| <!-- Question: arch-what |
| |
| <question id="arch-what"> |
| What is this project good for? |
| <hint> |
| Please provide here few lines describing the the project, |
| what problem it should solve, provide links to documentation, |
| specifications, etc. |
| </hint> |
| </question> |
| --> |

| The module is for parsing JSP pages. The information produced by the parser is then |
| used in other parts of the product. |
| </answer> |
| |
| |
| <!-- Question: compat-i18n |
| |
| <question id="compat-i18n"> |
| Is your module correctly internationalized? |
| <hint> |
| Correct internationalization means that it obeys instuctions |
| at <a href="http://www.netbeans.org/devhome/docs/i18n/index.html"> |
| NetBeans I18N pages</a>. |
| </hint> |
| </question> |

| Yes. |
| </answer> |
| |
| |
| |
| <!-- Question: compat-standards |
| |
| <question id="compat-standards"> |
| Does the module implements or defines any standards? Is the |
| implementation exact or it deviates somehow? |
| </question> |
| --> |
| <answer id="compat-standards"> |
| The parser reads JSP pages which follow the JSP 1.2 standard (including pages |
| written to older versions of the JSP specification). Itself, it does not implement |
| or define a standard. |
| </answer> |
| |
| |
| |
| <!-- Question: compat-version |
| |
| <question id="compat-version"> |
| Does your module properly coexists with earlier and future |
| versions? Can you correctly read settings? Will future |
| versions be able to read settings? |
| |
| <hint> |
| Very helpful for reading settings is to store version number |
| there, so future versions can decide whether how to read/convert |
| the settings and older versions can ignore the new ones. |
| </hint> |
| </question> |
| --> |
| <answer id="compat-version"> |
| The module does not define any persistent information, so it does not need to |
| read old or future settings. |
| </answer> |
| |
| |
| |
| <!-- Question: dep-jre |
| |
| <question id="dep-jre"> |
| Which version of JRE you need (1.2, 1.3, 1.4, etc.)? |
| <hint> |
| It is expected that if your module runs on 1.x that it will run |
| on 1.x+1 if no, state that please. Also describe here cases where |
| you run different code on different versions of JRE and why. |
| </hint> |
| </question> |
| --> |
| <answer id="dep-jre"> |
| It uses JRE 1.3. |
| </answer> |
| |
| |
| |
| <!-- Question: dep-jrejdk |
| |
| <question id="dep-jrejdk"> |
| Do you require JDK or is JRE enough? |
| </question> |
| --> |
| <answer id="dep-jrejdk"> |
| The module requires the JDK. The reason is the fact that the Tomcat server, |
| whose component is used as a third party library, needs the JDK. |
| </answer> |

| |
| <question id="dep-non-nb"> |
| What other non-NetBeans projects this one depends on? |
| |
| <hint> |
| Some non-NetBeans projects are packaged as NetBeans modules |
| (see <a href="http://libs.netbeans.org">libraries</a>) and |
| it is prefered to use this approach when more modules may |
| depend on such third-party library. |
| </hint> |
| </question> |

| |
| <!-- Question: deploy-packages |
| |
| <question id="deploy-packages"> |
| 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/apis/org/openide/doc-files/upgrade.html#3.4-public-packages"> |
| public packages |
| </a>). |

| <!-- Question: exec-classloader |
| |
| <question id="exec-classloader"> |
| Does your code uses own classloader? |
| <hint> |
| A bit unusual. Please explain why and what for. |
| </hint> |
| </question> |
| --> |
| <answer id="exec-classloader"> |
| Yes. It uses a classloader class imported from the <code>web-core</code> friend API. This classloader |
| is used by the Tomcat JSP compiler/parser libraries (it is passed as a parameter). The reason is that |
| the JSP compiler needs to load user classes present in the Web Application the user is developing, so the |
| custom classloader simulates what the app will look like at runtime. |
| </answer> |
| |
| |
| |
| <!-- Question: exec-component |
| |
| <question id="exec-component"> |
| Is execution of your code influenced by (string) property |
| of any of your components? |
| |
| <hint> |
| Often <code>JComponent.getClientProperty</code>, <code>Action.getValue</code> |
| or <code>PropertyDescriptor.getValue</code>, etc. are used to influence |
| a behaviour of some code. This of course forms an interface that should |
| be documented. Also if one depends on some interface that an object |
| implements (<code>component instanceof Runnable</code>) that forms an |
| API as well. |
| </hint> |
| </question> |
| --> |
| <answer id="exec-component"> |
| No. |
| </answer> |
| |
| |
| |
| <!-- Question: exec-privateaccess |
| |
| <question id="exec-privateaccess"> |
| Are you aware of any other part of the system calling some of |
| your methods by reflection? |
| <hint> |
| If so, describe the "contract" as an API. Likely private or friend one, but |
| still API and consider rewrite of it. |
| </hint> |
| </question> |
| --> |

| <!-- Question: exec-property |
| |
| <question id="exec-property"> |
| Is execution of your code influenced by any environment of |
| system (<code>System.getProperty</code>) property? |
| |
| <hint> |
| If there is a property that can change the behaviour of your |
| code, somebody will likely use it. You should describe what it does |
| and the stability category of this API. You may use |
| <PRE> |
| <property name="id" category="private" > |
| description of the property, where it is used, what it influence, etc. |
| </property> |
| </PRE> |
| </hint> |

