Method Detail

recordEvent

public static void recordEvent(int eventId,
                               int... values)

Records a MicroVG event. The given event identifier must be valid for this logger (i.e. between DRAW_PATH_COLOR and DRAW_IMAGE).

Parameters:

eventId - the event identifier

values - the event parameters

recordEventEnd

public static void recordEventEnd(int eventId,
                                  int... values)

Records the end of the execution of a MicroVG event. Call this method to trace the duration of an event previously record with one of the recordEventEnd(int, int...) method. This method should not be called for instantaneous events.

Parameters:

eventId - the "end" event identifier

values - the "end" event parameters

mapGraphicsContext

public static int mapGraphicsContext(ej.microui.display.MicroUIGraphicsContext gc)

Maps a graphics context to an event parameter.

Parameters:

gc - the graphics context to log

Returns:

the unique graphics context identifier

mapImage

public static int mapImage(MicroVGImage img)

Maps an image to an event parameter.

Parameters:

img - the image to log

Returns:

the unique image identifier
