Class SuperClassInvocationBenchmark

java.lang.Object

net.bytebuddy.benchmark.SuperClassInvocationBenchmark

public class SuperClassInvocationBenchmark
extends Object

This benchmark measures the invocation speed of stub method invocations. All classes implement ExampleClass and call this class's super method invocation. Since it is not possible to create a subclass with the JDK proxy utilities, the latter is omitted from the benchmark.

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.

Method Detail

setUp

public void setUp()
           throws Exception

Creates an instance for each code generation library. The classes are extracted from the ClassByExtensionBenchmark.

Throws:

Exception - Covers the exception declarations of the setup methods.

baseline

public void baseline(Blackhole blackHole)

Performs a benchmark for a casual class as a baseline.

Parameters:

blackHole - A black hole for avoiding JIT erasure.

benchmarkByteBuddyWithProxy

public void benchmarkByteBuddyWithProxy(Blackhole blackHole)

Performs a benchmark of a super method invocation using Byte Buddy. This benchmark uses an annotation-based approach which is more difficult to optimize by the JIT compiler.

Parameters:

blackHole - A black hole for avoiding JIT erasure.

benchmarkByteBuddyWithAccessor

public void benchmarkByteBuddyWithAccessor(Blackhole blackHole)

Performs a benchmark of a super method invocation using Byte Buddy. This benchmark also uses the annotation-based approach but creates delegation methods which do not require the creation of additional classes.

Parameters:

blackHole - A black hole for avoiding JIT erasure.

benchmarkByteBuddyWithPrefix

public void benchmarkByteBuddyWithPrefix(Blackhole blackHole)

Performs a benchmark of a super method invocation using Byte Buddy. This benchmark also uses the annotation-based approach but hard-codes the super method call subsequently to the method.

Parameters:

blackHole - A black hole for avoiding JIT erasure.

benchmarkByteBuddySpecialized

public void benchmarkByteBuddySpecialized(Blackhole blackHole)

Performs a benchmark of a super method invocation using Byte Buddy. This benchmark uses a specialized interception strategy which is easier to inline by the compiler.

Parameters:

blackHole - A black hole for avoiding JIT erasure.

benchmarkCglib

public void benchmarkCglib(Blackhole blackHole)

Performs a benchmark of a super method invocation using cglib.

Parameters:

blackHole - A black hole for avoiding JIT erasure.

benchmarkJavassist

public void benchmarkJavassist(Blackhole blackHole)

Performs a benchmark of a super method invocation using javassist.

Parameters:

blackHole - A black hole for avoiding JIT erasure.
