addNativeJarLibsJoglCfg

public static final boolean addNativeJarLibsJoglCfg(Class<?>[] classesFromJavaJars)

Loads and adds a JAR file's native library to the TempJarCache, calling addNativeJarLibs(Class[], String) with default JOGL deployment configuration:

        return JNILibLoaderBase.addNativeJarLibs(classesFromJavaJars, "-all");
 

If Class1.class is contained in a JAR file which name includes singleJarMarker -all, implementation will attempt to resolve the native JAR file as follows:

• ClassJar-all.jar to ClassJar-all-natives-os.and.arch.jar

Otherwise the native JAR files will be resolved for each class's JAR file:

• ClassJar1.jar to ClassJar1-natives-os.and.arch.jar
• ClassJar2.jar to ClassJar2-natives-os.and.arch.jar
• ..

addNativeJarLibs

public static boolean addNativeJarLibs(Class<?>[] classesFromJavaJars,
                       String singleJarMarker)

Loads and adds a JAR file's native library to the TempJarCache.
The native library JAR file's URI is derived as follows:

• [1] GLProfile.class ->
• [2] http://lala/gluegen-rt.jar ->
• [3] http://lala/gluegen-rt ->
• [4] http://lala/gluegen-rt-natives-'os.and.arch'.jar

Where:

• [1] is one of classesFromJavaJars
• [2] is it's complete URI
• [3] is it's base URI
• [4] is the derived native JAR filename

Generic description:

       final Class[] classesFromJavaJars = new Class[] { Class1.class, Class2.class };
       JNILibLoaderBase.addNativeJarLibs(classesFromJavaJars, "-all");
 

If Class1.class is contained in a JAR file which name includes singleJarMarker, here -all, implementation will attempt to resolve the native JAR file as follows:

• ClassJar-all.jar to ClassJar-all-natives-os.and.arch.jar

Otherwise the native JAR files will be resolved for each class's JAR file:

• Class1Jar.jar to Class1Jar-natives-os.and.arch.jar
• Class2Jar.jar to Class2Jar-natives-os.and.arch.jar

Examples:

JOCL:

        // only: jocl.jar -> jocl-natives-os.and.arch.jar
        addNativeJarLibs(new Class[] { JOCLJNILibLoader.class }, null, null );
 

JOGL:

       final ClassLoader cl = GLProfile.class.getClassLoader();
       // jogl-all.jar         -> jogl-all-natives-os.and.arch.jar
       // jogl-all-noawt.jar   -> jogl-all-noawt-natives-os.and.arch.jar
       // jogl-all-mobile.jar  -> jogl-all-mobile-natives-os.and.arch.jar
       // jogl-all-android.jar -> jogl-all-android-natives-os.and.arch.jar
       // nativewindow.jar     -> nativewindow-natives-os.and.arch.jar
       // jogl.jar             -> jogl-natives-os.and.arch.jar
       // newt.jar             -> newt-natives-os.and.arch.jar (if available)
       final String newtFactoryClassName = "com.jogamp.newt.NewtFactory";
       final Class[] classesFromJavaJars = new Class[] { NWJNILibLoader.class, GLProfile.class, null };
       if( ReflectionUtil.isClassAvailable(newtFactoryClassName, cl) ) {
           classesFromJavaJars[2] = ReflectionUtil.getClass(newtFactoryClassName, false, cl);
       }
       JNILibLoaderBase.addNativeJarLibs(classesFromJavaJars, "-all");
 

Parameters:

classesFromJavaJars - For each given Class, load the native library JAR.

singleJarMarker - Optional string marker like "-all" to identify the single 'all-in-one' JAR file after which processing of the class array shall stop.

Returns:

true if either the 'all-in-one' native JAR or all native JARs loaded successful or were loaded already, false in case of an error

loadLibrary

protected static boolean loadLibrary(String libname,
                  boolean ignoreError,
                  ClassLoader cl)

Loads the library specified by libname, using the JNILibLoaderBase.LoaderAction set by setLoadingAction(LoaderAction).
The implementation should ignore, if the library has been loaded already.

Parameters:

libname - the library to load

ignoreError - if true, errors during loading the library should be ignored

cl - optional ClassLoader, used to locate the library

Returns:

true if library loaded successful

loadLibrary

protected static void loadLibrary(String libname,
               String[] preload,
               boolean preloadIgnoreError,
               ClassLoader cl)

Loads the library specified by libname, using the JNILibLoaderBase.LoaderAction set by setLoadingAction(LoaderAction).
Optionally preloads the libraries specified by preload.
The implementation should ignore, if any library has been loaded already.

Parameters:

libname - the library to load

preload - the libraries to load before loading the main library if not null

preloadIgnoreError - if true, errors during loading the preload-libraries should be ignored

cl - optional ClassLoader, used to locate the library
