General Information

Question (arch-what): What is this project good for?
Answer:

Provides support infrastructure for projects working with the Java language.

Question (arch-overall): Describe the overall architecture.
Answer:
• JavaProjectAPI -

  The Java Project API is actually entirely SPI and supplies useful implementations of Java-related functionality specific to the project system.

• ProjectClassPathExtender -

  Implemented by java/j2seproject and asked for by form. Permits the Form Editor to add JavaBeans archives to the classpath of a J2SE project automatically.

  ProjectClassPathSupport -

  Support class containg helper method for creating ClassPathImplementation based on Ant properties.

Question (arch-usecases): Describe the main use cases of the new API. Who will use it under what circumstances? What kind of code would typically need to be written to use the module?
Answer:

Project type providers wishing to show Java packages in their logical views can use this SPI. Templates which are Java-centric can use it. Projects which wish to implement queries from the Java Support APIs can place implementations in their lookup and these will be delegated to automatically.

Question (arch-time): What are the time estimates of the work?
Answer:

Complete.

Question (arch-quality): How will the quality of your code be tested and how are future regressions going to be prevented?
Answer:

Non-GUI portions (including node-based UI) ought to be covered by unit tests. GUI portions may be covered by IDE-wide functional tests.

Question (arch-where): Where one can find sources for your module?

   OpenIDE-Module-Module-Dependencies: org.netbeans.modules.java.project/1 > 1.8.22
  

Compatibility with environment

Answer:

Yes.

Question (compat-standards): Does the module implement or define any standards? Is the implementation exact or does it deviate somehow?
Answer:

No.

Answer:

No settings.

Access to resources

Question (resources-file): Does your module use java.io.File directly?
Answer:

In a few places as circumstances require.

Question (resources-layer): Does your module provide own layer? Does it create any files or folders in it? What it is trying to communicate by that and with which components?
Answer:

Registers iterators for Java templates. Also registers context menu actions for Java source files. Registers a couple of options, and adds an action to the Projects tab to switch package display style.

Question (resources-read): Does your module read any resources from layers? For what purpose?
Answer:

No.

Question (resources-mask): Does your module mask/hide/override any resources provided by other modules in their layers?
Answer:

Registers iterators for Java templates.

Lookup of components

Question (lookup-lookup): Does your module use org.openide.util.Lookup or any similar technology to find any components to communicate with? Which ones?
Answer:

Delegating query implementations search project lookups for their delegates. PackageViewChildren.PackageNode.setName() looks for one instance of org.netbeans.spi.java.project.support.ui.PackageRenameHandler.

Question (lookup-register): Do you register anything into lookup for other code to find?
Answer:

Delegating query implementations are registered to global lookup. The AntLogger used for stack trace hyperlinking is registered.

Question (lookup-remove): Do you remove entries of other modules from lookup?
Answer:

No.

Execution Environment

Question (exec-property): Is execution of your code influenced by any environment or Java system (System.getProperty) property?
Answer:
• org.netbeans.spi.java.project.support.ui.packageView.TRUNCATE_PACKAGE_NAMES -

  If set to true, displays a truncated version of Java package names, usually in the Projects tab.

• org.netbeans.spi.java.project.support.ui.packageView.USE_TREE_VIEW -

  If set to true, displays Java packages in a tree rather than a flat list, usually in the Projects tab.

Answer:

None.

Question (format-dnd): Which protocols (if any) does your code understand during Drag & Drop?
Answer:

None.

No.

Question (perf-scale): Which external criteria influence the performance of your program (size of file in editor, number of files in menu, in source directory, etc.) and how well your code scales?
Answer:

Number of subpackages for the package view (since they are all displayed in a list).

Question (perf-limit): Are there any hard-coded or practical limits in the number or size of elements your code can handle?
Answer:

None known.

Question (perf-mem): How much memory does your component consume? Estimate with a relation to the number of windows, etc.

Question (perf-wakeup): Does any piece of your code wake up periodically and do something even when the system is otherwise idle (no user interaction)?
Answer:

No.

Question (perf-progress): Does your module execute any long-running tasks?
Answer:

Answer:

No, only template wizard panels.

Question (perf-menus): Does your module use dynamically updated context menus, or context-sensitive actions with complicated and slow enablement logic?
