Examples of org.apache.hivemind.service.ClassFab.addMethod()

org.apache.hivemind.service.ClassFab.addMethod()
Adds a method. The method is a public instance method. @return a method fabricator, used to add catch handlers. @param modifiers Modifiers for the method (see {@link java.lang.reflect.Modifier}). @param signature defines the name, return type, parameters and exceptions thrown @param body The body of the method. @throws org.apache.hivemind.ApplicationRuntimeException if a method with that signature has alreadybeen added, or if there is a Javassist compilation error
