所有已实现的接口:

ConstantVisitor, ParameterVisitor, InvocationUnit
```
public class ReferenceTracingInvocationUnit
extends SimplifiedInvocationUnit
```
This InvocationUnit tags reference values of retrieved fields, passed method parameters, method return values, and caught exceptions, so they can be traced throughout the execution of a method. The tags are instruction offsets or parameter indices (not parameter offsets).

`protected void`	`applySideEffects(Clazz clazz, AnyMethodrefConstant methodrefConstant, java.lang.String type)`
`void`	`enterExceptionHandler(Clazz clazz, Method method, CodeAttribute codeAttribute, int offset, int catchType, Stack stack)`	Sets up the given stack for entering the given exception handler.
`Value`	`getExceptionValue(Clazz clazz, ClassConstant catchClassConstant)`	Returns the value of the specified exception.
`Value`	`getFieldClassValue(Clazz clazz, FieldrefConstant fieldrefConstant, java.lang.String type)`	Returns the class though which the specified field is accessed.
`Value`	`getFieldValue(Clazz clazz, FieldrefConstant fieldrefConstant, java.lang.String type)`	Returns the value of the specified field.
`Value`	`getMethodParameterValue(Clazz clazz, Method method, int parameterIndex, java.lang.String type, Clazz referencedClass)`	Returns the value of the specified method parameter.
`Value`	`getMethodReturnValue(Clazz clazz, AnyMethodrefConstant anyMethodrefConstant, java.lang.String type)`	Returns the return value of the specified method.
`Value`	`getMethodReturnValue(Clazz clazz, InvokeDynamicConstant invokeDynamicConstant, java.lang.String type)`	Returns the return value of the specified method.
`void`	`invokeMember(Clazz clazz, Method method, CodeAttribute codeAttribute, int offset, ConstantInstruction constantInstruction, Stack stack, Variables variables)`	Updates the given stack corresponding to the execution of the given field or method reference instruction.
`protected boolean`	`methodMayHaveSideEffects(Clazz clazz, AnyMethodrefConstant anyMethodrefConstant, java.lang.String returnType)`	Returns true if the method itself can modify the stack/variables and therefore needs to be executed even if it returns void.

`void`	`setFieldValue(Clazz clazz, FieldrefConstant fieldrefConstant, Value value)`	Sets the value of the specified field.
`void`	`setMethodParameterValue(Clazz clazz, AnyMethodrefConstant anyMethodrefConstant, int parameterIndex, Value value)`	Sets the value of the specified method parameter.
`void`	`setMethodReturnValue(Clazz clazz, Method method, Value value)`	Sets the return value of the specified method.
`protected Value`	`trace(Value value, int trace)`	Sets or replaces the trace value on a given value, if it's a reference value, returning the result.
`protected Value`	`trace(Value value, InstructionOffsetValue traceValue)`	Sets or replaces the trace value on a given value, returning the result.
`void`	`visitAnyMethodrefConstant(Clazz clazz, AnyMethodrefConstant anyMethodrefConstant)`	Visits any RefConstant instance.
