|Re: [Wtp-wst-dev] XPath 2.0 User Doc Plugin|
We'll just have to make sure we update the New Help for Old Friends V page if we go breaking the API and document the reasons why.
Also, please make sure that you have your PDE API Tooling Target Platform setup so that we can catch any minor api breakage, and where we have to add a compatibility setting. I've taken care of the ones for the latest check in.
Latest code has been tagged as well and released to the build, with your changes and my fn:resolve-uri implementation, we are down to 290 failures.

I would usually totally agree with your comments about API stability, but are you sure anybody except Mukul are actually using PsychoPath at this point? And are we under obligation to be API stable between milestones?-Jesper On 02/09/2009, at 16.39, David Carver wrote:I agree that the API needs refactoring.Some of these classes are currently in an API layer, so if we go this route, we need to make sure that their is an API compatibility layer.Where the classes/interfaces are internal, we have a bit more freedom on the refactoring.The method names with the underscores are legacy, and came with the initial code contribution. That type of refactoring especially in classes that are in API packages now, will require a bump of the major version since we are breaking the API contract.I might suggest for the DefaultDynamicContext, marking it Deprecated, and then creating a new Interface with your suggested refactorings. Please also remember to update the User Interface wiki page with any proposed redesign.http://wiki.eclipse.org/PsychoPathXPathProcessor/UserInterface As well as the Design Document: http://wiki.eclipse.org/PsychoPathXPathProcessor/DesignFor now, the biggest pressing issues is to make sure that we get to 100% compliance on the test suite. These refactorings and re-designs can be done after that work is completed.Dave Jesper Steen Møller wrote:Nice done, tying the Wiki part to the distributed docs.However, it reminds me that I would really like to change some parts of API. The overall changes I'll propose are these:A) ResultSequenceA1) Turn ResultSequence into an interface, and make it immutable, i.e. no more clear(), add(), and concat(). A2) Provide simple implementations for the the empty sequence, singleton sequences, and fixed length sequences. A3) Introduce a class ResultBuilder which has the methods required for building a ResultSequence. A4) Introduce a ResultSequence.modify() which returns a ResultBuilder and provide copy-on-use semantics, w.r.t. the underlying List.B) DefaultDynamicContextWe are mixing the elements of the dynamic and static contexts - I can't see how that's good for the adopters. Example when using XPath for Schema 1.1: - On loading the grammar, a static context is produced, one for each XPath expression (since e.g. namespace prefixes are going to be different). It may make sende for Xerces to provide their own StaticContext, so the shared parts like function libraries are shared, but e.g. the namespaces can differ. Then, for each assertion in a parse/validation run, a dynamic context is in use, and has to "adhere to" the static context of that expression.The proposed changes are then:- Change DefaultDynamicContext to delegate to the DefaultStaticContext instead of extending it. Or just provide a "getStaticContext" getter instead.C) Functions coupled to the static and even the dynamic contexts. This prevents sharing of function libraries. Rather, we should pass the dynamic context in when evaluating (especiallly if we add the getStaticContext to the DynamicContext interface?)D) Cosmetic: why are the function names not camelCase, but underscoreRidden ? shouldn't we at least mimic the style of the DOM standards, e.g. http://www.w3.org/TR/DOM-Level-3-XPath/java-binding.html which is obviously for XPath 1.0, but still worth looking at?Comments, anyone? Unless someone objects, I'll open a bug for each of A-D and submit suggested patches and explanations.-JesperOn Wed, Sep 2, 2009 at 3:07 AM, David Carver <d_a_carver@xxxxxxxxx <mailto:d_a_carver@xxxxxxxxx>> wrote:With the complete of bug 286070 , the PsychoPath user documentationand SDK documentation plugins have been created.
