  • Method Details

    • resetToNull

      void resetToNull()

    • capacity

      int capacity()

    • size

      int size()
      Returns:
      the size of this map

    • isEmpty

      boolean isEmpty()
      Returns:
      true if this map is empty (i.e. size is zero)

    • defaultReturnValue

      long defaultReturnValue()
      Returns:
      the value returned from get(long) when no value is present in the map.

    • put

      long put(long key, long value)
      Add a mapping from key to value. Return the old value of key.
      Parameters:
      key - the key to add
      value - the value to add
      Returns:
      the old value of key (or defaultReturnValue()} if there was no mapping)

    • putIfAbsent

      long putIfAbsent(long key, long value)
      Add a mapping from key to value, if one does not already exist. Return the old value of key (or defaultReturnValue()) if one does not exist.
      Parameters:
      key - the key to add
      value - the value to add
      Returns:
      the old value of key (or defaultReturnValue()} if there was no mapping)

    • get

      long get(long key)
      Gets the value associated with key. Returns defaultReturnValue()} if no mapping exists.
      Parameters:
      key - the key to get
      Returns:
      the value of the key (or defaultReturnValue())

    • remove

      long remove(long key)
      Remove a mapping for a key. Return the removed value of key (or defaultReturnValue()) if one does not exist.
      Parameters:
      key - the key to add
      Returns:
      the removed value of (or defaultReturnValue()} if there was no mapping)

    • clear

      void clear()

    • forEach

      void forEach(it.unimi.dsi.fastutil.longs.LongLongBiConsumer consumer)
