Package com.google.cloud.hadoop.util

Class TraceOperation

java.lang.Object

com.google.cloud.hadoop.util.TraceOperation

All Implemented Interfaces:

ITraceOperation, AutoCloseable

public class TraceOperation
extends Object
implements ITraceOperation

Helps trace a block of code.

Use TraceOperation.createRootWithLogging to setup tracing on a thread. Use TraceOperation.addToExistingTrace to add to the existing tracer. Use TraceOperation.getChildTrace to track operation which runs in another thread

NOTE: Ensure that close() is called on each of the operation. NOTE: This class is for internal use and can change without notice.
