Summary
Defines the state of the processing pipe.
Unit
SignalTools
Declaration
TPipeState = (pipeOK, pipeStream, pipeEnd, pipeBuffer);
| Value | Description |
|---|
| pipeOK | The connected component has returned a valid block of data. |
| pipeEnd | The connected component has not returned a valid block of data, because there is no more data to be processed. The connected components have not recalucated (no data). The processing can stop. |
| pipeStream | The buffer has not returned a new block of data, but the stream has not ended yet. All components in the chain before the buffer have been recalculated. |
| pipeBuffer | The connected component has returned a valid block of data, but it came from the buffer and the update request did not go beyond the buffer component. All components from the buffer on have recalculated. All components in the chain before the buffer have not yet recalculated. |
Description
There are four possible states. Two of them, pipeStream and pipeBuffer, occure only, if TSignalBuffer component is connected in the processing chain.
