Class StubInvocationBenchmark

java.lang.Object

net.bytebuddy.benchmark.StubInvocationBenchmark

public class StubInvocationBenchmark
extends Object

This benchmark measures the invocation speed of stub method invocations. All classes implement ExampleInterface and implement all methods to return the return type's default value, independently of the arguments.

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.
