Interface TracerConverter

public interface TracerConverter

Function converting an existing Tracer.

This can be useful for wrapping tracers:

 public final class FooWrapperConverter implements TracerConverter {
     public Tracer convert(Tracer existingTracer) {
         return new FooTracerWrapper(existingTracer);
     }
 }
 

If there are multiple TracerConverter implementations resolved, they will be applied in the order of their @Priority annotation:

1. First, non-negative priority is applied in natural order (e.g. 0, 1, 2, ...).
2. Next, objects without @Priority annotation are applied by assigning a default priority of Integer.MAX_VALUE.
3. Finally, negative priority is applied in reverse-natural order (e.g. -1, -2, -3, ...).

The order of objects with equal (implicit) priority is undefined.
