Class TimedBlock

java.lang.Object

org.graylog2.utilities.TimedBlock

All Implemented Interfaces:

AutoCloseable

public class TimedBlock
extends Object
implements AutoCloseable

Helper to time arbitrary blocks of Java code, especially useful for coarse one-off performance testing. This is not intended to be a silver bullet, but certainly more convenient than adding stopwatches all over the place. Use it like this:

     try (TimedBlock ignored = TimedBlock.timed("myBlock").aboveMillis(100).start()) {
         // code to time, will only print timing info if it took 100ms or more
     }
 

By default it will use its own logger to write timing information after the try-with-resources block exits.
