  • Method Details

    • 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, Class<T> clazz)
      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

    • get

      Object get(K key)
      Gets the offset entry for the key
      Parameters:
      key - the key
      Returns:
      the offset value

    • forEach

      void forEach(BiFunction<? super K,? super Object,Boolean> action)
      Performs the given action for each member of the cache
      Parameters:
      action - the action to execute
