hasXxx() instead of isXxx() [message #424824]

Hi EMF gurus

I'm wondering if it is possible to specify somehow within my model.ecore
or model.genmodel files whether a boolean flag creates a isXxx() or
hasXxx() method.

For example:
I create my model using the ecore/EMF model editor. There I create a
class Person and give it a boolean flag drivingLicense. Now I'd like to
have a Person#hasDrivingLicense() method to be created for the
drivingLicense flag instead of the default Person#isDrivingLicense() flag.

Is that possible and if so, which property do I have to set?

Thanks in advance for any help on this,
Christian

No, just as there is no way to specify get/set/isSet/unset.

You could suppress the "getter" from the generated API using an
EAnnotation as specified by EcoreUtil.setSuppressedVisibility and define
an EOperation with the name you want and with a body annotation that's
just "return isDrivingLicense".
