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

Public methods

close

Added in API level 23 
 public void close ()

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

getNextBucket

Added in API level 23 
 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. If null, the method does nothing and returning false.
Returns
boolean true if successfully filled the bucket, false otherwise.

hasNextBucket

Added in API level 23 
 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

Added in API level 23 
 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.
