Detailed Description

template<class TImage>
class otb::RAMDrivenAdaptativeStreamingManager< TImage >

This class computes the divisions needed to stream an image according to the input image tiling scheme and a user-defined available RAM.

This streaming manager uses the TileHint from the MetaDataDictionary to find out the tiling scheme of the input file if available.

You can use SetAvailableRAMInMB to set the available RAM. An estimation of the pipeline memory print will be done, and the number of divisions will then be computed to fit the available RAM.
