Detailed Description

Same as RingBuffer, except that it uses the Wavetable mode for lost or late packets.

Constructor & Destructor Documentation

RingBufferWavetable::RingBufferWavetable	(	int	SlotSize,
		int	NumSlots
	)

inline

The class constructor.

Parameters

SlotSize	Size of one slot in bytes
NumSlots	Number of slots

virtual RingBufferWavetable::~RingBufferWavetable ( )

inlinevirtual

The class destructor.

virtual void RingBufferWavetable::setUnderrunReadSlot ( int8_t * ptrToReadSlot )

inlineprotectedvirtual

Sets the memory in the Read Slot when uderrun occurs. This loops as a wavetable in the last received packet.

Parameters

ptrToReadSlot Pointer to read slot from the RingBuffer

Reimplemented from RingBuffer.
