    • Constructor Detail

      • IntMap

        public IntMap()

      • IntMap

        public IntMap​(int initialCapacity)

      • IntMap

        public IntMap​(int initialCapacity,
              int no_value)

    • Method Detail

      • size

        public int size()
        Returns the number of elements in this map.
        Returns:
        the number of elements in this map.

      • isEmpty

        public boolean isEmpty()
        Returns true if this map contains no elements.
        Returns:
        true if this map contains no elements.

      • put

        public void put​(int key,
                int value)
        Associates the specified value with the specified key in this map. If the map previously contained a mapping for the key, the old value is replaced.
        Parameters:
        key - key with which the specified value is to be associated
        value - value to be associated with the specified key

      • putOrAdjust

        public void putOrAdjust​(int key,
                        int value,
                        int inc)
        Adjusts the specified value associated with the specified key in this map. If the map previously contained a mapping for the key, the old value is adjusted, otherwise, the value is put.
        Parameters:
        key - key with which the specified value is to be associated
        value - value to be associated with the specified key
        inc - increment to add to the value associated with the key

      • get

        public int get​(int key)
        Returns the value to which the specified key is mapped, or -1 if this map contains no mapping for the key.

        More formally, if this map contains a mapping from a key k to a value v such that (key==-1 ? k==-1 : key == k), then this method returns v; otherwise it returns -1. (There can be at most one such mapping.)

        A return value of #FREE necessarily indicate that the map contains no mapping for the key.

        put(int, int)

      • containsKey

        public boolean containsKey​(int key)
        Returns true if this map contains a mapping for the specified key.
        Parameters:
        key - The key whose presence in this map is to be tested
        Returns:
        true if this map contains a mapping for the specified key.

      • clear

        public void clear​(int key)
        Remove the value to which the specified key is mapped.
        Parameters:
        key - key with which the specified value is to be cleared

      • clear

        public void clear()
        Removes all of the mappings from this map. The map will be empty after this call returns.
