[jira] Created: (RVM-594) Naming of MM_Interface

Naming of MM_Interface
----------------------

                 Key: RVM-594
                 URL: http://jira.codehaus.org/browse/RVM-594
             Project: RVM
          Issue Type: Wish
          Components: MMTk
            Reporter: Ian Rogers
            Assignee: David Grove
             Fix For: 3.0


the interface between Jikes RVM and MMTk is in different places:

org.jikesrvm.memorymanagers.mminterface.*
org.jikesrvm.mm.mmtk.*

the main interface is called MM_Interface. The memory managers package or mm package only ever contains mmtk. I suggest that the two packages above become:

org.jikesrvm.mmtk

The MM_ prefix looks redundant and similar to the now demised VM_ and OPT_ prefixes. Obviously a better name than Interface would be needed for MM_Interface.

Daniel Frampton commented on RVM-594:
-------------------------------------

The current state of things is not entirely clear, and not necessarily perfectly organised around the idea, but there are some clear distinctions here:

- The interface from MMTk to *any* VM - org.mmtk.vm.*. This is implemented for JikesRVM in org.jikesrvm.mm.mmtk.*

- The interface from JikesRVM to *any* MM. This is the set of methods in MM_Interface and the constants in MM_Constants. As MMTk is currently the only memory manager this is a little bit artificial, but the desire is to keep it separate.

It might be possible to have MM_Interface in org.jikesrvm.mm (possibly renamed to just be MM or MemoryManager) and then have the rest of the implementation in org.jikesrvm.mm.mmtk.
