Class TrivialClassCreationBenchmark

java.lang.Object

net.bytebuddy.benchmark.TrivialClassCreationBenchmark

Direct Known Subclasses:

TrivialClassCreationBenchmark_jmhType_B1

public class TrivialClassCreationBenchmark
extends Object

A benchmark for creating plain subclasses of Object that do not override any methods. This benchmark intends to measure the general overhead of each library.

Note that this class defines all values that are accessed by benchmark methods as instance fields. This way, the JIT compiler's capability of constant folding is limited in order to produce more comparable test results.
