Method Summary

Modifier and Type	Method and Description
boolean	containsKey(int key) Returns true if the map contains the key, otherwise false.
boolean	containsValue(V val) Returns true if the map contains one or more values, otherwise false.
<E extends Throwable> void	forEach(IntMap.EntryConsumer<V,E> act) This method work under a read lock, be careful with long operations inside.
V	get(int key) Returns value associated with the key. if the map doesn't contain the key, returns null.
boolean	isEmpty() Returns true if this map contains no key-value mappings.
V	put(int key, V val) Save the pair into the map.
V	putIfAbsent(int key, V val) Does put into the map if a pair isn't present, otherwise returns stored value.
V	remove(int key)
int	size() Returns count of elements.

Method Detail

containsKey

boolean containsKey(int key)

Returns true if the map contains the key, otherwise false.

Parameters:

key - tests key value.

containsValue

boolean containsValue(V val)

Returns true if the map contains one or more values, otherwise false.

Parameters:

val - value to be associated with the specified key.

get

V get(int key)

Returns value associated with the key. if the map doesn't contain the key, returns null.

Parameters:

key - key with which the specified value is to be associated.

put

V put(int key,
      V val)

Save the pair into the map. If a pair is present, returns old value and store new.

Parameters:

key - key with which the specified value is to be associated.

val - value to be associated with the specified key.

remove

V remove(int key)

Parameters:

key - key with which the specified value is to be associated.

putIfAbsent

V putIfAbsent(int key,
              V val)

Does put into the map if a pair isn't present, otherwise returns stored value.

Parameters:

key - key with which the specified value is to be associated..

val - value to be associated with the specified key..

forEach

<E extends Throwable> void forEach(IntMap.EntryConsumer<V,E> act)
                            throws E extends Throwable

This method work under a read lock, be careful with long operations inside.

Parameters:

act - Action.

Throws:

E extends Throwable

size

int size()

Returns count of elements.

isEmpty

boolean isEmpty()

Returns true if this map contains no key-value mappings.
