Chapter 22. Dynamic Plug-ins
Applications are often dynamic. New functions are added, old functions are removed, but the system keeps running. Equinox and Eclipse enable this kind of behavior and the RCP base plug-ins tolerate it, but the ability does not come free—you must follow certain practices to make the most of these scenarios.
This chapter discusses the unique challenges presented to plug-in writers as they attempt to handle the comings and goings of plug-ins in the environment. In particular, the following topics are covered:
• The notions of dynamic awareness and dynamic enablement
• Hyperbola as an example of an application requiring dynamic facilities
• Common dynamic plug-in scenarios
• Coding practices, mechanisms, and design approaches ...
