Interface MutableDoubleObjectMap<V>

    • Method Detail

      • put

        V put​(double key,
              V 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
        Returns:
        the value previously associated with key if one existed, or null if not
      • putPair

        default V putPair​(DoubleObjectPair<V> keyValuePair)
        This method allows MutableDoubleObjectMap the ability to add an element in the form of DoubleObjectPair<V>.
        Since:
        9.1.0
        See Also:
        put(double, Object)
      • putAll

        void putAll​(DoubleObjectMap<? extends V> 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
        Since:
        5.0.
