WeakCounter

```
public interface WeakCounter
```
A weak consistent counter interface.
This interface represents a weak counter in the way that the write operations does not return a consistent results. In this way, all the writes return a CompletableFuture.
Note: the reset operation is not atomic.

Since:

9.0

- Method Detail
  - getName
```
java.lang.String getName()
```
    Returns:
    
    The counter name.
  - getValue
```
long getValue()
```
    It returns the counter's value.
    This value may be not the mot up-to-data value.
    
    Returns:
    
    The counter's value.
  - increment
```
default java.util.concurrent.CompletableFuture<java.lang.Void> increment()
```
    Increments the counter.
  - decrement
```
default java.util.concurrent.CompletableFuture<java.lang.Void> decrement()
```
    Decrements the counter.
  - add
```
java.util.concurrent.CompletableFuture<java.lang.Void> add(long delta)
```
    Adds the given value to the new value.
    
    Parameters:
    
    delta - the value to add.
  - reset
```
java.util.concurrent.CompletableFuture<java.lang.Void> reset()
```
    Resets the counter to its initial value.
  - addListener
```
<T extends CounterListener> Handle<T> addListener(T listener)
```
    Adds a CounterListener to this counter.
    
    Type Parameters:
    
    T - The type of the listener. It must implement CounterListener.
    
    Parameters:
    
    listener - The listener to add.
    
    Returns:
    
    A Handle that allows to remove the listener via Handle.remove() ()}.
  - getConfiguration
```
CounterConfiguration getConfiguration()
```
    Returns:
    
    the CounterConfiguration used by this counter.
  - remove
```
java.util.concurrent.CompletableFuture<java.lang.Void> remove()
```
    It removes this counter from the cluster.
    Note that it doesn't remove the counter from the CounterManager. If you want to remove the counter from the CounterManager use CounterManager.remove(String).
    
    Returns:
    
    The CompletableFuture that is completed when the counter is removed from the cluster.
  - sync
```
SyncWeakCounter sync()
```
    It returns a synchronous weak counter for this instance.
    
    Returns:
    
    a SyncWeakCounter.
