ClassByImplementationBenchmark (Byte Buddy benchmarks 1.14.0 API)

java.lang.Object
- net.bytebuddy.benchmark.ClassByImplementationBenchmark

```
public class ClassByImplementationBenchmark
extends Object
```
This benchmark dynamically creates a class which implements ExampleInterface which overrides all methods to invoke the direct super class's implementation. The benchmark furthermore creates an instance of this class since some code generation frameworks rely on this property.

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.

- Field Detail
  - BASE_CLASS
```
public static final Class<? extends ExampleInterface> BASE_CLASS
```
    The base class to be subclassed in all benchmarks.
  - DEFAULT_REFERENCE_VALUE
```
@AlwaysNull
public static final String DEFAULT_REFERENCE_VALUE
```
    The default reference value. By defining the default reference value as a string type instead of as an object type, the field is inlined by the compiler, similar to the primitive values.
  - DEFAULT_BOOLEAN_VALUE
```
public static final boolean DEFAULT_BOOLEAN_VALUE
```
    The default boolean value.

```
public static final byte DEFAULT_BYTE_VALUE
```
    The default byte value.

```
public static final short DEFAULT_SHORT_VALUE
```
    The default short value.

```
public static final char DEFAULT_CHAR_VALUE
```
    The default char value.

  - DEFAULT_INT_VALUE
```
public static final int DEFAULT_INT_VALUE
```
    The default int value.

  - baseline
```
public ExampleInterface baseline()
```
    Creates a baseline for the benchmark.

  - benchmarkByteBuddy
```
public ExampleInterface benchmarkByteBuddy()
                                    throws Exception
```
    Performs a benchmark of an interface implementation using Byte Buddy.
    
    Returns:
    
    The created instance, in order to avoid JIT removal.
    
    Throws:
    
    Exception - If the reflective invocation causes an exception.
  - benchmarkByteBuddyWithTypePool
```
public ExampleInterface benchmarkByteBuddyWithTypePool()
                                                throws Exception
```
    Performs a benchmark of an interface implementation using Byte Buddy. This benchmark uses a type pool to compare against usage of the reflection API.
    
    Returns:
    
    The created instance, in order to avoid JIT removal.
    
    Throws:
    
    Exception - If the reflective invocation causes an exception.
  - benchmarkCglib
```
public ExampleInterface benchmarkCglib()
```
    Performs a benchmark of an interface implementation using cglib.
    
    Returns:
    
    The created instance, in order to avoid JIT removal.

    Returns:
    
    The created instance, in order to avoid JIT removal.
    
    Throws:
    
    Exception - If the reflective invocation causes an exception.
  - benchmarkJdkProxy
```
