java javadoc BestPractices documentation design communication

shared by kuni katsuya on 13 Dec 12 - No Cached
  • Javadoc coding standards
  • explain some of the rationale for some of my choices
  • this is more about the formatting of Javadoc, than the content of Javadoc
  • ...63 more annotations...
  • Each of the guidelines below consists of a short description of the rule and an explanation
  • Write Javadoc to be read as source code
  • Making Javadoc readable as source code
  • Public and protected
  • All public and protected methods should be fully defined with Javadoc
  • Package and private methods do not have to be, but may
  • benefit from it.
    • kuni katsuya
      kuni katsuya on 13 Dec 12
       
      think of it as internal design documentation when you revisit this code 8 months from now: - based on nothing but your well-chosen ;) package/class/method/variable names, will you recall all of your current design intentions and rationale? likely not - when you hand-off this code to another software engineer, how easy will it be to mostly rtfm? will you have to waste time preparing design/implementation notes specifically for the hand-off? if this is the case because the code is unreadable and not self-guiding and there's not already at least high level design notes in a wiki, you're doing it wrong!
  • If a method is overridden in a subclass, Javadoc should only be present if it says something distinct to the original definition of the method
    • kuni katsuya
      kuni katsuya on 13 Dec 12
       
      ie. don't just copy-paste the javadoc from the superclass. that's mindless and pointless monkey work
  • Use the standard style for the Javadoc comment
  • Do not use '**/' at the end of the Javadoc
  • Use simple HTML tags, not valid XHTML
  • XHTML adds many extra tags that make the Javadoc harder to read as source code
  • Use a single <p> tag between paragraphs
  • Place a single <p> tag on the blank line between paragraphs:
    • kuni katsuya
      kuni katsuya on 13 Dec 12
       
      this at least makes the paragraph breaks wysiwygísh and somewhat easier to read
  • Use a single <li> tag for items in a list
  • place a single <li> tag at the start of the line and no closing tag
  • Define a punchy first sentence
  • it has the responsibility of summing up the method or class to readers scanning the class or package
  • the first sentence should be
  • clear and punchy, and generally short
  • use the third person form at the start
  • Avoid the second person form, such as "Get the foo"
  • Use "this" to refer to an instance of the class
  • When referring to an instance of the class being documented, use "this" to reference it.
  • Aim for short single line sentences
  • Wherever possible, make Javadoc sentences fit on a single line
  • favouring between 80 and 120 characters
  • Use @link and @code wisely
  • @link feature creates a visible hyperlink in generated Javadoc to the target
  • @code feature provides a section of fixed-width font, ideal for references to methods and class names
  • Only use @link on the first reference to a specific class or method
  • Use @code for subsequent references.
  • This avoids excessive hyperlinks cluttering up the Javadoc
  • Never use @link in the first sentence
  • Always use @code in the first sentence if necessary
  • Adding a hyperlink in that first sentence makes the higher level documentation more confusing
  • Do not use @code for null, true or false
  • Adding @code for every occurrence is a burden to both the reader and writer of the Javadoc and adds no real value.
  • Use @param, @return and @throws
  • @param entries should be specified in the same order as the parameters
  • @return should be after the @param entries
  • followed by @throws.
  • Use @param for generics
  • correct approach is an @param tag with the parameter name of <T> where T is the type parameter name.
  • Use one blank line before @param
  • This aids readability in source code.
  • Treat @param and @return as a phrase
  • They should start with a lower case letter, typically using the word "the". They should not end with a dot. This aids readability in source code and when generated.
  • treated as phrases rather than complete sentences
  • Treat @throws as an if clause
  • phrase describing the condition
  • Define null-handling for all parameters and return types
    • kuni katsuya
      kuni katsuya on 13 Dec 12
       
      ideally, if the method in question has any specified/required pre and/or post conditions, they should be noted in the javadoc, not *just* null handling also, there are cleaner ways to design around this type of old school null handling hackage
  • methods should define their null-tolerance in the @param or @return
  • standard forms expressing this
  • "not null"
  • "may be null"
  • "null treated as xxx"
    • kuni katsuya
      kuni katsuya on 13 Dec 12
       
