An implementation is responsible for implementing methods of a dynamically created type as byte code. An
implementation is applied in two stages:

The implementation is able to prepare an instrumented type by adding fields and/or helper methods that are required for the methods implemented by this implementation. Furthermore, LoadedTypeInitializers and byte code for the type initializer can be registered for the instrumented type.
Any implementation is required to supply a byte code appender that is responsible for providing the byte code
to the instrumented methods that were delegated to this implementation. This byte code appender is also
be responsible for providing implementations for the methods added in step 1.

 
 An implementation should provide meaningful implementations of both Object.equals(Object) and Object.hashCode() if it wants to avoid to be used twice within the creation of a dynamic type. For two equal implementations only one will be applied on the creation of a dynamic type. /**

Params:	methodDescription – The method that represents the special method invocation. typeDescription – The type on which the method should be invoked on by an `INVOKESPECIAL` invocation.
Returns:	A special method invocation representing a legal invocation if the method can be invoked specially on the target type or an illegal invocation if this is not possible.
Params:	token – A token of the method that is to be invoked as a super method.
Returns:	The corresponding special method invocation which might be illegal if the requested invocation is not legal.

Returns:	The corresponding special method invocation which might be illegal if the requested invocation is not legal.
Params:	token – The method token representing the method to be invoked.
Returns:	A special method invocation for a method representing the method token.
Params:	instrumentedType – The instrumented type. methodGraph – A method graph of the instrumented type. classFileVersion – The type's class file version.
Returns:	An implementation target for the instrumented type.
Params:	classFileVersion – The class file version to resolve for.
Returns:	A suitable default method invocation mode.
Params:	node – The node representing the default method call. targetType – The target type defining the default method.
Returns:	A suitable special method invocation.
Params:	auxiliaryType – The auxiliary type that is required for the current implementation.
Returns:	A description of the registered auxiliary type.
Params:	instrumentedType – The description of the type that is currently subject of creation. auxiliaryTypeNamingStrategy – The naming strategy for naming an auxiliary type. typeInitializer – The type initializer of the created instrumented type. classFileVersion – The class file version of the created class. auxiliaryClassFileVersion – The class file version of any auxiliary classes.
Returns:	An implementation context in its extractable view.
Params:	fieldDescription – A static field in which the value is to be stored.
Returns:	A byte code appender that represents this storage.
Params:	accessType – The access type to enforce.
Returns:	A new version of this delegation record with the minimal implied visibility.
