proguard.evaluation.ReferenceTracingInvocationUnit

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).
