## Class PsConfig

- java.lang.Object
- - jv.object.PsConfig

-     public final class PsConfig
      extends java.lang.Object

  Static configuration class of JavaView with global static variables. The class must be initialized with current applet and frame. Initialization is automatically done in `PvViewer` when PvViewer instance is created in the top applet. If applet does not create an instance of PvViewer then applet must initialize this class directly using its `init` method.

  Information about version, authors etc. is parsed during generation of jar file to be included as manifest information (currently, the information is just added as a file `_jarVersion.txt` to the archive).

  - ### Constructor Detail

    - #### PsConfig

          public PsConfig()

  - ### Method Detail

    - #### isApplication

          public static boolean isApplication()

      Returns `true` if run as application, else `false`. E.g. applet.stub is not initialized when applet does not run in browser. This information is used e.g. in PsDebug when displaying status messages.

      JavaView runs as application if and only if the argument `frame != null` in `PsConfig.init(Applet,Frame)`. Therefore it is essential to call `PsConfig.init`. Usually, this initialization is automatically done in the constructor of PvViewer, but it can be done by hand, if no PvViewer is created.

      See Also:
        `init(Applet, PsViewerIf, Frame)`, `PvViewer.PvViewer(Applet, Frame)`

    - #### setApplication

          public static void setApplication(boolean flag)

      Determines status of this program if running as applet or application.
      See Also:
        `isApplication()`

    - #### getApplet

          public static java.applet.Applet getApplet()

      Get applet if run as applet.

    - #### getFrame

          public static java.awt.Frame getFrame()

      Get frame to be used as parent frame for dialogs. If a frame has been specified as argument of `PsConfig.init(Applet,Frame)` this frame is return. Otherwise an invisible new frame is generated upon the first invocation.

    - #### getViewer

          public static PsViewerIf getViewer()

      Get viewer. Viewer manages the 3d-displays, control window, and list of projects. It is the central class in JavaView, and usually created at the beginning of an applet or application. This instance variable gives access to PvViewer, e.g. to show/hide dialogs and panels.
      See Also:
        `PsViewerIf`, `PvViewerIf`, `PvViewer.PvViewer(Applet, Frame)`

    - #### runGC

          public static void runGC()

      Finalize and run system gc until not further gain up to a total of 40 gc loops.
      Since:
        JavaView v2.22.001

    - #### runGC

          public static void runGC(int intensity,
                   int loops)

      Finalize and run system gc until not further gain up to a total of 40 gc loops.
      Since:
        JavaView v2.22.001

    - #### reset

          public static void reset()

      Clear all registered instances of applet, frame and viewer. Method should be invoked when applets are being destroyed in order to speed up the garbage collection.

      Calling init() after a reset() will lead to a full new initialization of this class. If no reset() is invoked, subsequent init() calls will be ignored after the first init() call.

      Since:
        JavaView v2.22.001
      See Also:
        `init(Applet, Frame)`

    - #### init

          public static void init(java.applet.Applet applet,
                  PsViewerIf viewer,
                  java.awt.Frame frame)

      Initialize this configuration class.
      See Also:
        `PvViewer.PvViewer(Applet, Frame)`, `init(Applet, Frame)`, `reset()`

    - #### init

          public static void init(java.applet.Applet applet,
                  java.awt.Frame frame)

      Initialize this configuration class. Method must be called once and only once when JavaView is launched.

      If argument `frame == null` and `applet != null` then program runs as applet, and applet is used to access codebase etc. Otherwise, the program runs as application.

      Initialization must be done as soon as possible in an applet or application since system properties are parsed and evaluated. Usually, method is called automatically in the constructor of PvViewer.

