      • computeIfAbsent

        Object computeIfAbsent​(K key,
                       Function<? super K,​? super Object> mapping)
        If the specified key is not present, compute its value from the mapping function (like Java's standard Map one)
        Parameters:
        key - the key to get or associate with the value
        mapping - the mapping function used to compute the value
        Returns:
        the value associated with the key (either the present or the one computed from the mapping function)

      • computeIfPresent

        Object computeIfPresent​(K key,
                        BiFunction<? super K,​? super Object,​? super Object> remapping)
        If the specified key is present, compute a new value from the mapping function (like Java's standard Map one)
        Parameters:
        key - the key to get or associate with the value
        remapping - the remapping function used to compute the new value
        Returns:
        the value associated with the key (either the present or the one computed from the mapping function)

      • contains

        boolean contains​(K key,
                 Object entry)
        Whether the cache contains the key with the given entry value
        Parameters:
        key - the key
        entry - the entry
        Returns:
        true if the key/entry pair is stored in the cache

      • add

        void add​(K key,
         Object offsetValue)
        Adds a value to the cache
        Parameters:
        key - the key to add
        offsetValue - the offset value

      • isFull

        boolean isFull()
        Checks whether the cache is full
        Returns:
        true if full, or false otherwise

      • capacity

        long capacity()
        Gets the cache pool size

      • get

        <T> T get​(K key,

        Gets the offset entry for the key
        Parameters:
        key - the key
        clazz - the class object representing the value to be obtained
        Returns:
        the offset value wrapped in an optional
