  • Method Details

    • clone

      public Object clone()
      Disclaimer: If the value type doesn't implement clone(), only the reference is copied. Note: Due to private fields we cannot implement a copy constructor, sorry.
      Overrides:
      clone in class Object
      Parameters:
      source - the primitive hash map to copy

    • containsValue

      public boolean containsValue(int value)

    • containsKey

      public boolean containsKey(long key)

    • get

      public int get(long key)
      Returns the value to which the specified key is mapped, or getKeyNotFoundValue() if this map contains no mapping for the key.

    • put

      public int put(long key, int value)
      Maps the key to the specified value. If a mapping to this key already exists, the previous value will be returned (otherwise getKeyNotFoundValue()).

    • putAll

      public void putAll(LongIntHashMap source)
      Copies all of the mappings from the specified map to this map.

    • remove

      public int remove(long key)
      Removes the key-value mapping from this map. Returns the previously mapped value or getKeyNotFoundValue() if no such mapping exists.

    • size

      public int size()
      Returns the current number of key-value mappings in this map.

    • capacity

      public int capacity()
      Returns the current capacity (buckets) in this map.

    • clear

      public void clear()
      Clears the entire map. The size is 0 after this operation.

    • iterator

      public Iterator<LongIntHashMap.Entry> iterator()
      Returns a new Iterator. Note: this Iterator does not yet support removal of elements.
      Specified by:
      iterator in interface Iterable<LongIntHashMap.Entry>

    • setKeyNotFoundValue

      public int setKeyNotFoundValue(int newKeyNotFoundValue)
      Sets the new key not found value. For primitive types (int, long) the default is -1, for Object types, the default is null.
      Returns:
      the previous key not found value
      See Also:

    • getKeyNotFoundValue

      public int getKeyNotFoundValue()
      Returns the value which is returned if no value has been found for the specified key.

    • toString

      public StringBuilder toString(StringBuilder sb)
      Parameters:
      sb - if null, a new StringBuilder is created
      Returns:
      StringBuilder instance with appended string information of this Entry

    • toString

      public String toString()
      Overrides:
      toString in class Object
