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.public MethodDescription registerAccessorFor(Implementation.SpecialMethodInvocation specialMethodInvocation)
AuxiliaryType.MethodAccessorFactoryImplementation.SpecialMethodInvocation which cannot itself be
triggered invoked directly from outside a type. The method is registered on the instrumented type
with package-private visibility, similarly to a Java compiler's accessor methods.registerAccessorFor in interface AuxiliaryType.MethodAccessorFactoryspecialMethodInvocation - The special method invocation.public MethodDescription registerGetterFor(FieldDescription fieldDescription)
AuxiliaryType.MethodAccessorFactoryFieldDescription which might
itself not be accessible from outside the class. The returned getter method defines the field type as
its return type, does not take any arguments and is of package-private visibility, similarly to the Java
compiler's accessor methods. If the field is static, this accessor method is also static.registerGetterFor in interface AuxiliaryType.MethodAccessorFactoryfieldDescription - The field which is to be accessed.public MethodDescription registerSetterFor(FieldDescription fieldDescription)
AuxiliaryType.MethodAccessorFactoryFieldDescription which might
itself not be accessible from outside the class. The returned setter method defines the field type as
its only argument type, returns void and is of package-private visibility, similarly to the Java
compiler's accessor methods. If the field is static, this accessor method is also static.registerSetterFor in interface AuxiliaryType.MethodAccessorFactoryfieldDescription - The field which is to be accessed.public TypeDescription register(AuxiliaryType auxiliaryType)

Implementation.Contextprivate, final and static field.
By caching values, expensive instance creations can be avoided and object identity can be preserved.
The field is initiated in a generated class's static initializer.cache in interface Implementation.ContextfieldValue - A stack manipulation for creating the value that is to be cached in a static field.
After executing the stack manipulation, exactly one value must be put onto the operand
stack which is assignable to the given fieldType.fieldType - The type of the field for storing the cached value. This field's type determines the value
that is put onto the operand stack by this method's returned stack manipulation.public void drain(org.objectweb.asm.ClassVisitor classVisitor,

Implementation.Context.ExtractableView.InjectedCode injectedCode)
Implementation.Context.ExtractableViewImplementation.Context
to the provided class visitor. This contains any fields for value caching, any accessor method and it
writes the type initializer. The type initializer must therefore never be written manually.drain in interface Implementation.Context.ExtractableViewclassVisitor - The class visitor to which the extractable view is to be written.methodPool - A method pool which is queried for any user code to add to the type initializer.injectedCode - Potential code that is to be injected into the type initializer.Copyright © 2014–2015.
