Permission (Apache Shiro 1.2.1 API) - 0 views

  • A Permission represents the ability to perform an action or access a resource. A Permission is the most granular, or atomic, unit in a system's security policy and is the cornerstone upon which fine-grained security models are built.
  • a Permission instance only represents functionality or access - it does not grant it
  • permissions are immutable and reflect an application's raw functionality
  • ...4 more annotations...
  • because Permissions represent raw functionality and only change when the application's source code changes, they are immutable at runtime - they represent 'what' the system can do
  • by transitive association, the user 'has' the permissions in their roles
  • all Permission checks are relegated to Realm implementations, and only those implementations really determine how a user 'has' a permission or not
  • Realm could use the semantics described here, or it could utilize some other mechanism entirely

8. Bean Validation (JSR-303) - Confluence - 0 views

  • "Bean Validation" specification (aka JSR-303) standardizes an annotation-based validation framework for Java
  • Flex doesn't provide by itself such framework. The standard way of processing validation is to use Validator subclasses and to bind each validator to each user input (see Validating data). This method is at least time consuming for the developer, source of inconsistancies between the client-side and the server-side validation processes, and source of redundancies in your MXML code.
  • GraniteDS introduces an ActionsScript3 implementation of the Bean Validation specification and provides code generation tools integration so that your Java constraint annotations are reproduced in your AS3 beans
  • ...16 more annotations...
  • GraniteDS validation framework provides a set of standard constraints
  • Constraint Description AssertFalse The annotated element must be false AssertTrue The annotated element must be true DecimalMax The annotated element must be a number whose value must be lower or equal to the specified maximum DecimalMin The annotated element must be a number whose value must be greater or equal to the specified minimum Digits The annotated element must be a number whithin accepted range Future The annotated element must be a date in the future Max The annotated element must be a number whose value must be lower or equal to the specified maximum Min The annotated element must be a number whose value must be greater or equal to the specified minimum NotNull The annotated element must not be null Null The annotated element must be null Past The annotated element must be a date in the past Pattern The annotated String must match the supplied regular expression Size The annotated element size must be between the specified boundaries (included)
  • Constraint annotations must be placed on public properties, either public variables or public accessors
  • -keep-as3-metadata+=AssertFalse,AssertTrue,DecimalMax,DecimalMin, Digits,Future,Max,Min,NotNull,Null,Past,Pattern,Size
  • must use
  • keep the constraint annotations in your compiled code
  • Error Messages and Localization
  • {name.notnull}
  • {name.minsize}
  • use the built-in ResourceBundle support offered by Flex:
  • to add support for different locales
  • follow the same principle:
  • create a ValidationMessages.properties for the new locale
  • translate all default error messages and add new ones for your customized message keys
  • Note that the bundle name must always be set to "ValidationMessages".
  • Using the FormValidator Class

java - Flex+JPA/Hibernate+BlazeDS+MySQL how to debug this monster? - Stack Overflow - 0 views

  • Set break points in my Java code Start up the Java application server with the appropriate debug JVM properties set (e.g. -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n) From Eclipse, I attach a remote debugger to the app server on the default port 8000. The Java Debugger will open up when a break point is hit. Set breakpoints in my Flex application (or one of its modules). From Eclipse (with Flash Builder) I launch a debug configuration for my Flex app. The Flex Debugger will open up when a break point is hit. At this point I have two debuggers open and everything work great. Two other things I do: a) extend the transaction system timeout, so it doesn't get trigger while I am sitting there think for a few minutes b) use Charles Proxy (in reverse proxy mode) inbetween the client and server to watch the AMF traffic and view payloads, etc.

java - what is difference between EntityManager.find() and EntityManger.getReference()?... - 0 views

  • what is difference between EntityManager.find() and EntityManger.getReference()?
  • find()
  • return an initialized instance of your object
  • ...6 more annotations...
  • If it is not already loaded in the EntityManager, it is retrieved from the database
  • getReference()
  • is allowed to return a proxy instread of an initialized instance, if the entity has not been loaded in the EntityManager before
  • In this proxy,
  • only the primary key attribute is initialized
  • Proxies can be created without hitting the database

Preemptive commit comments | Arialdo Martini - 0 views

  • Tell me what the software does
    • kuni katsuya
       
      tell me how the software should *behave*, not how the behavior was *implemented* ie. describe the changes in this commit from the behavioral perspective rather than implementation details
  • What is the project behavior, in this snapshot?
  • What did the programmers, in order to produce this snapshot?
  • ...43 more annotations...
  • committing comments describing the
  • behavior of the software,
  • rather than the
  • implementation or a description of what we did
  • commits’ comments started to look like BDD’s methods name: a description of a behavior.
  • principles
  • Talk about the feature, not about yourself
  • Don’t refer to the past
  • I know it’s now
  • list of benefits
  • More focus while developing
  • Commit review is much easier
  • Less cognitive load
  • You learn commenting much more precisely
  • commit comment becomes a
  • declaration of intent
  • like a BDD method name
  • No more “Just a fix“, “Improvements” or “I made this, this, this and also this” comments.
    • kuni katsuya
       
      BDD/TDD or any methodology aside, these are the worst commit comments as they are as useless as empty commit comments
  • Each preemptive comment triggers a micro design session
  • A preemptive comment sets a micro goal
    • kuni katsuya
       
      which also aligns well with the 'micro goal' or incremental deliverables approaches of most agile methodologies 
  • helps to focus a goal to be reached
  • Without preemptive comments, I often went on coding, always asking myself: “Should I commit now? Have I reached a stable state which I could consider a good commit?“
  • define micro-goals through preemptive comments
  • macro-goal through the feature branch name
  • A preemptive comment creates a little timebox
    • kuni katsuya
       
      similar to the timeboxing strategy of a short sprints, for instance
  • Writing comments preemptively puts the agreement between the pair members to a test
    • kuni katsuya
       
      more relevant to methodologies using pair programming
  • commit history gains a very balanced granularity
  • feature branch becomes a collection of evolutionary commits each of which has usually a 1:1 binding with tests
  • very easy to find which commit introduced a bug, since each commit is related to a single new goal/feature
  • Preemptive commit comments
  • Rule #2: write what the software
  • I started taking a lot of care of the words I was using in comments, commits, test names and classes/variables/methods’ names
  • be supposed to do,
  • not what you did
  • should
  • Introducing BDD
  • began with the simple attempt to replace the world
  • “should“
  • “test”
  • with the world
  • Rule #1: write commit comments before coding
  • use the same criteria for my commits’ comments as well.
  • (not what you did)

  • command-line syntax and programming APIs remain entirely upward compatible with ImageMagick 5.5.2

  • ImageMagick does not offer any of these things
  • more time has been spent optimizing and debugging its code
  • dramatically fewer dependencies on external libraries
  • much smaller than ImageMagick
  • installation footprint is 3-5X smaller than ImageMagick
  • usually faster than ImageMagick
  • more efficient at dealing with large images
  • GraphicsMagick has been significantly updated to use multiple CPU cores to speed up the image processing
  • non-parallelizable code paths often dominating the time