      See Also:
        `reset()`

    - #### getVersion

          public static int[] getVersion(int id)

      Get the version number of a JavaView resource.
      Returns:
        array with three integers with major, minor and built number.
      See Also:
        `getVersion()`

    - #### getLocale

          public static java.util.Locale getLocale()

      Get the current language locale, for example, for number formatting. Default locale is English. Locale is determined by the current language setting.
      Returns:
        current locale
      See Also:
        `setLanguage(String)`

    - #### getPanelVersion

          public static int getPanelVersion()

      Get unique id which characterizes version of current language and font setting. Id determines if panels need to be recreated. Previously, the language was used as sole criterium, but now changing global font settings will also increment the central panel version.
      Returns:
        Unique id describes version of panel fonts and languages.

    - #### getLanguage

          public static java.lang.String getLanguage()

      Get the current language used in localizations.
      Returns:
        two letter id of language in {"de", "en", ...}

    - #### setLanguage

          public static void setLanguage(java.lang.String language)

      Set the current language used in localizations. Any subsequent call of `getMessage(String)` will return a message in the selected language.

      This method does not change any existing labels or menu items which must be done by hand at other place.

      Parameters:
        `language` - Two letter id of language in {"de", "en", ...}

    - #### hasArchive

          public static boolean hasArchive(int archiveID)

      Test whether this applet or application has access to a certain JavaView archive. This test tries to find a class by name within the given archive. The class-for-name test is performed only once during the first search for that archive.
      Since:
        JavaView 2.38

    - #### getMessage

          public static java.lang.String getMessage(int key)

      Get localized translation of message. Never set an interface label or menu entry directly with a string but always call this method to obtain the localized version of the current locale.

      Usage of this method reduces the Java archives since the message string is no longer multiply stored.

      Parameters:
        `key` - message identifier whose localized text is requested
      Returns:
        message message in localized form for use as label etc
      See Also:
        `getMessage(String)`

    - #### getMessage

          public static java.lang.String getMessage(boolean bNew,
                                    int groupId,
                                    java.lang.String keyval)

      Temporary method to get localized translation of message. This method will soon be replaced by getMessage(int).
      Parameters:
        `bNew` - if true then return keyval, else return getMessage(keyval)
        `groupId` - five digit integer representing a message group
        `keyval` - either value or key of a message
      Returns:

      If using the default language or if the current resource bundle failed to deliver the requested message, then use message from the default language. The messages of the default language are store in `PsResource`.

      Parameters:
        `key` - message identifier whose localized text is requested
      Returns:
        message message in localized form for use as label etc

    - #### getProject

          public static java.lang.String getProject()

      Get name of project as string.

    - #### getOSName

          public static java.lang.String getOSName()

      Get name of operating system as string. Might not be available because of security restrictions.
      Returns:
        name of operating system, or `null` if not identified.
      See Also:
        `getOSId()`

    - #### getOSId

          public static int getOSId()

      Get index of current operating system. Index determines the behaviour of JavaView such as font names and sizes. If operating system could not be identified, for example, because of security restrictions, then `OS_WIN` is used as default. Use method `getOSName()` to check whether system could be identified.
      Returns:
        name of operating system, or `OS_WIN` if not identified.
      See Also:
        `getOSName()`

    - #### getProperties

          public static java.util.Hashtable getProperties()

      Get JavaView and system properties. Call 'System.getProperties()' led to a security exception. Replace by single direct calls 'System.getProperty(String)'

    - #### parseArgs

          public static void parseArgs(java.lang.String[] args,
                       java.util.Properties props)

      Store given command-line arguments as system properties by adding to each parameter to the system properties list. In general, an parameter must have the form

          property=value

      Note, parameters containing blanks should be enclosed in quotes.

      There are two exceptions:

      1. JavaView model files.
      JavaView model files may either be specified using the above property=value scheme or simply as a single or list of files. For example, filenames specified in a model parameter are

          model=myFile.jvx

      or

          model=myFile1.jvx;myFile2.obj

      and, alternatively, filenames may appear as blank separated list of filenames such as

          myFile.jvx

      or

          myFile1.jvx myFile2.obj

      In the later case the property "model" is automatically generated and multiply geometry files are concatenated with ";"-separators in a single "model" property.

