Hi Thomas,
Given that an IRequirement no longer must contain name, namespace, and
range, but instead can be an arbitrary _expression_ applied on an
IInstallableUnit, perhaps we can help you find an alternative solution.
Can you say something about why you need access to the requirement
internals?
Regards,
Thomas Hallgren

Only the following things will make it
in
the API:
org.eclipse.equinox.internal.p2.metadata.
IRequiredCapability
org.eclipse.equinox.internal.provisional.p2.
director.IDirector
org.eclipse.equinox.internal.provisional.p2.
director.IPlanner
org.eclipse.equinox.internal.provisional.p2.
director.PlanExecutionHelper
org.eclipse.equinox.internal.provisional.p2.
director.ProfileChangeRequest
org.eclipse.equinox.internal.provisional.p2.
metadata.MetadataFactory
What's up with that? Can you please
provide detailed instructions on implementing an equivalent to
isOptional()
using getMin() and getMax()? The javadoc present in the IRequirement
class is just too overwhelming (I'm being sarcastic :-).
Also, if it's really true that
IRequiredCapability
will not be API in 3.6, can you also provide instructions on
implementing
equivalents to getName(), getNamespace(), and getRange() using
IRequirement
API.
This got replaced by the getMin getMax on IRequirement.
You will also notice that IRequiredCapability is no
longer
API.

In "eclipse-SDK-I20100217-1031-win32.zip", the isOptional() method

Where did this go? What should be used instead?
Good point. The work on MetadataFactory needs to be done.

Re: [p2-dev] IRequiredCapability internal? |
I understand that there are potentially many forms of IRequirement.
That
makes sense, but that does not mean that the API provided by
IRequiredCapability
is not still useful to clients. They just need to be aware that this
isn't
the only kind of IRequirement. For example, we create requirements via
MetadataFactory.createRequiredCapability(). How do we create concrete
requirements
without an API?
IRequiredCapability was limiting in what it could express. For example
it could not express negation and or'ing, and it could only described
dependencies
on something that had a namespace, a name and a version and we are
striving
to express requirements and capabilities on other things (for example
BundleExecutionEnvironment).
As such, to ensure for API evolution we have turned the too specific
IRequiredCapability
into an IRequirement.
IProvidedCapability is still API, but it is very likely that it will
either
be turned into something more generic, or be marked internal if we
don't
have the time to make it API.
As for IRequirementChange the reference to IRequiredCapability is
something
that we have still left to do (https://bugs.eclipse.org/bugs/show_bug.cgi?id=299506)
The situation of the API now is that we have tried to move all the
types
that we needed to see made API in a final package for M5, however we
still
have work to do to reach the final state for 3.6 (hopefully by M6).
If you have feedback, it is very much appreciated,
HTH

[p2-dev] IRequiredCapability internal? |
I'm migrating from Eclipse 3.5 to Eclipse 3.6 (I20100119-0800). Can
someone
explain why IRequiredCapability is now internal in 3.6 when it was
provisional
API in 3.5? What is the rationale for making this internal? Why is
IProvidedCapability
considered API when IRequiredCapability is not? Why does the
IRequirementChange
API have a matches() method whose parameter type is IRequiredCapability
an internal API? _______________________________________________