| I think not. |
| </answer> |
| |
| |
| |
| <!-- Question: exec-reflection |
| |
| <question id="exec-reflection"> |
| Does your code uses java.lang.reflect to execute some other code? |
| <hint> |
| This usually indicates a missing or unsufficient API in the other |
| part of the system. If the other side is not aware of your dependency |
| this contract can be easily broken. |
| </hint> |
| </question> |
| --> |
| <answer id="exec-reflection"> |
| Yes. It uses reflection to access private fields and methods in the Tomcat JSP compiler/parser library. |
| </answer> |

| </answer> |
| |
| |
| |
| <!-- Question: format-types |
| |
| <question id="format-types"> |
| Which file formats your code reads or writes on disk? |
| </question> |
| --> |
| <answer id="format-types"> |
| It reads files which make up the user's web application, e.g. JSPs, tag libraries, |
| the deployment descriptor etc. These are described by the JSP and Servlet specifications. |
| </answer> |
| |
| |
| |
| <!-- Question: lookup-lookup |

| <hint> |
| Do you register using layer file or using <code>META-INF/services</code>? |
| Who is supposed to find your component? |
| </hint> |
| </question> |
| --> |
| <answer id="lookup-register"> |
| The module registers the implementation of the <code>JSPParserAPI</code> class defined by the |
| <code>web-core</code> friend API, through an XML layer file. |
| </answer> |
| |
| |
| |
| <!-- Question: lookup-remove |
| |
| <question id="lookup-remove"> |
| Do you remove entries of other modules from lookup? |

| <question id="perf-limit"> |
| Are there any limits in number/size of elements your code |
| can handle? |
| </question> |
| --> |
| <answer id="perf-limit"> |
| The horse power of the machine is a limiting factor, as parsing JSP pages |
| can be demanding resource-wise. |
| </answer> |
| |
| |
| |
| <!-- Question: perf-mem |
| |
| <question id="perf-mem"> |
| What is the amount of memory your component occupies? Estimate |
| with a relaction to the number of windows, etc. |
| </question> |
| --> |
| <answer id="perf-mem"> |
| Relatively to the number of windows, it's pretty high (as there are no windows) :-) |
| It occupies a reasonable amount of memory necessary to do the parsing job. |
| It also keeps a cache of parsed tag libraries constructed from the user application. |
| </answer> |
| |
| |
| |
| <!-- Question: perf-menus |
| |
| <question id="perf-menus"> |
| Does your module use dynamically changing context menus or |

| |
| <question id="perf-progress"> |
| Does your module executes some long running task? |
| <hint>Typically they are tasks like connecting over |
| network, computing huge amount of data, compilation. |
| Such communication should be done asynchronously (for example |
| using <code>RequestProcessor</code>), definitively it should |
| not block AWT thread. |
| </hint> |
| </question> |
| --> |
| <answer id="perf-progress"> |
| Yes. I guess parsing can be considered long. |
| </answer> |
| |
| |
| |
| <!-- Question: perf-scale |
| |
| <question id="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? |
| Please include some estimates. |
| </question> |
| --> |

| |
| <!-- Question: resources-file |
| |
| <question id="resources-file"> |
| Does your module use <code>java.io.File</code> directly? |
| |
| <hint> |
| NetBeans provide a logical wrapper over plain files called |
| <code>org.openide.filesystems.FileObject</code> that |
| provides uniform access to such resources and is the prefered |
| way that should be used. But of course there can be situations when |
| this is not suitable. |
| </hint> |
| </question> |
| --> |
| <answer id="resources-file"> |
| Yes. The Tomcat JSP Compiler library expects <code>java.io.File</code> to be passed to it. |
| </answer> |
| |
| |
| |
| <!-- Question: resources-layer |
| |
| <question id="resources-layer"> |
| Does your module provide own layer? Does it create some files or |
| folders on it? What it is trying to communicate by that and with which |
| component? |
| |
| <hint> |
| NetBeans allows automatic and declarative installation of resources |
| by module layers. Module register files into appropriate places |
| and other components use that information to perform their task |
| (build menu, toolbar, window layout, list of templates, set of |
| options, etc.). |
| </hint> |
| </question> |
| --> |
| <answer id="resources-layer"> |
| Yes. It registers an implementation of an interface class declared by the <code>web-core</code> API |
| with the <code>web-core</code> module. |
| </answer> |
| |
| |
| |
| <!-- Question: resources-mask |
| |
| <question id="resources-mask"> |
| Does your module mask/hide/override any resource provided by another one in |
| module layer? |
| |
| <hint> |
| If you mask a file provided by another module, you probably depend |
| on that and do not want the other module to (for example) change |
| the file's name. That module shall thus make that file available as an API |
| of some stability category. |
| </hint> |
| </question> |
| --> |
| <answer id="resources-mask"> |
| No. |
| </answer> |
| |
| |
| |
| <!-- Question: resources-read |
| |
| <question id="resources-read"> |
| Does your module read any resources from layers? For what purpose? |
| |
| <hint> |
| As this is some kind of intermodule dependency, it is a kind of API. |
| Please describe it and clasify according to |
| <a href="http://openide.netbeans.org/tutorial/api-design.html#categories"> |
| common stability categories</a>. |
| </hint> |
| </question> |
