        public void ensureCapacity​(int c)
        Ensures, that the list backend can store at least c elements. This method does nothing, if the new capacity is less than the current capacity.
        Parameters:
        c - the new capacity of the list.

      • getAge

        public long getAge​(long key)

      • getNext

        public long getNext​(long key)

      • getPrevious

        public long getPrevious​(long key)
        Returns the entry that is either equal or less than this key.
        Parameters:
        key -
        Returns:

      • containsKey

      • findKeyPosition

        public int findKeyPosition​(long coordinate,
                           boolean greater)
        Tries to locate the key that matches the given key-parameter as closely as possible. If greater is set to true, then - if the coordinate is not contained in the list - the next coordinate is given, else the previous one is returned.
        Parameters:
        coordinate -
        greater -
        Returns:

      • getKeyAt

      • findKey

        public long findKey​(long key,
                    boolean upperBounds)

      • removeAll

        public boolean removeAll​(long age)
        Expects a sorted (ascending) list of cut-entries that should be removed. You will run into troubles if the list is not sorted.
