      • ShortObjectHashtable

        public ShortObjectHashtable()
        Default constructor creates a table with an initial default capacity.

      • ShortObjectHashtable

        public ShortObjectHashtable​(short capacity)
        Constructor creates a table with an initial given capacity. The capacity will be adjusted to the next highest prime in the PRIMES table.
        Parameters:
        capacity - the initial capacity.

      • put

        public void put​(short key,
                java.lang.Object value)
        Adds a key/value pair to the hashtable. If the key is already in the table, the old value is replaced with the new value. If the hashtable is already full, the hashtable will attempt to approximately double in size (it will use a prime number), and all the current entries will be rehashed.
        Parameters:
        key - the key to associated with the given value.
        value - the value to associate with the given key.
        Throws:
        java.lang.ArrayIndexOutOfBoundsException - thrown if the maximum capacity is reached.

      • get

        public java.lang.Object get​(short key)
        Returns the value for the given key.
        Parameters:
        key - the key whose assocated value is to be returned.

      • remove

        public boolean remove​(short key)
        Removes a key from the hashtable
        Parameters:
        key - key to be removed from the hashtable.
        Returns:
        true if key is found and removed, false otherwise.

      • removeAll

        public void removeAll()
        Remove all entries from the hashtable.

      • contains

        public boolean contains​(short key)
        Return true if the given key is in the hashtable.
        Parameters:
        key - the key whose presence in this map is to be tested.

      • size

        public int size()
        Return the number of key/value pairs stored in the hashtable.

      • getKeys

        public short[] getKeys()
        Returns an array containing all the short keys.
