Method Detail

beginFrame

BeginFrameResult beginFrame(Double frameTime,
                            Double deadline,

Parameters:

frameTime - Timestamp of this BeginFrame (milliseconds since epoch). If not set, the current time will be used.

deadline - Deadline of this BeginFrame (milliseconds since epoch). If not set, the deadline will be calculated from the frameTime and interval.

interval - The interval between BeginFrames that is reported to the compositor, in milliseconds. Defaults to a 60 frames/second interval, i.e. about 16.666 milliseconds.

screenshot - If set, a screenshot of the frame will be captured and returned in the response. Otherwise, no screenshot will be captured.

Returns:
