5 // Requires JSmolCore.js and (for now; probably) JSmol.js
\r
6 // This version of j2slib requires jQuery and works in both Chrome and MSIE locally,
\r
7 // though Chrome cannot read local data files, and MSIE cannot read local binary data files.
\r
9 // Java programming notes by Bob Hanson:
\r
11 // There are a few motifs to avoid when optimizing Java code to work smoothly
\r
12 // with the J2S compiler:
\r
16 // 1. an array with null elements cannot be typed and must be avoided.
\r
17 // 2. instances of Java "instance of" involving arrays must be found and convered to calls to Clazz.isA...
\r
18 // 3. new int[n][] must not be used. Use instead JU.AU.newInt2(n);
\r
19 // 4. new int[] { 1, 2, 3 } has problems because it creates simply [ ] and not IntArray32
\r
23 // 1. Remember that EVERY number in JavaScript is a double -- doesn't matter if it is in IntArray32 or not.
\r
24 // 2. You cannot reliably use Java long, because doubles consume bits for the exponent which cannot be tested.
\r
25 // 3. Bit 31 of an integer is unreliable, since (int) -1 is now , not just 0zFFFFFFFF, and
\r
26 // FFFFFFFF + 1 = 100000000, not 0. In JavaScript, 0xFFFFFFFF is 4294967295, not -1.
\r
27 // This means that writeInt(b) will fail if b is negative. What you need is instead
\r
28 // writeInt((int)(b & 0xFFFFFFFFl) so that JavaScript knocks off the high bits explicitly.
\r
32 // 1. j2sRequireImport xxxx is needed if xxxx is a method used in a static function
\r
33 // 2. URL.getContent() is not supported. Use other means based on URL.toString()
\r
34 // 3. It is critical for performance to avoid any significant amount of function overloading.
\r
35 // In particular, methods such as xxx(int a, int b) and xxx(float a, int b) MUST be renamed,
\r
36 // because JavaScript only has Number, and there is absolutely no way to tell these apart.
\r
37 // It's probably bad Java programming, anyway.
\r
38 // 4. Calls to super(...) can almost always be avoided. These trigger the SAEM
\r
39 // (searchAndExecuteMethod) call, and it is very destructive to performance.
\r
40 // Just find another way to do it.
\r
42 // NOTES by Bob Hanson:
\r
44 // J2S class changes:
\r
46 // BH 7/24/2015 6:48:50 AM adding optional ?j2sdebug flag on page URL
\r
47 // -- switches to using j2s/core/corexxx.js, not j2s/core/corexxx.z.js
\r
48 // -- adds ";//# sourceURL="+file in eval(js)
\r
49 // -- enables DebugJS.$(msg) call to debugger;
\r
50 // see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/debugger
\r
51 // see https://developer.mozilla.org/en-US/docs/Tools/Debugger/How_to/Debug_eval_sources

52 // BH 7/23/2015 6:45:55 PM added sourceURL in each js class eval(), allowing full
\r
53 // breakpoint debugging and code checking in Firefox and Chrome
\r
54 // BH 7/19/2015 6:18:17 PM added os.name, line.separator, etc. to System.getProperty()

\r
57 // BH 7/18/2015 6:08:05 PM for Jmol I was able to remove the $private/$fx business, but now
\r
58 // I see that in general that cannot be done. Thinking about a strategy...
\r
59 // BH 7/18/2015 4:43:38 PM better handling of TypeError and InternalError for e.getMessage() and e.getStackTrace()
\r

\r
72 // BH 4/12/2015 11:48:03 AM added Clazz.getStackTrace(-n) -- reports actual parameter values for n levels
\r

