General Information

Question (arch-what): What is this project good for?
Answer: The Input/Output API is a small API module which contains InputOutput and related interfaces used in driving the Output Window. The normal implementation is org.netbeans.core.output2.
Question (arch-overall): Describe the overall architecture.
Answer: InputOutputAPI -

Just an API/SPI for defining the output window.

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:

There is an SPI but additional implementations are not expected. The API is most important.

Simple usage example:

InputOutput io = IOProvider.getDefault().getIO("My Window", true);
io.select();
OutputWriter w = io.getOut();
w.println("Line of plain text.");
OutputListener listener = new OutputListener() {
    public void outputLineAction(OutputEvent ev) {
        StatusDisplayer.getDefault().setStatusText("Hyperlink clicked!");
    }
    public void outputLineSelected(OutputEvent ev) {
        // Let's not do anything special.
    }
    public void outputLineCleared(OutputEvent ev) {
        // Leave it blank, no state to remove.
    }
};
w.println("Line of hyperlinked text.", listener, true);

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

Done.

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

Too little code to test.

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

Project and platform dependencies

Question (dep-nb): What other NetBeans projects and modules does this one depend on?
Answer:
• UtilitiesAPI

The default answer to this question is:


These modules are required in project.xml:

• UtilitiesAPI - The module is needed for compilation. The module is used during runtime. Specification version 6.2 is required.
Question (dep-non-nb): What other projects outside NetBeans does this one depend on?
Answer: None
Question (dep-platform): On which platforms does your module run? Does it run in the same way on each?
Answer: Any
Question (dep-jre): Which version of JRE do you need (1.2, 1.3, 1.4, etc.)?
Answer: 1.4
Question (dep-jrejdk): Do you require the JDK or is the JRE enough?
Answer: JRE

Deployment

Question (deploy-jar): Do you deploy just module JAR file(s) or other files as well?
Answer: Just the module JAR.
Question (deploy-nbm): Can you deploy an NBM via the Update Center?
Answer: Yes
Question (deploy-shared): Do you need to be installed in the shared location only, or in the user directory only, or can your module be installed anywhere?
Answer: Anywhere
Question (deploy-packages): Are packages of your module made inaccessible by not declaring them public?
Answer: No; only API classes are public.
Question (deploy-dependencies): What do other modules need to do to declare a dependency on this one, in addition to or instead of the normal module dependency declaration (e.g. tokens to require)?
Answer:

You will very likely also want to declare

OpenIDE-Module-Requires: org.openide.windows.IOProvider

to ensure that an Output Window implementation is in fact enabled.

Compatibility with environment

Question (compat-i18n): Is your module correctly internationalized?
Answer: Yes.
Question (compat-standards): Does the module implement or define any standards? Is the implementation exact or does it deviate somehow?
Answer: The module defines an API.
Question (compat-version): Can your module coexist with earlier and future versions of itself? Can you correctly read all old settings? Will future versions be able to read your current settings? Can you read or politely ignore settings stored by a future version?
Answer: N/A
Question (compat-deprecation): How the introduction of your project influences functionality provided by previous version of the product?
WARNING: Question with id="compat-deprecation" has not been answered!

Access to resources

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

No, but the implementation may.

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: No.
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: No
Question (resources-preferences): Does your module uses preferences via Preferences API? Does your module use NbPreferences or or regular JDK Preferences ? Does it read, write or both ? Does it share preferences with other modules ? If so, then why ?
WARNING: Question with id="resources-preferences" has not been answered!

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: IOProvider.getDefault() asks lookup for the first instance of itself. This is normally provided by org.netbeans.core.output2.
Question (lookup-register): Do you register anything into lookup for other code to find?
Answer: No
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? On a similar note, is there something interesting that you pass to java.util.logging.Logger? Or do you observe what others log?
Answer: No
Question (exec-component): Is execution of your code influenced by any (string) property of any of your components?
Answer: No

Answer:

No.

Question (exec-classloader): Does your code create its own class loader(s)?

Answer: N/A
Question (format-clipboard): Which data flavors (if any) does your code read from or insert to the clipboard (by access to clipboard on means calling methods on java.awt.datatransfer.Transferable?

Answer: No
Question (perf-exit): Does your module run any code on exit?
Answer: 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?