      DO NOT DO THIS this is just bad design
  • "null returns xxx"
    • kuni katsuya
      kuni katsuya on 13 Dec 12
       
      this might also stink of poor design ymmv
  • In general the behaviour of the passed in null should be defined
  • Specifications require implementation notes
  • Avoid @author
  • source control system is in a much better position to record authors
  • This wastes everyone's time and decreases the overall value of the documentation. When you have nothing useful to say, say nothing!
    • kuni katsuya
      kuni katsuya on 13 Dec 12
       
      likewise with javadoc on things like default constructors /**  * Creates an instance of SomeClass  */ public SomeClass() {} is equally useless and unnecessarily clutters up the source code

shared by kuni katsuya on 25 Jul 12 - No Cached
  • queries are also known as native queries
  • SQL Queries
  • reasons why a developer using JP QL might want to integrate SQL queries into their application
  • ...32 more annotations...
  • JPA 2.0, still contains only a subset of the features supported by many database vendors
  • features not supported in JP QL.
  • performance required by an application is to replace the JP QL query with a hand-optimized SQL version. This may be a simple restructuring of the query that the persistence provider was generating, or it may be a vendor-specific version that leverages query hints and features specific to a particular database.
  • recommend avoiding SQL initially if possible and then introducing it only when necessary
  • benefits of SQL query support is that it uses the same Query interface used for JP QL queries. With some small exceptions that will be described later, all the Query interface operations discussed in previous chapters apply equally to both JP QL and SQL queries.
  • keep application code consistent because it needs to concern itself only with the EntityManager and Query interfaces.
  • An unfortunate result of adding the TypedQuery interface in JPA 2.0 is that the createNativeQuery() method was already defined in JPA 1.0 to accept a SQL string and a result class and return an untyped Query interface
  • consequence is that when the createNativeQuery() method is called with a result class argument one might mistakenly think it will produce a TypedQuery, like createQuery() and createNamedQuery() do when a result class is passed in.
  • @NamedNativeQuery
  • resultClass=Employee.class
  • The fact that the named query was defined using SQL instead of JP QL is not important to the caller
  • SQL Result Set Mapping
  • JPA provides SQL result set mappings to handle these scenarios
  • A SQL result set mapping is defined using the @SqlResultSetMapping annotation. It may be placed on an entity class and consists of a name (unique within the persistence unit) and one or more entity and column mappings.
  • entities=@EntityResult(entityClass=Employee.class)
  • @SqlResultSetMapping
  • Multiple Result Mappings
  • A query may return more than one entity at a time
  • The SQL result set mapping to return both the Employee and Address entities out of this query
  • emp_id, name, salary, manager_id, dept_id
  • address_id, id, street, city, state, zip
  • order in which the entities are listed is not important
  • ntities={@EntityResult(entityClass=Employee.class), @EntityResult(entityClass=Address.class)}
  • expected result type and therefore received an instance of TypedQuery that is bound to the expected type. By qualifying the result type in this way, the getResultList() and getSingleResult() methods return the correct types without the need for casting.
  • Defining a Class for Use in a Constructor Expression
  • public EmpMenu(String employeeName, String departmentName)
  • List<EmpMenu>
  • NEW example.EmpMenu(" + "e.name, e.department.name)
  • EmpMenu.class
  • createNamedQuery() can return a TypedQuery whereas the createNativeQuery() method returns an untyped Query
  • List<Employee>
  • createNamedQuery("orgStructureReportingTo", Employee.class)

Java security SpringSecurity

shared by kuni katsuya on 09 Aug 12 - Cached
  • Domain object instance security: In many applications it's desirable to define Access Control Lists (ACLs) for individual domain object instances. We provide a comprehensive ACL package with features including integer bit masking, permission inheritance (including blocking), an optimized JDBC-backed ACL repository, caching and a pluggable, interface-driven design.
  • OpenID Support: the web's emerging single sign-on standard (supported by Google, IBM, Sun, Yahoo and others) is also supported in Spring Security
  • Easy integration with existing databases: Our implementations have been designed to make it easy to use your existing authentication schema and data (without modification). Of course, you can also provide your own Data Access Object if you wish. Password encoding: Of course, passwords in your authentication repository need not be in plain text. We support both SHA and MD5 encoding, and also pluggable "salt" providers to maximise password security.
  • ...5 more annotations...
  • Caching: Spring Security optionally integrates with Spring's Ehcache factory. This flexibility means your database (or other authentication repository) is not repeatedly queried for authentication information when using Spring Security with stateless applications.
  • Run-as replacement: The system fully supports temporarily replacing the authenticated principal for the duration of the web request or bean invocation. This enables you to build public-facing object tiers with different security configurations than your backend objects.
  • Tag library support: Your JSP files can use our taglib to ensure that protected content like links and messages are only displayed to users holding the appropriate granted authorities. The taglib also fully integrates with Spring Security's ACL services, and obtaining extra information about the logged-in principal.
  • User Provisioning APIs: Support for groups, hierarchical roles and a user management API, which all combine to reduce development time and significantly improve system administration.
  • Enterprise-wide single sign on using CAS 3: Spring Security integrates with JA-SIG's open source Central Authentication Service (CAS)

