		sampleFormat	format,
		sampleCount	start,
		size_t	len,
		bool	backward,

		sampleCount *	pNumWithinClips = `nullptr`
	)		const

inlineoverridevirtual

Retrieve samples of one of the channels from a sequence in a specified format

Parameters

format	sample format of the destination buffer
backward	retrieves samples from `start` (inclusive) to `start + len` if false, else from `start` (exclusive) to `start - len` in reverse order.

Returns: whether successful; if not, assume nothing about buffer contents

Implements WideSampleSequence.
