/**
 * Instances of this class serve as a focus point for configuration of the library's behavior and as an entry point
 * to any form of code generation using the library. For this purpose, Byte Buddy offers a fluent API which allows
 * for the step-wise generation of a new Java type. A type is generated either by:
 * 
    
 * 
  • Subclassing some type: A subclass - as the name suggests - extends another, existing Java type. Virtual
 * members of the generated type's super types can be overridden. Subclasses can also be interface extensions of one
 * or several interfaces.
    • 
 * 
  • Redefining a type: By redefining a type, it is not only possible to override virtual methods of the
 * redefined type but also to redefine existing methods. This way, it is also possible to change the behavior of
 * non-virtual methods and constructors of the redefined type.
    • 
 * 
  • Rebasing a type: Rebasing a type works similar to creating a subclass, i.e. any method being overridden
 * is still capable of invoking any original code of the rebased type. Any rebased method is however inlined into the
 * rebased type and any original code is preserved automatically. This way, the type's identity does not change.
    • 
 * 

 * Byte Buddy's API does not change when a type is rebased, redefined or subclassed. All types are created via the
 * {@link com.fitbur.bytebuddy.dynamic.DynamicType.Builder} interface. Byte Buddy's API is expressed by fully immutable
 * components and is therefore thread-safe. As a consequence, method calls must be chained for all of Byte Buddy's
 * component, e.g. a method call like the following has no effect:
 * 
 * ByteBuddy byteBuddy = new ByteBuddy();
 * byteBuddy.foo()

 * Instead, the following method chain is corrent use of the API:
 * 
 * ByteBuddy byteBuddy = new ByteBuddy().foo();

 * 

 * For the creation of Java agents, Byte Buddy offers a convenience API implemented by the
 * {@link com.fitbur.bytebuddy.agent.builder.AgentBuilder}. The API wraps a {@link ByteBuddy} instance and offers agent-specific
 * configuration opportunities by integrating against the {@link java.lang.instrument.Instrumentation} API.
 * 

 *
 * @see com.fitbur.bytebuddy.agent.builder.AgentBuilder