      2. JavaView display files:
      A single display file may be passed to JavaView similar like model files either as a property

          displayFile=myFile.jvd

      or simply as a filename (which is detected by its filename extension JVD)

          myFile.jvd

    - #### getParameter

          public static java.lang.String getParameter(java.lang.String name)

      Return a parameter from the system properties list. Each JavaView parameter has been added to the system property hashtable. Name of parameter is not case-sensitive.
      Parameters:
        `name` - Name of parameter whose value is requested, not case-sensitive.
      Returns:
        value Value of parameter

    - #### getUserBase

          public static java.lang.String getUserBase()

      Get user directory of current application from where JavaView was launched.
      Since:
        JavaView 3.09.003
      See Also:
        `getCodeBase()`

    - #### setUserBase

          public static void setUserBase(java.lang.String userBase)

      Since:
        JavaView 3.09.003
      See Also:
        `getCodeBase()`

    - #### getCodeBase

          public static java.lang.String getCodeBase()

      Get codebase of current applet or application.

      This method just returns the codebase as string. The codebase was most likely automatically determined in `init(Applet,Frame)`, or it was assigned using `setCodeBase(String)`.

      If JavaView runs as application then the codeBase ends with current file separator.

      See Also:
        `init(Applet,Frame)`, `getFileSeparator()`

    - #### setCodeBase

          public static void setCodeBase(java.lang.String aCodeBase)

      Set codebase of current applet or application. Usually the codebase is automatically determined by JavaView.

      If JavaView runs as application then the codeBase ends with current file separator.

      If JavaView is running locally within a web page then some browser use the the "file:" protocol to access local files. In this case, some browsers, notably IE, modify the codebase and replace blanks with %20. This leads to a FileNotFoundException when later reading a local file. I solved this problem by replacing any %20 in a codebase argument of this method if the codebase starts with "file:".

      Parameters:
        `aCodeBase` - new codebase
      See Also:
        `getFileSeparator()`

    - #### getInstBase

          public static java.lang.String getInstBase()

      Get instbase of current applet or application.

      This method just returns the instbase as string. The instbase was most likely automatically determined in `init(Applet,Frame)`, or it was assigned using `setCodeBase(String)`.

      If JavaView runs as application then the codeBase ends with current file separator.

      See Also:
        `getCodeBase()`

    - #### setInstBase

          public static void setInstBase(java.lang.String aInstBase)

      Set instbase of current application, for example, as command line parameter.

      If JavaView runs as application then the instbase ends with current file separator.

      See Also:
        `getCodeBase()`

    - #### getFileSeparator

          public static char getFileSeparator()

      Always return "/", and do not use system file separator. Previously. the file separator of system properties was used, but since Java gives the separator of the client instead of the server this behaviour led to problems. Since on windows systems "/" seems to work we use it as default.

    - #### getFont

          public static java.awt.Font getFont(int type)

      Get font for specific textual application type, like FONT_TEXT, FONT_HEADER2 etc. Selected font size and name depends on current operating system.

    - #### setFont

          public static boolean setFont(int os,
                        int type,
                        java.lang.String name,
                        int style,
                        int size)

      Set font for specific textual application type, like FONT_TEXT, FONT_HEADER2 etc. Only those gui widgets are affected which are constructed AFTER this call, so this method should probably be called right after JavaView starts. Note, that in general only a rather small set of fonts and font characteristics are supported. Especially, fonts supported on one OS may not be supported on other systems.

      Use JavaView applet `SystemFonts` to show a list all available fonts.

      Parameters:
        `os` - identifier of operating system among OS_WIN etc. If os==-1 use current osId.
        `type` - identifier among FONT_TEXT, FONT_HEADER2 etc.
        `name` - name of font such as SansSerif, Monospaced etc. If name==null leave current name.
        `style` - use among Font.PLAIN, Font.BOLD etc. If style==-1 leave current style.
        `size` - any size which is supported by Java and operating system. If size==-1 leave current size.

    - #### isDev

          public static final boolean isDev()

      Temporary method, avoid usage.
