# NetworkStats

`public final class NetworkStats`
`extends Object` `implements AutoCloseable`

java.lang.Object
↳ | android.app.usage.NetworkStats

Class providing enumeration over buckets of network usage statistics. `NetworkStats` objects are returned as results to various queries in `NetworkStatsManager`.

## Summary

### Nested classes
`class` | `NetworkStats.Bucket` Buckets are the smallest elements of a query result.

### Public methods
`void` | `close()` Closes the enumeration.
`boolean` | `getNextBucket(NetworkStats.Bucket bucketOut)` Fills the recycled bucket with data of the next bin in the enumeration.
`boolean` | `hasNextBucket()` Check if it is possible to ask for a next bucket in the enumeration.

### Protected methods
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
From interface `java.lang.AutoCloseable`
`abstract void` | `close()` Closes this resource, relinquishing any underlying resources.

## Public methods

### close

    public void close ()

Closes the enumeration. Call this method before this object gets out of scope.

### getNextBucket

    public boolean getNextBucket (NetworkStats.Bucket bucketOut)

Fills the recycled bucket with data of the next bin in the enumeration.

Parameters
`bucketOut` | `NetworkStats.Bucket`: Bucket to be filled with data.

Returns
`boolean` | true if successfully filled the bucket, false otherwise.

### hasNextBucket

    public boolean hasNextBucket ()

Check if it is possible to ask for a next bucket in the enumeration.

Returns
`boolean` | true if there is at least one more bucket.

## Protected methods

### finalize

    protected void finalize ()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the `finalize` method to dispose of system resources or to perform other cleanup.

The general contract of `finalize` is that it is invoked if and when the Java™ virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The `finalize` method may take any action, including making this object available again to other threads; the usual purpose of `finalize`, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded.

The `finalize` method of class `Object` performs no special action; it simply returns normally. Subclasses of `Object` may override this definition.

The Java programming language does not guarantee which thread will invoke the `finalize` method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates.

After the `finalize` method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded.

The `finalize` method is never invoked more than once by a Java virtual machine for any given object.

Any exception thrown by the `finalize` method causes the finalization of this object to be halted, but is otherwise ignored.
