Class MethodDelegationBinder.ParameterBinding.Unique<T>

java.lang.Object

net.bytebuddy.instrumentation.method.bytecode.bind.MethodDelegationBinder.ParameterBinding.Unique<T>

Type Parameters:

T - The type of the identification token.

All Implemented Interfaces:

MethodDelegationBinder.ParameterBinding<T>, StackManipulation

Enclosing interface:

MethodDelegationBinder.ParameterBinding<T>

public static class MethodDelegationBinder.ParameterBinding.Unique<T>
extends Object
implements MethodDelegationBinder.ParameterBinding<T>

A uniquely identifiable parameter binding for a target method. Such bindings are usually later processed by a MethodDelegationBinder.AmbiguityResolver in order to resolve binding conflicts between several bindable target methods to the same source method.

Constructor Detail

Unique

public Unique(StackManipulation delegate,
              T identificationToken)

Creates a new unique parameter binding representant.

Parameters:

delegate - The stack manipulation that loads the argument for this parameter onto the operand stack.

identificationToken - The token used for identifying this parameter binding.

Method Detail

of

public static <S> MethodDelegationBinder.ParameterBinding.Unique<S> of(StackManipulation delegate,
                                                                       S identificationToken)

A factory method for creating a unique binding that infers the tokens type.

Type Parameters:

S - The type of the identification token.

Parameters:

delegate - The stack manipulation delegate.

identificationToken - The identification token.

Returns:

A new instance representing this unique binding.

getIdentificationToken

public T getIdentificationToken()

Description copied from interface: MethodDelegationBinder.ParameterBinding

Returns an identification token for this binding.

Specified by:

getIdentificationToken in interface MethodDelegationBinder.ParameterBinding<T>

Returns:

An identification token unique to this binding.

isValid

public boolean isValid()

Description copied from interface: StackManipulation

Determines if this stack manipulation is valid.

Specified by:

isValid in interface StackManipulation

Returns:

If false, this manipulation cannot be applied and should throw an exception.

apply

public StackManipulation.Size apply(org.objectweb.asm.MethodVisitor methodVisitor,
                                    Instrumentation.Context instrumentationContext)

Description copied from interface: StackManipulation

Applies the stack manipulation that is described by this instance.

Specified by:

apply in interface StackManipulation

Parameters:

methodVisitor - The method visitor used to write the method implementation to.

instrumentationContext - The context of the current instrumentation.

Returns:

The changes to the size of the operand stack that are implied by this stack manipulation.
