Constructor Detail

Build

protected Build(MethodDescription target,
                Map<?,Integer> registeredTargetIndices,
                StackManipulation methodInvocation,
                List<StackManipulation> parameterStackManipulations,
                StackManipulation terminatingStackManipulation)

Creates a new method binding.

Parameters:

target - The target method this binding represents.

registeredTargetIndices - A map of identification tokens to the indices of their binding parameters.

methodInvocation - A stack manipulation that represents the actual method invocation.

parameterStackManipulations - A list of manipulations that each represent the loading of a parameter value onto the operand stack.

terminatingStackManipulation - The stack manipulation that is applied after the method invocation.

Method Detail

isValid

public boolean isValid()

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.

getTargetParameterIndex

@MaybeNull
public Integer getTargetParameterIndex(Object parameterBindingToken)

Returns the target method's parameter index for a given parameter binding token.

A binding token can be any object that implements valid Object.hashCode() and Object.equals(Object) methods in order to look up a given binding. This way, two bindings can be evaluated of having performed a similar type of binding such that these bindings can be compared and a dominant binding can be identified by an MethodDelegationBinder.AmbiguityResolver. Furthermore, a binding is implicitly required to insure the uniqueness of such a parameter binding.

Specified by:

getTargetParameterIndex in interface MethodDelegationBinder.MethodBinding

Parameters:

parameterBindingToken - A token which is used to identify a specific unique binding for a given parameter of the target method.

Returns:

The target method's parameter index of this binding or null if no such argument binding was applied for this binding.

getTarget

public MethodDescription getTarget()

Returns the target method of the method binding attempt.

Specified by:

getTarget in interface MethodDelegationBinder.MethodBinding

Returns:

The target method to which the

apply

public StackManipulation.Size apply(MethodVisitor methodVisitor,
                                    Implementation.Context implementationContext)

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.

implementationContext - The context of the current implementation.

Returns:

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