Interface Scope

All Superinterfaces:

AutoCloseable, Closeable

public interface Scope
extends Closeable

A Scope formalizes the activation and deactivation of a Span, usually from a CPU standpoint.

Many times a Span will be extant (in that Span.finish() has not been called) despite being in a non-runnable state from a CPU/scheduler standpoint. For instance, a Span representing the client side of an RPC will be unfinished but blocked on IO while the RPC is still outstanding. A Scope defines when a given Span is scheduled and on the path.
