + additionValue);
      lset(v);
      return v;
  }
  else
  {
     put(key, putValue);
     return putValue;
  }
      Parameters:
      key - The key of the value to adjust.
      putValue - The value to put if key does not exist.
      additionValue - The value to add to the existing value if key exists.
      Returns:
      Returns the current value associated with key (after changes).

      Returns the last value saved in a call to containsKey(int).
      See Also:

    • lset

      public int lset(int value)
      Sets the value corresponding to the key saved in the last call to containsKey(int), if and only if the key exists in the map already.
      Returns:
      Returns the previous value stored under the given key.
      See Also:

    • lslot

      public int lslot()
      Returns:
      Returns the slot of the last key looked up in a call to containsKey(int) if it returned true.
