Class MethodDescriptor

  • public class MethodDescriptor
extends java.lang.Object
    Represents the descriptor that is part of a MethodSignature. A descriptor consists of parameter types and return type of a method, e.g. "()V" for a void method with no parameters, or "(II)B" for a method that takes two integers and returns a boolean. Read more about this topic in ยง4.3.3 of the JVM specification.
