NullHashMapLong()

Method Details

put

public V put(long key,
 V val)

Description copied from class: NonBlockingHashMapLong

Maps the specified key to the specified value in the table. The value cannot be null.

The value can be retrieved by calling NonBlockingHashMapLong.get(long) with a key that is equal to the original key.

Overrides:

put in class NonBlockingHashMapLong<V>

Parameters:

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

val - value to be associated with the specified key

Returns:

the previous value associated with key, or null if there was no mapping for key

putIfAbsent

public V putIfAbsent(long key,
 V val)

Description copied from class: NonBlockingHashMapLong

Atomically, do a NonBlockingHashMapLong.put(long, TypeV) if-and-only-if the key is not mapped. Useful to ensure that only a single mapping for the key exists, even if many threads are trying to create the mapping in parallel.

Overrides:

putIfAbsent in class NonBlockingHashMapLong<V>

Returns:

the previous value associated with the specified key, or null if there was no mapping for the key

get

public V get(Object key)

Description copied from class: NonBlockingHashMapLong

Auto-boxing version of NonBlockingHashMapLong.get(long).

Specified by:

get in interface Map<Long,V>

Overrides:

get in class NonBlockingHashMapLong<V>
