Constructs a new LocalVariableAnnotationNode. Subclasses must not use this constructor. Instead, they must use the LocalVariableAnnotationNode(int, TypePath, LabelNode[], LabelNode[], int[], String) version.
Params:
  • typeRef – a reference to the annotated type. See TypeReference.
  • typePath – the path to the annotated type argument, wildcard bound, array element type, or static inner type within 'typeRef'. May be null if the annotation targets 'typeRef' as a whole.
  • start – the fist instructions corresponding to the continuous ranges that make the scope of this local variable (inclusive).
  • end – the last instructions corresponding to the continuous ranges that make the scope of this local variable (exclusive). This array must have the same size as the 'start' array.
  • index – the local variable's index in each range. This array must have the same size as the 'start' array.
  • desc – the class descriptor of the annotation class.
