Detailed Description

Reads raw samples from an imput stream, (ie a file).

Constructor & Destructor Documentation

template<class Scalar >

sdr::StreamSource< Scalar >::StreamSource	(	std::istream &	stream,
		double	sample_rate = `1`,
		size_t	buffersize = `1024`
	)

inline

Constructs a raw input source.

template<class Scalar >

void sdr::StreamSource< Scalar >::next ( )

inline

Reads the next chunk.

This function might be connected to the idle event of the Queue, then a new chunk gets read once all processing has been performed.

template<class Scalar >

Buffer<Scalar> sdr::StreamSource< Scalar >::_buffer

protected

The output buffer.

template<class Scalar >

std::istream& sdr::StreamSource< Scalar >::_stream

protected

The input stream.
