◆ CreateDiscreteSequence()

virtual bool imeas::IDiscreteDataSequence::CreateDiscreteSequence	(	int	samplesCount,
		istd::COptMemory &&	data,
		int	sampleDiff,
		int	channelDiff,
		int	sampleDepth,
		int	channelsCount = 1,
		std::unique_ptr< const IDataSequenceInfo > &&	infoPtr = nullptr )

pure virtual

Create container for sample sequence using external samples buffer.

Parameters

samplesCount	number of samples.
data	external buffer.
sampleDiff	address difference between next and previos sample. If it equals 0, the value will be taken from number of samples, number of channels and `channelDiff`.
channelDiff	address difference between next and previos sample. If it equals 0, the value will be calculated from number of bits per single sample.
sampleDepth	number of bits used for representation of a single sample.
channelsCount	number of channels.
infoPtr	sequence info object.
