The Gemstone port

The origin of the code is VisualWorks and the target is Gemstone.

There are a number of possible approaches:

• fileOut VW XML format
  • no XML reader available?
  • nicely extensible with custom tags
  • todo
    • extend in VW
    • write an XML loader in Gemstone
    • interpret in GS
• fileOut30 ST80 chunk format
  • may load with Monticello?
  • looses namespace and pundle infos
  • todo
    • mangle in VW
    • load with Monticello
• fileOut GS Topaz input format
  • need to write a writer for this format
  • todo
    • writer in VW
• fileout Values
  • add transfer values
  • nicely extensible
  • todo
    • define transfer values in VW and GS (same)
    • interpret in GS

Not considered

• Using GemBuilder for Gemstone (GBS)
  • easy way to move code to Gemstone
  • but, since GBS is commercial, porting and maintaining should not depend on this
  • use it for porting Values?

1. write code from VW

apapt the code

• class renamings
• namespace treatment
• exclude, add or replace methods

2. read code in Gemstone

apapt the code

• class renamings
• namespace treatment
• exclude, add or replace methods
