Method Summary

Modifier and Type	Method and Description
void	visit(String flagName, boolean flagValue)
void	visit(String fieldName, HotLoopCallee value)
void	visit(String fieldName, Object value)
void	visit(String key, String runtimeShape) To be called from HotLoopCallee.inspectRuntimeShape(RuntimeShapeInspector) with something, that is important to ensure monomorphism and predictable branch taking in hot loops, but doesn't apply to other visit() methods in RuntimeShapeInspector.

           @Nullable
           HotLoopCallee value)

visit

void visit(String key,
           String runtimeShape)

To be called from HotLoopCallee.inspectRuntimeShape(RuntimeShapeInspector) with something, that is important to ensure monomorphism and predictable branch taking in hot loops, but doesn't apply to other visit() methods in RuntimeShapeInspector. For example, BitmapOffset.inspectRuntimeShape(io.druid.query.monomorphicprocessing.RuntimeShapeInspector) reports bitmap population via this method, to ensure predictable branch taking inside Bitmap's iterators.
