Detailed Description

template<class T>
class shogun::CStreamingFileFromSimpleFeatures< T >

Class CStreamingFileFromSimpleFeatures is a derived class of CStreamingFile which creates an input source for the online framework from a CSimpleFeatures object.

This kind of input is seekable, and hence can be used for making multiple passes over data.

It is useful for testing/comparison purposes.
