    public class TypeProxy
    extends java.lang.Object
    implements AuxiliaryType
    A type proxy creates accessor methods for all overridable methods of a given type by subclassing the given type and delegating all method calls to accessor methods of the instrumented type it was created for.

        public TypeProxy​(TypeDescription proxiedType,
                         Implementation.Target implementationTarget,
                         TypeProxy.InvocationFactory invocationFactory,

        Creates a new type proxy.
        Parameters:

        implementationTarget - The implementation target this type proxy is created for.
        invocationFactory - The invocation factory for creating special method invocations.
        ignoreFinalizer - true if any finalizer methods should be ignored for proxying.
        serializableProxy - Determines if the proxy should be serializable.

      • make

        public DynamicType make​(java.lang.String auxiliaryTypeName,
                                ClassFileVersion classFileVersion,
                                MethodAccessorFactory methodAccessorFactory)
        Creates a new auxiliary type.
        Specified by:
        make in interface AuxiliaryType
        Parameters:
        auxiliaryTypeName - The fully qualified binary name for this auxiliary type. The type should be in the same package than the instrumented type this auxiliary type is providing services to in order to allow package-private access.
        classFileVersion - The class file version the auxiliary class should be written in.
        methodAccessorFactory - A factory for accessor methods.
        Returns:
        A dynamically created type representing this auxiliary type.
