Detailed Description
template<typename ElemType, typename ReportTraits, typename BubbleTraits = BubbleTraitsAdaptor<ElemType>>
class Minor::SelfStallingPipeline< ElemType, ReportTraits, BubbleTraits >
A pipeline simulating class that will stall (not advance when advance() is called) if a non-bubble value lies at the far end of the pipeline.
The user can clear the stall before calling advance to unstall the pipeline.

Member Function Documentation
◆ advance()
|
inline |
Try to advance the pipeline.
If we're stalled, don't advance. If we're not stalled, advance then check to see if we become stalled (a non-bubble at the end of the pipe)

◆ isPopable()

There's data (not a bubble) at the end of the pipe.

◆ push()
|
inline |
Write an element to the back of the pipeline.
This doesn't cause the pipeline to advance until advance is called. Pushing twice without advance-ing will just cause an overwrite of the last push's data.
