Manipulating Oomph setup models programatically [message #1716134]

Hi,

I'd like to manipulate Oomph setup models programmatically and it being an EMF model I'd like to use EMF of course.

I'm able to read a model and traverse it but I'm not able to change property values e.g the VersionRange of a P2Director Requirement element since there is no setters.

Any suggestions?

Regards
Patrik

Patrick,

There's org.eclipse.oomph.p2.Requirement.setVersionRange(VersionRange).

Thanks Ed,

Ok, there is obvioulsy a setVersionRange(), sorry missed that.

Also I wasn't clear on what I'm trying to do which is to change the max version of the range of a requirement.

My assumed approach to this was to get the range, get the max version, increment it and set the new value to the range.

This I can't do since I can't set the Versions in a VersionRange object due to lack of setters.

Then I tried to create a new VersionRange to set. However createVersionRange takes a Version and VersionSegment which I haven't figured out how to use to set specific min and max versions.

Hope this explains my problem better.

Regards
Patrik

Hi Patrik,

P2Factory.createVersionRange(Version, VersionSegment) is a convenience factory method to create version ranges that
include a given version and versions up to the next specified version segment. For example, if you have an installable
unit iu with the version 1.0.0 the call P2Factory.eINSTANCE.createVersionRange(iu.getVersion(), VersionSegment.MICRO)
returns the version range [1.0.0,1.0.1), i.e. all version qualifiers in that range.

Note that VersionRange is really a p2 class. You can create instances directly by calling one of the constructors.

Cheers
