protected Build(MethodDescription target, java.util.Map<?,java.lang.Integer> registeredTargetIndices, StackManipulation methodInvocation, java.util.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 interfaceStackManipulation
- Returns:
- If
false
, this manipulation cannot be applied and should throw an exception.
-
getTargetParameterIndex
public java.lang.Integer getTargetParameterIndex(java.lang.Object parameterBindingToken)
Returns the target method's parameter index for a given parameter binding token.Object.hashCode()
andObject.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 anMethodDelegationBinder.AmbiguityResolver
. Furthermore, a binding is implicitly required to insure the uniqueness of such a parameter binding.- Specified by:
getTargetParameterIndex
in interfaceMethodDelegationBinder.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 interfaceMethodDelegationBinder.MethodBinding
- Returns:
- The target method to which the
-
apply
public StackManipulation.Size apply(org.objectweb.asm.MethodVisitor methodVisitor, Implementation.Context implementationContext)
Applies the stack manipulation that is described by this instance.- Specified by:
apply
in interfaceStackManipulation
- 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.
