Notes on Evolving APIs in Java 5
Revision as of 18:25, 17 October 2006 by Unnamed Poltroon (Talk)
This page captures notes and discussions about API evolution guidelines in Java 5. The eventual output of these notes will be an update to the Evolving Java-based APIs document. General rule: the left-most bound of a generic type within API can never be changed. Bounds other than the left-most bound can be weakened without sacrificing compatibility.
Generics
Generics do not exist in the binary form of a class. Thus, binary compatibility of a class containing generics is reduced to compatibility of the [erasure] of the generic types.
