Detailed Description

template<class TImage>
class otb::StreamingManager< TImage >

This class handles the streaming process used in the writers implementation.

The streaming mode can be chosen with either SetStrippedRAMStreamingMode, SetStrippedNumberOfLinesStreamingMode, SetTiledRAMStreamingMode, or SetTiledTileDimensionStreamingMode.

Then, PrepareStreaming must be called so that the stream type and dimensions are computed This involves passing the actual DataObject who will be written, since it will be used during memory estimation for some specific streaming modes.

After PrepareStreaming has been called, the actual number of splits and streaming mode which will be used can be retrieved with GetStreamingMode and GetNumberOfSplits. The different splits can be retrieved with GetSplit
