Examples of org.apache.tapestry.services.MethodSignature

org.apache.tapestry.services.MethodSignature
A representation of a method signature, which consists of its name, modifiers (primarily, visibility), return type, parameter types, and declared exception types.
Types are stored as class names (or primitive names) because the MethodSignature is often used in situations where the actual class has not been loaded yet. When classes are already loaded (such as, for use with {@link org.apache.hivemind.service.ClassFab}), then a different implementation with the same name, {@link org.apache.tapestry.ioc.services.MethodSignature} is used.
