      • addOne

        public boolean addOne​(T value)
        Description copied from interface: IMemory
        Adds one value occurrence to the memory.
        Specified by:
        addOne in interface IMemory<T>
        Returns:
        true if the tuple was not present before in the memory, or (in case of IDeltaBag) is no longer present in the memory
      • addPositive

        public boolean addPositive​(T value,
                                   int count)
        Description copied from interface: IMultiset
        Adds the given number of occurrences to the memory. The count value must be a positive number.
        Specified by:
        addPositive in interface IMultiset<T>
        count - the number of occurrences
        Returns:
        true if the tuple was not present before in the memory
      • addSigned

        public boolean addSigned​(T value,
                                 int count)
        Description copied from interface: IMemory
        Adds the given number of occurrences to the memory. The count value may or may not be negative.

        Precondition if IMultiset: at least the given amount of occurrences exist, if count is negative.

        Precondition if ISetMemory: count is +1 or -1, the latter is only allowed if the set contains the value.

        Specified by:
        addSigned in interface IMemory<T>
        count - the number of occurrences
        Returns:
        true if the tuple was not present before in the memory, or is no longer present in the memory
      • removeOne

        public boolean removeOne​(T value)
        Description copied from interface: IMemory
        Removes one occurrence of the given value from the memory.

        Precondition if IMultiset or ISetMemory: the value must have a positive amount of occurrences in the memory.

        Specified by:
        removeOne in interface IMemory<T>
        Returns:
        true if this was the the last occurrence of the value, or (in case of IDeltaBag) is the first negative occurrence of the value
      • removeOneOrNop

        public boolean removeOneOrNop​(T value)
        Description copied from interface: IMemory
        Removes one occurrence of the given value from the memory, if possible.

        Memory is unchanged and false is returned if IMultiset or ISetMemory and value had no occurrences in the memory

        Specified by:
        removeOneOrNop in interface IMemory<T>
        Returns:
        true if this was the the last occurrence of the value, or (in case of IDeltaBag) is the first negative occurrence of the value
