Constructor Detail

### IntHashMap

    public IntHashMap()

  Initializes a map with a capacity of 8 and a load factor of 0,25.

### IntHashMap

    public IntHashMap(int capacity)

  Initializes a map with the given capacity and a load factor of 0,25.

Parameters:
  `capacity` - the initial capacity.

### IntHashMap

    public IntHashMap(int capacity,
                      double factor)

  Constructs a new map with initial capacity, and load factor.

  The capacity is the number of keys that can be mapped without resizing the arrays in which keys and values are stored. For efficiency, only a fraction of the elements in those arrays are used. That fraction is the specified load factor. The initial length of the arrays equals the smallest power of two not less than the ratio capacity/factor. The capacity of the map is increased, as necessary. The maximum number of keys that can be mapped is 2^30.

Parameters:
  `capacity` - the initial capacity.
  `factor` - the load factor.

Method Detail

### clear

    public void clear()

  Clears the map.

### get

    public java.lang.Object get(int key)

  Gets the value for this key.

  Parameters:
    `key` - Key
  Returns:
    the value, null if not found.

### size

    public int size()

  Gets the size of the map.

  Returns:
    the size (the number of entries in the map)

### remove

    public boolean remove(int key)

  Removes a key from the map.

  Parameters:
    `key` - Key to remove
  Returns:
    true if the value was removed

### put

    public void put(int key,
                    java.lang.Object value)

  Adds a key-value pair to the map.

  Parameters:
    `key` - Key
    `value` - Value

### keyIterator

    public IntIterator keyIterator()

  Get an iterator over the keys

### valueIterator

    public java.util.Iterator valueIterator()

  Get an iterator over the values

### copy

    public IntHashMap copy()

  Create a copy of the IntHashMap

### display

    public void display()

  Diagnostic display of contents
