| 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.
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 close ()
Closes the enumeration. Call this method before this object gets out of scope.
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. |
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. |
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 JavaTM 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.
