< question id = " deploy - jar " when = " impl " >
Do you deploy just module JAR file ( s ) or other files as well ?
< hint >
Usually a module consist of one JAR file ( perhaps with Class - Path
extensions ) and also a configuration file that enables it . If you
have any other files , use
& lt ; api group = " java . io . File " name = " yourname " type = " export " category = " friend " &an>gt ; . . . & lt ; / api & gt ;
to define the location , name and stability of your files ( of course
changing " yourname " and " friend " to suit your needs ) .
If it uses more than one JAR , describe where they are located , how
they refer to each other .
If it consist of module JAR ( s ) and other files , please describe
what is their purpose , why other files are necessary . Please
make sure that installation / uninstallation leaves the system

<!--
< question id = " deploy - packages " when = " init " >
Are packages of your module made inaccessible by not declaring them
public ?
< hint >
NetBeans module system allows restriction of access rights to
public classes of your module from other modules . This prevents
unwanted dependencies of others on your code and should be used
whenever possible ( < a href = " http : / / www . netbeans . org / download / javadoc / OpenAPIs / org / openide / doc - files / upgrade . html # 3 . 4 - public - packages " >
public packages
< / a > ) . If you do not restrict access to your classes you are
making it too easy for other people to misuse your implementation
details , that is why you should have good reason for not
restricting package access .

< question id = " exec - ant - tasks " when = " impl " >
Do you define or register any ant tasks that other can use ?
< hint >
If you provide an ant task that users can use , you need to be very
careful about its syntax and behaviour , as it most likely forms an
API for end users and as there is a lot of end users , their reaction
when such API gets broken can be pretty strong .

< hint >
Often < code > JComponent . getClientProperty < / code > , < code > Action . getValue < / code >
or < code > PropertyDescriptor . getValue < / code > , etc . are used to influence
a behavior of some code . This of course forms an interface that should

Check for cases when you have an object of type A and you also
expect it to ( possibly ) be of type B and do some special action . That

Is execution of your code influenced by any environment or
Java system ( < code > System . getProperty < / code > ) property ?
< hint >
If there is a property that can change the behavior of your
code , somebody will likely use it . You should describe what it does
and the < a href = " http : / / openide . netbeans . org / tutorial / api - design . html # life " > stability category < / a >

<answer id ="exec-property" >
<p>
<api type ="export" group="systemproperty" name="netbeans.user" category="devel" >
During runtime the JNLP launcher enhances the behaviour of the <code>netbeans.user</code>
property as defined in the NetBeans core. In addition to standard
content provided from core,
it can contain string <q>${user.home}/</q> which gets replaced
with the correct location of user directory.
</api>
</p>
<p>
<api type ="export" group="systemproperty" name="netbeans.jnlp.fixPolicy" category="devel" >
During runtime the JNLP launcher checks whether value <code>true</code> is assigned
to this system property. If it is "true" a special security policy is applied
for all the code base - it is granting all permissions to all code bases.
<strong>Use with care!</strong>. It allows you e.g. to have the module
jar files unsigned (they must also not require the all-permissions in
their .jnlp file for this to to work).
</api>
</p>
</answer>
<!--
< question id = " exec - reflection " when = " impl " >
Does your code use Java Reflection to execute other code ?

This usually indicates a missing or insufficient API in the other

this contract can be easily broken .

< question id = " exec - threading " when = " impl " >
What threading models , if any , does your module adhere to ?
< hint >
If your module calls foreign APIs which have a specific threading model ,
indicate how you comply with the requirements for multithreaded access
( synchronization , mutexes , etc . ) applicable to those APIs .
If your module defines any APIs , or has complex internal structures
that might be used from multiple threads , declare how you protect
data against concurrent access , race conditions , deadlocks , etc . ,
and whether such rules are enforced by runtime warnings , errors , assertions , etc .
Examples : a class might be non - thread - safe ( like Java Collections ) ; might
be fully thread - safe ( internal locking ) ; might require access through a mutex
( and may or may not automatically acquire that mutex on behalf of a client method ) ;
might be able to run only in the event queue ; etc .
Also describe when any events are fired : synchronously , asynchronously , etc .

Which protocols and file formats ( if any ) does your module read or write on disk ,

Files can be read and written by other programs , modules and users . If they influence
your behaviour , make sure you either document the format or claim that it is a private
api ( using the & lt ; api & gt ; tag ) .

If you generate an ant build file , this is very likely going to be seen by end users and

Does your module use dynamically updated context menus , or

If you do a lot of tricks when adding actions to regular or context menus , you can significantly
slow down display of the menu , even when the user is not using your action . Pay attention to
actions you add to the main menu bar , and to context menus of foreign nodes or components . If
the action is conditionally enabled , or changes its display dynamically , you need to check the
impact on performance . In some cases it may be more appropriate to make a simple action that is
always enabled but does more detailed checks in a dialog if it is actually run .
