  • All Implemented Interfaces:
    Comparable<MethodInfo>
    public class MethodInfo
extends Object
implements Comparable<MethodInfo>
    Holds metadata about methods of a class encountered during a scan. All values are taken directly out of the classfile for the class.

      • getTypeDescriptor

        public MethodTypeSignature getTypeDescriptor()
        Returns the parsed type descriptor for the method, which will not include type parameters. If you need generic type parameters, call getTypeSignature() instead.
