        This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Map.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).

                                    java.util.function.IntToLongFunction mappingFunction)
        Description copied from interface: Int2LongMap
        If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map.

        Note that contrarily to the default computeIfAbsent(), it is not possible to not add a value for a given key, since the mappingFunction cannot return null. If such a behavior is needed, please use the corresponding nullable version.

        Specified by:
        computeIfAbsent in interface Int2LongMap
        Parameters:
        key - key with which the specified value is to be associated.
        mappingFunction - the function to compute a value.
        Returns:
        the current (existing or computed) value associated with the specified key.
        See Also:
        Map.computeIfAbsent(Object, java.util.function.Function)

                                            java.util.function.IntFunction<? extends java.lang.Long> mappingFunction)
        Description copied from interface: Int2LongMap
        If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map unless it is null.

        Note that this version of computeIfAbsent() should be used only if you plan to return null in the mapping function.

        Specified by:
        computeIfAbsentNullable in interface Int2LongMap
        Parameters:
        key - key with which the specified value is to be associated.
        mappingFunction - the function to compute a value.
        Returns:
        the current (existing or computed) value associated with the specified key, or the default return value if the computed value is null.

      • computeIfAbsentPartial

        public long computeIfAbsentPartial​(int key,
                                           Int2LongFunction mappingFunction)
        Description copied from interface: Int2LongMap
        If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map, unless the key is not present in the given mapping function.

        This version of computeIfAbsent() uses a type-specific version of fastutil's Function. Since Function has a containsKey() method, it is possible to avoid adding a key by having containsKey() return false for that key.

        Specified by:
        computeIfAbsentPartial in interface Int2LongMap
        Parameters:
        key - key with which the specified value is to be associated.
        mappingFunction - the function to compute a value.
        Returns:
        the current (existing or computed) value associated with the specified key.

        Description copied from interface: Int2LongMap
        If the value for the specified key is present, attempts to compute a new mapping given the key and its current mapped value.

        Description copied from interface: Int2LongMap
        Attempts to compute a mapping for the specified key and its current mapped value (or null if there is no current mapping).

        If the function returns null, the mapping is removed (or remains absent if initially absent). If the function itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.

        Description copied from interface: Int2LongMap
        If the specified key is not already associated with a value, associates it with the given value. Otherwise, replaces the associated value with the results of the given remapping function, or removes if the result is null.

        Parameters:
        key - key with which the resulting value is to be associated.
