How the introduction of your project influences functionality |

If you are planning to deprecate/remove/change any existing APIs, |

list them here accompanied with the reason explaining why you |

are doing so. |

<answer id="compat-deprecation"> |
171 |
<p> |
172 |
This module deprecates legacy class |
173 |
<code>org.netbeans.modules.openfile.OpenFileDialogFilter</code> |
174 |
in module |
175 |
<code>utilities</code>. This location for this class is |
176 |
not semantically correct and implementation or friend dependency |
177 |
is required to use it. Making this API public in a more appropriate |
178 |
module has been requested by many users. See bug #209998. |
179 |
</p> |
180 |
<p> |
181 |
The project will influence modules with friend or implementation |
182 |
dependency on module |
183 |
<code>utilities</code> that use legacy abstract class |
184 |
<code>OpenFileDialogFilter</code> in package |
185 |
<code>org.netbeans.modules.openfile</code>. |
186 |
This class is still there, but it is marked as deprecated and will |
187 |
be probably removed soon. |
188 |
</p> |
189 |
<p> |
190 |
The change is known to cause an error if the legacy class is |
191 |
implemented and registered as service with the |
192 |
<code>supersedes</code> annotation. Example: |
193 |
</p> |
194 |
<pre> |
195 |
<code>@ServiceProvider(service = OpenFileDialogFilter.class, |
196 |
position = 100, |
197 |
supersedes = { |
198 |
"org.netbeans.modules.openfile.FileChooser$TxtFileFilter", |
199 |
"org.netbeans.modules.openfile.FileChooser$JavaFilesFilter" |
200 |
}) |
201 |
public class OpenFileFilter extends OpenFileDialogFilter.ExtensionFilter { |
202 |
// ... |
203 |
} </code> |
204 |
</pre> |
205 |
<p> |
206 |
As class |
207 |
<code>org.netbeans.modules.openfile.FileChooser$TxtFileFilter</code> |
208 |
now extends the new SPI class, not the legacy one, it is not allowed |
209 |
to supersede it by any subclass of the legacy interface. |

What other NetBeans projects and modules does this one depend on? |

304 |
Depending on other NetBeans projects influnces the ability of |
305 |
users of your work to customize their own branded version of |
306 |
NetBeans by enabling and disabling some modules. Too |
307 |
much dependencies restrict this kind of customization. If that |

<question id="resources-layer" when="final"> |
1020 |
Does your module provide own layer? Does it create any files or |
1021 |
folders in it? What it is trying to communicate by that and with which |
1022 |
components? |
1023 |
|
1024 |
<hint> |
1025 |
NetBeans allows automatic and declarative installation of resources |
1026 |
by module layers. Module register files into appropriate places |
1027 |
and other components use that information to perform their task |
1028 |
(build menu, toolbar, window layout, list of templates, set of |
1029 |
options, etc.). |

<question id="resources-mask" when="final"> |
1043 |
Does your module mask/hide/override any resources provided by other modules in |
1044 |
their layers? |
1045 |
|
1046 |
<hint> |
1047 |
If you mask a file provided by another module, you probably depend |
1048 |
on that and do not want the other module to (for example) change |
1049 |
the file's name. That module shall thus make that file available as an API |
1050 |
of some stability category. |

<question id="resources-preferences" when="final"> |
1064 |
Does your module uses preferences via Preferences API? Does your module use NbPreferences or |
1065 |
or regular JDK Preferences ? Does it read, write or both? |
1066 |
Does it share preferences with other modules ? If so, then why ? |
1067 |
<hint> |
1068 |
You may use |
1069 |
<api type="export" group="preferences" |
1070 |
name="preference node name" category="private"> |
1071 |
description of individual keys, where it is used, what it |
1072 |
influences, whether the module reads/write it, etc. |
1073 |
</api> |
1074 |
Due to XML ID restrictions, rather than /org/netbeans/modules/foo give the "name" as org.netbeans.modules.foo. |
1075 |
Note that if you use NbPreferences this name will then be the same as the code name base of the module. |

Does your module read any resources from layers? For what purpose? |

As this is some kind of intermodule dependency, it is a kind of API. |

Does your code grant additional rights to some other code? |

permissions to loaded code unless really necessary. |
