boolean	find(int key) Finds a key in the map.
int	get(int key) Gets the value for this key.
int	getDefaultValue() Get the default value used to indicate an unused entry
IntIterator	keyIterator() Get an iterator over the integer key values held in the hash map
void	put(int key, int value) Adds a key-value pair to the map.
boolean	remove(int key) Removes a key from the map.
void	setDefaultValue(int defaultValue) Set the value to be returned to indicate an unused entry
int	size() Gets the size of the map.

Method Detail

setDefaultValue

void setDefaultValue(int defaultValue)

Set the value to be returned to indicate an unused entry

Parameters:

defaultValue - the value to be returned by get(int) if no entry exists for the supplied key

getDefaultValue

int getDefaultValue()

Get the default value used to indicate an unused entry

Returns:

the value to be returned by get(int) if no entry exists for the supplied key

clear

void clear()

Clear the map.

find

boolean find(int key)

Finds a key in the map.

Parameters:

key - Key

Returns:

true if the key is mapped

get

int get(int key)

Gets the value for this key.

Parameters:

key - Key

Returns:

the value, or the default value if not found.

size

int size()

Gets the size of the map.

Returns:

the size

remove

boolean remove(int key)

Removes a key from the map.

Parameters:

key - Key to remove

Returns:

true if the value was removed

put

void put(int key,
         int value)

Adds a key-value pair to the map.

Parameters:

key - Key

value - Value

keyIterator

IntIterator keyIterator()

Get an iterator over the integer key values held in the hash map

Returns:

an iterator whose next() call returns the key values (in arbitrary order)
