Class TargetMethodAnnotationDrivenBinder.ParameterBinder.ForFixedValue<S extends Annotation>

java.lang.Object

net.bytebuddy.implementation.bind.annotation.TargetMethodAnnotationDrivenBinder.ParameterBinder.ForFixedValue<S>

Type Parameters:

S - The bound annotation's type.

All Implemented Interfaces:

TargetMethodAnnotationDrivenBinder.ParameterBinder<S>

Direct Known Subclasses:

TargetMethodAnnotationDrivenBinder.ParameterBinder.ForFixedValue.OfConstant

Enclosing interface:

TargetMethodAnnotationDrivenBinder.ParameterBinder<T extends Annotation>

public abstract static class TargetMethodAnnotationDrivenBinder.ParameterBinder.ForFixedValue<S extends Annotation>
extends Object
implements TargetMethodAnnotationDrivenBinder.ParameterBinder<S>

Implements a parameter binder that binds a fixed value to a parameter with a given annotation.

This binder is only capable to store values that can either be expressed as Java byte code or as a constant pool value. This includes primitive types, String values, Class values which can also be expressed as TypeDescription instances or method handles and method types for classes of a version at least of Java 7. The latter instances can also be expressed as unloaded JavaConstant representations.

Important: When supplying a method handle or a method type, all types that are implied must be visible to the instrumented type or an IllegalAccessException will be thrown at runtime.

                                                       Assigner.Typing typing)

Creates a parameter binding for the given target parameter.

Specified by:

bind in interface TargetMethodAnnotationDrivenBinder.ParameterBinder<S extends Annotation>

Parameters:

annotation - The annotation that was cause for the delegation to this argument binder.

source - The intercepted source method.

target - Tge target parameter that is subject to be bound to intercepting the source method.

implementationTarget - The target of the current implementation that is subject to this binding.

assigner - An assigner that can be used for applying the binding.

typing - The typing to apply.

Returns:

A parameter binding for the requested target method parameter.

bind

@MaybeNull
protected abstract Object bind(AnnotationDescription.Loadable<S> annotation,
                                          MethodDescription source,
                                          ParameterDescription target)

Resolves a value for the given annotation on a parameter that is processed by a MethodDelegation.

Parameters:

annotation - The annotation that triggered this binding.

source - The method for which a delegation is currently bound.

target - The parameter for which a value is bound.

Returns:

The constant pool value that is bound to this parameter or null for binding this value.
