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()

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.

getTargetParameterIndex

public Integer getTargetParameterIndex(Object parameterBindingToken)

Description copied from interface: MethodDelegationBinder.MethodBinding

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()

Description copied from interface: MethodDelegationBinder.MethodBinding

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(org.objectweb.asm.MethodVisitor methodVisitor,
                                    Implementation.Context implementationContext)

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.

implementationContext - The context of the current implementation.

Returns:

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