| knowing the get/set method names of an attribute [message #645335] |

Hi
say that I have an attribute in a class, say foo, the generated get and
set names are
getFoo/setFoo
however, I guess I cannot simply assume that the pattern is
"get" + s.substring(0, 1).toUpperCase() + s.substring(1);
if s is the attribute name, since in cases where the corresponding
get/set method name clashes with a same name of the java library the
generated code takes care about that
for instance, if the attribute is "class" the get method will not be
getClass()
which would clash with the java library getClass(), but
getClass_()
so I was wondering what is the algorithm for getting the get method
name, if I have an attribute? Is it accessible via some util method?
thanks in advance
Lorenzo

Not in general, no.

Exactly.

All such things are handled by the GenModel. Looking at the templates
you can pretty much figure it out. Things like getGetAccessor do the
work...
If you want to generate code that properly maps onto what EMF is
generating, you really should be reusing the GenModel...

What are you trying to solve? Do you want to call this using reflection?
- in this case you use eGet/eSet.

mhh... using reflection I'd lose static type checking, wouldn't I?
My goal is to generate Java code from a DSL where I access attributes of
EMF classes and objects...
thanks

Lorenzo,
For generation purposes, you should use the GenModel. It provides
hundreds of conveniences and essentials...
Cheers,
Ed

OK, I will!
But is GenModel documented? Or is there any doc online or kind of
tutorial or example?
thanks in advance

Lorenzo,
How it works is self evident from the names. :-P
Your best bet is generally to look at how it's used in EMF's various
templates. I.e., if you need to generate code that calls the generated
getter, look at what's used to generate the name of the getter in
Class.javajet.
