## bind

bind( Object src, String srcProp, Object dst, String dstProp ) → void

binds two bean properties together. Bindings are bidirectional, but the initial copy is from src to dst. In MVC terms, src should be the model and dst should be a view. The properties must fire property change events for the binding mechanism to work. As of v2014a_10, if the src is a DomNode and a child of the application, then use dom.getController().bind so that the vap will contain the binding. Example:

>      model= getApplicationModel()
>      bind( model.getPlotDefaults(), "title", model.getPlotDefaults().getXAxis(), "label" )

### Parameters

src - java bean such as model.getPlotDefaults()

## dumpToDas2Stream

dumpToDas2Stream( QDataSet ds, boolean ascii ) → void

serializes the dataset to a das2stream, a well-documented, open, streaming data format. (that's a joke.) Das2Streams are the legacy stream format used by the Plasma Wave Groups's server, and can serialize a limited set of QDataSets. QStreams were introduced to allow streaming of any QDataSet, see dumpToQStream. Currently, to keep the channel open, the stream is created in a buffer and then the buffer is sent. TODO: write a stream-producing code that doesn't close the output stream. (TODO: does it still do this?)

### Parameters

ds - a QDataSet
ascii - use ascii transfer types, otherwise binary are used.
