Trivial
protected Trivial(TypeDescription instrumentedType, MethodDescription instrumentedMethod, List<? extends TypeDescription> latentTypes, boolean expandFrames) Creates a new stack map frame handler that applies a trivial translation for the instrumented method's stack map frames.- Parameters:
instrumentedType
- The instrumented type.instrumentedMethod
- The instrumented method.latentTypes
- A list of virtual arguments that are available after the enter advice method is executed.expandFrames
-true
if the meta data handler is expected to expand its frames.
