  • Method Details

    • put

      void put​(long key, double value)
      Associates a value with the specified key. If a value is already associated with the key in this map, it will be replaced with value.
      Parameters:
      key - the key
      value - the value to associate with value

    • putPair

      default void putPair​(LongDoublePair keyValuePair)
      This method allows MutableLongDoubleMap the ability to add an element in the form of LongDoublePair.
      Since:
      9.1.0
      See Also:
      put(long, double)

    • putAll

      void putAll​(LongDoubleMap map)
      Puts all of the key/value mappings from the specified map into this map. If this map already has a value associated with one of the keys in the map, it will be replaced with the value in map.
      Parameters:
      map - the map to copy into this map

    • updateValues

      void updateValues​(LongDoubleToDoubleFunction function)
      Updates the values in-place.

    • updateValue

      double updateValue​(long key, double initialValueIfAbsent, DoubleToDoubleFunction function)
      Updates or sets the value associated with the key by applying the function to the existing value, if one exists, or to the specified initial value if one does not.
      Parameters:
      key - the key
      initialValueIfAbsent - the initial value to supply to the function if no mapping exists for the key
      function - the function that returns the updated value based on the current value or the initial value, if no value exists
      Returns:
      the new value associated with the key, either as a result of applying function to the value already associated with the key or as a result of applying it to initialValueIfAbsent and associating the result with key
