    1717To provide an interface to a streaming data source in a convenient manner for RasterIO operations within GDAL and to expose this interface via swig.

    19 Note this RFC originally explored using an Observer pattern as per implementations in Java [http://java.sun.com/j2se/1.4.2/docs/api/javax/imageio/event/IIOReadUpdateListener.html imageio update] but after detailed discussions with [http://thread.gmane.org/gmane.comp.gis.gdal.devel/16409/focus=16630 Tamas Szekeres, Even Rouault,Adam Nowacki and Frank Warmerdam] a simpler interface is proposed to reduce the potential for problems by having the callback implemented by another thread.
