graniteds CodeGeneration actionscript3 gas3 generator

shared by kuni katsuya on 01 Aug 12 - No Cached
  • 5.2. Generated ActionScript 3 Classes
  • Gas3 uses the principle of "Base" and customizable inherited classes that let you add methods to generated classes without facing the risk of losing them when a new generation process is executed
  • 5.3. Java Classes and Corresponding Templates
  • ...13 more annotations...
  • summary of templates used by the generator depending on the kind of Java class it encounters:
  • these templates are bundled in the granite-generator.jar archive, in the org.granite.generator.template package and accessible as resources via the class loader
  • class: protocol is used because all standard templates are available in the classpath
  • Alternatively, you may use the file: protocol to load your template from the filesystem. These templates can be specified either by using absolute paths (eg. file:/absolute/path/to/mytemplate.gsp) or paths relative to your current Eclipse project root directory (eg. path/to/mytemplate.gsp).
  • ActionScript 3 generator is able to write AS3 typed client proxies for exposed remote services
  • Compared to the usual Flex RemoteObject, this can greatly help development by bringing
  • auto-completion
  • improved type-safety
  • in Flex when using remote services.
  • replicate validation annotations in order to use the Flex side validation framework
  •  Known Limitations
  • Gas3 does not support inner classes
  • must declare your classes in separated source files if you want them to be correctly handled by the generator

  • Updated Groovy template for GraniteDS Builder (gas3)
  • also stripped out the specialized GraniteDS datatypes in favor of the LCDS serialization convention that Adobe uses (i.e. a Java map should translate to an 'Object' type, a Java enum should translate to a 'String', and Java collections should always serialize as 'ArrayCollection')
  • didn't do a 'base' version and a version that doesnt get touched by the code generator, but you could easily do so by modifying this template

  • It gives people a
  • half-assed solution
  • and somehow shuts down their brains so they
  • stop asking themselves how this solution could be improved upon
  • It's a very impressive magic trick, and I wish I knew how to do it myself. But then, I'm just not like that. I'm always trying to poke holes in things - whether they were Invented Here or Not.
  • but that might be too high-level for your taste. Their are other, less-abstract options.
  • exception handling, this is one area where Spring does a good job: "The Spring Framework's handling of SQLException is one of its most useful features in terms of enabling easier JDBC development and maintenance. The Spring Framework provides JDBC support that abstracts SQLException and provides a DAO-friendly, unchecked exception hierarchy."
  • Utter nonsense and dishonest false advertising
  • Automatic connection closing (and other boiler-plate code) is obviously a hard requirement to be handled by the fwk.
  • Pffffff. It's a trivial requirement which I can solve in my framework with two lines of code in a @Disposes method. Did you see any connection handling in the code above?
  • I mean, seriously guys. The Spring stuff is trivial and not even very elegant. I guess it's easier for me to see that, since I spent half my career thinking about data access and designing data access APIs. But even so...
  • I don't understand. You hate the ability to write typesafw SQL that much?
  • Gavin King
  • Methods with long argument lists are a code smell.
  • It's something Spring copied from Hibernate 1.x, back in the days before varargs
  • It's something we removed in Hibernate2 and JPA.
  • there are a bunch of people
  • who don't want to use JPA.
  • They don't understand, or see the value of, using managed objects to represent their persistent data.
  • Um. Why? Why would that be a bad thing? I imagine that any app with 1000 queries has tens of thousands of classes already. What's the problem? Why is defining a class worse than writing a method?
  • Are you working from some totally bizarre metric where you measure code quality by number of classes?

  • JPA2.0 entities
  • ...31 more annotations...
  • UserService
  • UserDao
  • FacebookWS
  • User u
  • UserService uses UserDAO and FacebookWS
  • but don’t know how those dependencies are instantiated
  • And you shouldn’t really care, all that is important is that UserService depends on dao and webservice object.
  • BDD template given-when-then) tests are easy to read
  • @Entity
  • public class User
  • calling new User(“someName”,”somePassowrd”, “someOtherName”, “someOtherPassword”) becomes hardly readable and maintainable
  • code duplication
  • Maintaining this code would turn into a nightmare in no time
  • running the code above will throw an exception by the JPA provider,
  • since not-nullable password field was never set.
  • Joshua Blooch gives fine example of builder pattern.
  • Instead of making the desired object directly, the client calls a constructor (or static factory) with all of the required parameters and gets a builder object. Then the client calls setter-like methods on the builder object to set each optional parameter of interest. Finally, the client calls a parameterless build method to generate the object, which is immutable. The builder is a static member class of the class it builds.
  • Coffee
  • public static class Builder
  • Builder(CoffeeType type, int cupSize)
  • Builder withMilk()
  • Coffee build()
  • Coffee(this)
  • private Coffee(Builder builder)
  • Coffee coffee = new Coffee.Builder(CoffeeType.Expresso, 3).withMilk().build();2}
  • especially if most of those parameters are optional.
  • For all entity attributes I create private fields
  • those that are obligatory become parameters for the public constructor
  • parameter-less constructor, I create one, but I give him