\r
3273 * ClassLoader Summary
\r
3275 * ClassLoader creates SCRIPT elements and setup class path and onload
\r
3276 * callback to continue class loading.
\r
3278 * In the onload callbacks, _Loader will try to calculate the next-to-be-
\r
3279 * load *.js and load it. In *.js, it will contains some codes like
\r
3280 * Clazz.load (..., "$wt.widgets.Control", ...);
\r
3281 * to provide information to build up the class dependency tree.
\r
3283 * Some known problems of different browsers:
\r
3284 * 1. In IE, loading *.js through SCRIPT will first triggers onreadstatechange
\r
3285 * event, and then executes inner *.js source.
\r
3286 * 2. In Firefox, loading *.js will first executes *.js source and then
\r
3287 * triggers onload event.
\r
3288 * 3. In Opera, similar to IE, but trigger onload event. (TODO: More details
\r
3289 * should be studied. Currently, Opera supports no multiple-thread-loading)
\r
3291 * For class dependency tree, actually, it is not a tree. It is a reference
\r
3292 * net with nodes have n parents and n children. There is a root, which
\r
3293 * ClassLoader knows where to start searching and loading classes, for such
\r
3294 * a net. Each node is a class. Each class may require a set of must-classes,
\r
3295 * which must be loaded before itself getting initialized, and also need a set
\r
3296 * of optional classes, which also be loaded before being called.
\r
3298 * The class loading status will be in 6 stages.
\r
3299 * 1. Unknown, the class is newly introduced by other class.
\r
3300 * 2. Known, the class is already mentioned by other class.
\r
3301 * 3. Loaded, *.js source is in memory, but may not be initialized yet. It
\r
3302 * requires all its must-classes be intiailized, which is in the next stage.
\r
3303 * 4. Musts loaded, all must classes is already loaded and declared.
\r
3304 * 5. Delcared, the class is already declared (_Loader#isClassDefined).
\r
3305 * 6. Optionals loaded, all optional classes is loaded and declared.
\r
3307 * The ClassLoader tries to load all necessary classes in order, and intialize
\r
3308 * them in order. For such job, it will traverse the dependency tree, and try
\r
3309 * to next class to-be-loaded. Sometime, the class dependencies may be in one
\r
3310 * or more cycles, which must be broken down so classes is loaded in correct
\r
3313 * Loading order and intializing order is very important for the ClassLoader.
\r
3314 * The following technical options are considered:
\r
3315 * 1. SCRIPT is loading asynchronously, which means controling order must use
\r
3316 * callback methods to continue.
\r
3317 * 2. Multiple loading threads are later introduced, which requires the
\r
3318 * ClassLoader should use variables to record the class status.
\r
3319 * 3. Different browsers have different loading orders, which means extra tests
\r
3320 * should be tested to make sure loading order won't be broken.
\r
3321 * 4. Java2Script simulator itself have some loading orders that must be
\r
3322 * honored, which means it should be integrated seamlessly to Clazz system.
\r
3323 * 5. Packed *.z.js is introduced to avoid lots of small *.js which requires
\r
3324 * lots of HTTP connections, which means that packed *.z.js should be treated
\r
3325 * specially (There will be mappings for such packed classes).
\r
3326 * 6. *.js or *.css loading may fail according to network status, which means
\r
3327 * another loading try should be performed, so _Loader is more robust.
\r
3328 * 7. SWT lazy loading is later introduced, which means that class loading
\r
3329 * process may be paused and should be resumed later.
\r
3331 * Some known bugs:
\r
3332 * <code>$_L(["$wt.graphics.Drawable","$wt.widgets.Widget"],
\r
3333 * "$wt.widgets.Control", ...</code>
\r
3334 * has errors while must classes in different order such as
\r
3335 * <code>$_L(["$wt.widgets.Widget", "$wt.graphics.Drawable"],
\r
3336 * "$wt.widgets.Control", ...</code>
\r
3339 * Other maybe bug scenarios:
\r
3340 * 1. In <code>_Loader.maxLoadingThreads = 1;</code> single loading thread
\r
3341 * mode, there are no errors, but in default multiple thread loading mode,
\r
3342 * there are errors.
\r
3343 * 2. No errors in one browser, but has errors on other browsers (Browser
\r
3344 * script loading order differences).
\r
3345 * 3. First time loading has errors, but reloading it gets no errors (Maybe
\r
3346 * HTTP connections timeout, but should not accur in local file system, or it
\r
3347 * is a loading bug by using JavaScript timeout thread).
\r
3351 * The following comments with "#" are special configurations for a much
\r
3352 * smaller *.js file size.
