boolean org.nees.rbnb.DataVideoSink.connect (  String  server, String  sinkName )

Connect to the RBNB server with two sinks one for a data stream and one for a coordinated video stream. Returns: boolean connected true when susessfully connected otherwise false Definition at line 387 of file DataVideoSink.java. References org.nees.rbnb.DataVideoSink.connect().

void org.nees.rbnb.DataVideoSink.fetchData (  String  dataSourcePath, double  startTime, double  duration, String  requestType )

Fetch both the data and the time values for a single channel,. Parameters: dataSourcePath  (String) the RBNB path to the source for the data itmes startTime  (double) the start time in seconds for the event stream desired duration  (double) the duration in secodns for the event stream desired fetchType  (String) the RBNB fetch type See also: the Request method of the RBNB Sink class Definition at line 430 of file DataVideoSink.java.

void org.nees.rbnb.DataVideoSink.fetchData (  String  dataSourcePath, double  startTime, double  duration )

Fetches data according to the values supplied. Parameters: startTime  (double) the start time in seconds for the event stream desired duration  (double) the duration in secodns for the event stream desired Definition at line 417 of file DataVideoSink.java.

double [] org.nees.rbnb.DataVideoSink.getDataArray (   )

Returns the arrat of data items. Returns: double[] dataArray Definition at line 535 of file DataVideoSink.java.

int org.nees.rbnb.DataVideoSink.getNumberOfItems (   )

Returns the number of items fetched by the last fetch request. Returns: Definition at line 519 of file DataVideoSink.java.

byte [] org.nees.rbnb.DataVideoSink.getRBNBImage (  String  videoSourcePath, double  videoTime )  throws SAPIException

Get the "nearest" image after the time specified. Throws exceptions if the requests times out or if the data is not availavbe. Parameters: videoSourcePath  (String) the RBNB path of the video source (ie "InterestingVideoSource/Video.jpg") videoTime  (double) the RBNB time stamp to start from Returns: byte[] the "nearest" image after the time specified Exceptions: SAPIException  when the request times out or when request channel is unavailable.

double [] org.nees.rbnb.DataVideoSink.getTimeArray (   )

Returns the array of times corresponding to the data items fetched. Returns: double timeArray Definition at line 527 of file DataVideoSink.java.

void org.nees.rbnb.DataVideoSink.makeMovie (  float  frameRate, String  oURL, String  videoSourcePath, int  dataItemsToSkip )  throws Exception

Make a movie (extension *.mov) of the images that corresond to the times currently in the time array (from the last data fetch). The images for the movie are from the image source specified by videoSourcePath. The movie is written to disk at the file specified by oURL (ie "file:/tmp/movie.mov). The items in TimeArray are treated as time marks for the images, intermitent time items can be skipped, using dataItemsToSkip. To find a image for every time stamp in timeArray, set dataItemsToSkip to zero (0). Setting dataItemsToSkip to 9 would use timeArray[0], timeArray[10], timeArray[20], etc. This throws exceptions when the movie can not be built or written. Parameters: frameRate  (float) the frame rate, in frames per second oURL  videoSourcePath  dataItemsToSkip  Exceptions: Exception  Definition at line 490 of file DataVideoSink.java.
