|---|---|
long |
addAndGet(K key,
long delta)
Adds delta to the value currently associated with key, and returns the new value.
|
void |
clear()
Clears all entries from the map.
|
long |
decrementAndGet(K key)
Decrements by one the value currently associated with key, and returns the new value.
|
long |
get(K key)
Returns the value associated with key, or zero if there is no value associated with key.
|
long |
getAndAdd(K key,
long delta)
Adds delta to the value currently associated with key, and returns the old value.
|
long |
getAndDecrement(K key)
Decrements by one the value currently associated with key, and returns the old value.
|
long |
getAndIncrement(K key)
Increments by one the value currently associated with key, and returns the old value.
|
long |
incrementAndGet(K key)
Increments by one the value currently associated with key, and returns the new value.
|
boolean |
isEmpty()
If the map is empty, returns true, otherwise false.
|
default DistributedPrimitive.Type |
primitiveType()
Returns the type of primitive.
|
long |
put(K key,
long newValue)
Associates ewValue with key in this map, and returns the value previously
associated with key, or zero if there was no such value.
|
long |
putIfAbsent(K key,
long newValue)
If key is not already associated with a value or if key is associated with
zero, associate it with newValue.
|
long |
remove(K key)
Removes and returns the value associated with key.
|
boolean |
remove(K key,
long value)
If (key, value) is currently in the map, this method removes it and returns
true; otherwise, this method returns false.
|
boolean |
replace(K key,
long expectedOldValue,
long newValue)
If (key, expectedOldValue) is currently in the map, this method replaces
expectedOldValue with newValue and returns true; otherwise, this method return false.
|
int |
size()
Returns the number of entries in the map.