  • discuss the rationale for migrating your applications from Spring to Java EE 6 and show you real examples of upgrading the web UI, replacing the data access layer, migrating AOP to CDI interceptors, migrating JMX, how to deal with JDBC templates, and as an added bonus will demonstrate how to perform integration tests of you Java EE 6 application using Arquillian
  • EntityManagerClinicTest
  • There is also an interesting Arquillian Persistence extension that integrates DBUnit in Arquillian where you can define your test data externally

  • @RunWith(Arquillian.class)
  • JDBC Templates hardly give any abstraction on top of the database and you’re on your own for Object Relational Mapping. We strongly advise to use JPA wherever possible; it gives portability by abstracting most of the database specific SQL that you would need, and it does all the hard and painful work of object mapping

  • In general, JDBC Templates are a poor solution. They don’t have enough abstraction to work on different databases because you use plain SQL in queries. There is also no real ORM mapping which results in quite a lot of boilerplate code

  • In fact people still love those books without realizing that the world has changed dramatically ever since
  • The reality check here is to wonder whether the rhetorics set forth by Rod Johnson in his 2003/2004 books are still actual today

  • The discussion whether or not to use Spring vs. Java EE for new enterprise Java applications is a no-brainer
  • Why migrate?
  • since then fallen a prey to the hungry minds of Venture Capitalists and finally into the hands of a virtualization company called VMware
  • While the different companies and individuals behind the Spring framework have been doing some work in the JCP their voting behavior on important JSRs is peculiar to say the least
  • outdated ORM solution like JDBC templates
  • some developers completely stopped looking at new developments in the Java EE space and might have lost track of the current state of technology
  • size of the deployment archive
  • fairly standard Java EE 6 application will take up about 100 kilobytes
  • comparable Spring application weighs in at a whopping 30 Megabytes!
  • Lightweight
  • Firing up the latest JBoss AS 7 Application Server from scratch and deploying a full blown Java EE 6 application into the server takes somewhere between two and five seconds on a standard machine. This is in the same league as a Tomcat / Spring combo
  • Dependency injection
  • Java EE 6, the Context and Dependency Injection (CDI) specification was introduced to the Java platform, which has a very powerful contextual DI model adding extensibility of injectable enterprise services
  • Aspect Oriented Programming
  • “AOP Light” and this is exactly what Java EE Interceptors do
  • common pitfall when taking AOP too far is that your code might end up all asymmetric and unreadable. This is due to the fact that the aspect and its implementation are not in the same place. Determining what a piece of code will do at runtime at a glance will be really hard

      generally speaking, there can be a few independent but overlapping mechanism that will control who is allowed to do what with content: 1. any subject's access to the content itself can be controlled via authorization rules (ie. required vs granted permissions) enforced via system-wide resource-based access control 2. content licensors (~content owners) can restrict the usage of their content by: * whom - ie. content licensee (legally/commercially represented by an organization) * how - eg. reuse as unmodified, create derivatives, composite, redistribute, etc * where - ie. distribution channels their content can be used (eg. only on hotel's vbrochure site, but not in any ids/gds channels) * when - temporal restrictions may limit scope of content license grant by: start, end, duration, season, etc 3. content licensees can further filter or funnel content available to them (resulting from a combination of license granted to them and access control) based on their own criteria (eg. generate a templated hotel presentation only if: at least 1 textual description, 5 photos and 1 video for a hotel is available with a license to combine them (composite content)

      this implies that *at least* one version of such (temporarily) replaceable content needs to be managed/maintaned to allow reverting what if, deliberately, ignorantly or maliciously, a user replaces the same piece of--textual or any type, really--content for this hotel n times? will all n versions be required to be managed as an undo history? the user's ''original content'' might have been version 1, but equally might have been 1 mean: - previous version of the content, regardless of which user - initial version of that content attached to the hotel regardless of which user created/updated it and ignoring which organization owns it?, or, -
