Examples of org.apache.tapestry5.services.TransformMethodSignature

org.apache.tapestry5.services.TransformMethodSignature
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 signature is used with {@link ClassTransformation}(which operates on as-yet unloaded classes).
