Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Constants

public static final long UNDEFINED_TIME_NANO

Added in API level 21

Undefined time.

Constant Value: -1 (0xffffffffffffffff)

Public Constructors

public FrameStats ()

Added in API level 21

Public Methods

public final long getEndTimeNano ()

Added in API level 21

Gets the end time of the interval for which these statistics apply. The end interval is the time when the last frame was presented.

Returns

The end time in nanoseconds or UNDEFINED_TIME_NANO if there is no frame data.

public final int getFrameCount ()

Added in API level 21

Gets the number of frames for which there is data.

Returns

The number of frames.

public final long getFramePresentedTimeNano (int index)

Added in API level 21

Get the time a frame at a given index was presented.

Parameters

index	The frame index.

Returns

The presented time in nanoseconds or UNDEFINED_TIME_NANO if the frame is not presented yet.

public final long getRefreshPeriodNano ()

Added in API level 21

Gets the refresh period of the display hosting the window(s) for which these statistics apply.

Returns

The refresh period in nanoseconds.

public final long getStartTimeNano ()

Added in API level 21

Gets the start time of the interval for which these statistics apply. The start interval is the time when the first frame was presented.

Returns

The start time in nanoseconds or UNDEFINED_TIME_NANO if there is no frame data.
