Method Summary

Modifier and Type	Method	Description
void	visit(String flagName, boolean flagValue)
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.

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(org.apache.druid.query.monomorphicprocessing.RuntimeShapeInspector) reports bitmap population via this method, to ensure predictable branch taking inside Bitmap's iterators.
