public IdentityIntMap(int initialCapacity,
                      float loadFactor)

Construct a new instance with the given initial capacity and load factor.

Parameters:

initialCapacity - the initial capacity

loadFactor - the load factor

IdentityIntMap

public IdentityIntMap(float loadFactor)

Construct a new instance with the given load factor and an initial capacity of 64.

Parameters:

loadFactor - the load factor

IdentityIntMap

public IdentityIntMap(int initialCapacity)

Construct a new instance with the given initial capacity and a load factor of 0.5.

Parameters:

initialCapacity - the initial capacity

IdentityIntMap

public IdentityIntMap()

Method Detail

clone

public IdentityIntMap<T> clone()

Clone this map.

Overrides:

clone in class Object

Returns:

a cloned map

get

public int get(T key,
               int defVal)

Get a value from the map.

Parameters:

key - the key

defVal - the value to return if the key is not found

Returns:

the map value at the given key, or the value of defVal if it's not found

put

public void put(T key,
                int value)

Put a value into the map. Any previous mapping is discarded silently.

Parameters:

key - the key

value - the value to store

clear

public void clear()

toString

public String toString()

Get a string summary representation of this map.

Overrides:

toString in class Object

Returns:

a string representation