shared by kuni katsuya on 08 Aug 12 - No Cached
  • previously known as the JSecurity project
  • The word Subject is a security term that basically means "the currently executing user"
  • Core Concepts: Subject, SecurityManager, and Realms
  • ...12 more annotations...
  • Subject
  • 'Subject' can mean a human being, but also a 3rd party process, daemon account, or anything similar. It simply means 'the thing that is currently interacting with the software'
  • Subject currentUser = SecurityUtils.getSubject();
  • SecurityManager
  • SecurityManager manages security operations for all users
  • Realms
  • Realm acts as the ‘bridge’ or ‘connector’ between Shiro and your application’s security data. That is, when it comes time to actually interact with security-related data like user accounts to perform authentication (login) and authorization (access control), Shiro looks up many of these things from one or more Realms configured for an application.
  • Realm is essentially a security-specific DAO
  • Shiro provides out-of-the-box Realms to connect to a number of security data sources (aka directories) such as LDAP, relational databases (JDBC), text configuration sources like INI and properties files, and more
  • Authorization
  • A permission is a raw statement of functionality, for example ‘open a door’, ‘create a blog entry’, ‘delete the ‘jsmith’ user’, etc. By having permissions reflect your application’s raw functionality, you only need to change permission checks when you change your application’s functionality. In turn, you can assign permissions to roles or to users as necessary at runtime.

  • the constraint implementation is in the same class as the constraint declaration (not a problem in a dynamic language) @Pattern has a sightly different semantic because the regexp engine in Flex is a bit different. instead of the features provided by ConstraintValidatorContext, you can define a properties attribute in your constraints to make it belong to several sub-properties. not as flexible but good enough in many cases.

  • Project permissions can be granted to:
  • Individual usersGroupsProject rolesIssue roles such as 'Reporter', 'Project Lead' and 'Current Assignee''Anyone' (e.g. to allow anonymous access)A (multi-)user picker custom field.A (multi-)group picker custom field. This can either be an actual group picker custom field, or a (multi-)select-list whose values are group names.
  • Many other permissions are dependent on this permission

      example of dependencies *between* permissions. eg, in this case, work-on-issues permission 'needs' browse-projects permission could be expressed as a permission hierarchy where if work-on-issues permission is granted, means/implies that user already has browse-projects permission (w-o-i perm 'subsumes' b-p perm) might imply permission hierarchy

  • Permission Schemes
  • A permission scheme is a set of
  • user/group/role
  • assignments for the project permissions
  • Every project has a permission scheme
  • One permission scheme can be associated with multiple projects
  • Permission schemes prevent having to set up permissions individually for every project
  • it can be applied to all projects that have the same type of access requirements

  • Dependency injection discourages object-oriented programming?
  • if you’re using DI, and you have an X entity, do you have an XService or XManager with lots of method where X is the first argument?

      evidence of the anti-pattern of procedural design in a java ee6 cdi application
  • previous way is more procedural

      well, dependency injection, but moreover, the soa approach to service design tends to force otherwise intelligent software engineers into doing procedural design the services just end up being bags of method calls that implement any type of behavior, with the domain objects or entity beans being reduced to mere data structures with little responsibility or behavior beyond persistence. (which, in this anti-pattern, is typically mostly provided by the repository or dao class! ie. domain object crud)
  • it’s just easier

      ... if you just blindly follow the anti-pattern, of course  ;)
  • many benefits

      with the procedural approach, you also cannot implement polymorphic behavior, for instance
  • builder
  • fluent interface
  • it’s not for small projects
    • kuni katsuya
      kuni katsuya on 12 Dec 12
       
      fuckwhat? small or big matters not. if di is applied poorly, regardless of project size, it's an anti-pattern! disregard these comments!
  • problems with DI frameworks:

  • Classical synchronous model: 10,000 concurrent users -> 11,000 server threads. 1.1 ratio.
  • Comet asynchronous model: 10,000 concurrent users -> 250 server threads. 0.025 ratio.
  • classical (synchronous) servlet model
  • request -> immediate processing -> response
  • Comet implementations rely on a different model:
  • request -> wait for available data -> response

Shiro Realm

shared by kuni katsuya on 09 Aug 12 - No Cached
  • A Realm is a component that can access application-specific security data such as users, roles, and permissions. The Realm translates this application-specific data into a format that Shiro understands so Shiro can in turn provide a single easy-to-understand Subject programming API no matter how many data sources exist or how application-specific your data might be.
  • A Realm is essentially a security-specific DAO
