								Calls a redefined/inherited definition for a message. Normally only used in the body of a predicate definition for the message. Predicate should match a public or protected predicate of < a  class = "glossary"  title = "Go to glossary definition"  href = "../../glossary.html#self" > self< / a >  or be within the scope of < a  class = "glossary"  title = "Go to glossary definition"  href = "../../glossary.html#this" > this< / a > .
