Detailed Description

Extension of ProcessData.

Helps setting up the buffers for the process data structure for a component. When the prepare method is called with bufferSamples != 0 the buffer management is handled by this class. Otherwise the buffers need to be setup explicitly.

If bufferSamples is not null buffers will be created.

unprepare()

void unprepare

(

)

Remove bus buffers.

setChannelBuffers() [1/2]

bool setChannelBuffers ( BusDirection dir, int32 busIndex, Sample32 * sampleBuffer )

inline

Sets one sample buffer for all channels inside a bus.
