RE: [wtp-dev] Virtual API progress
|
Some comments on the comments ... most
of all, thanks for providing these notes so we can all stay in the loop.
Am I reading this right ... "module"
is becoming "component" .... guess everyone's discussed alternatives
and could think of anything better, but 'component' is already heavily
used in Eclipse, and we would then even be in the position of having a
component named 'component'! ... I'm sure we'll get years of fun explaining
that to people. :)
And also, my opinion on
the use of 'common' component. I think of that as the component for
things that do not really have to do with webtools per se. I do not believe
its for "commonly used UI things and emf utilities" ... for a
few reasons. One, "commonly used" by itself isn't enough to make
it a WTP API, it has to be good too. Neither should it be used to solve
pre-req problems (in the past, there's a trend to move things further and
further down to solve pre-req problems, so everyone wanted their favorite
things in 'common' but in reality, this just make for more unrelated dependancies)
So ... if it is commonly used, and good enough to be API in WTP, why isn't
it an API in base UI packages, or EMF packages? Are there road blocks
in moving things to their rightful home? If so, perhaps Architecture Group
could help resolve?
(Feel free to bring issues to us if
we can help resolve questions/issues).
[I don't feel strong where 'module'
ends up . but just wanted to dispel the notion of putting little utilities
in common.]
Thanks

Some suggestions (based on various offline discussions):
1) Purge "module" from the plugin. I know
it will require a bunch of repackaging and documentation update, but it's
pretty confusing to transition from ModuleCore to the "Component"
type heirarchy.
2) Remove "common" from the package name? I
don't feel strongly about this one, but while you're doing the big refactor,
maybe the root package should be "org.eclipse.wst.component"?
I understand using "common" to qualify shared ui widgets
or emf utilities, but it doesn't seem necessary for navigator and component.
3) Create IComponent and IComponentType interfaces.
Move methods in ModuleCore like getComponentType(IVirtualContainer)
into IComponent. IComponent would probably be a subtype of IVirtualContainer.
4) Move the EMF impl classes to an "emf"
subpackage. The following organization seems reasonable to me:
org.eclipse.wst.component
IComponent
IComponentType
IVirtualContainer, etc.
org.eclipse.wst.component.emf
WorkbenchComponent
ComponentType
VirtualContainer
A client can restrict itself to the top-level
interfaces if it doesn't want or need to take an EMF dependency, but the
EMF classes are available if you are developing an editing feature.
5) Add a path type object. For example,
instead of ModuleCore/IComponent.getSourceContainers(), the api would be
something like IComponent.getVirtualContainers(IPathType)
Potential path types: Java Source,
Java Resource, Web Resource, EAR Resource, etc.
I'm not sure how includes/excludes filtering
is intended to be handled. Something modeled after the way the JDT
does it, I would assume...

Subject: [wtp-dev] Virtual API progress
Extended Team:
We have been making progress on the
proposal to expose a "Virtual
Path API" to allow clients to browse flexible project structures without
dealing directly with the underlying EMF models. We are beginning to lean
towards making the models wholly internal to allow us the freedom to make
changes in the next release of WTP if necessary. Are there any opinions
out
there about this?
The initial cut of the API is already
available in CVS under the
modelcore plugin
(wst/components/org.eclipse.wst.common.modulecore/modulecore-src/org.eclipse.wst.common.modulecore.internal.resources).
We are targeting this weeks Integration Build to have the API tests in
places and most if not all of the javadoc. The one thing that hasn't yet
been addressed is how we intend to expose the Referenced Components
(formerly Dependent Workbench Modules) through the Virtual Path API. We
started by coping the IResource, IContainer, IFolder, and IFile, and then
pruning those down to methods that deal with navigation. The javadoc is
not
yet ready, so any docs that are there are left over from Eclipse Platform.
We also added methods that were more specific that we thought would be
helpful: getWorkspaceRelativePath(), getProjectRelativePath() [as in
Platform], getRuntimePath(), getRealFile(s)/Folder(s)(), and
getComponentName().
We are also considering changing our
use of the EMF URI object to use
the more Eclipse-friendly IPath object to model path structures within
the
model. By making the models internal, we allow ourselves the opportunity
to
make this change at a later time (e.g. R1.1), but are considering making
this change as quickly as this Friday. Any thoughts?
