JavaScript
// j2sjmol.js
// Java programming notes by Bob Hanson:
//
// There are a few motifs to avoid when optimizing Java code to work smoothly
// with the J2S compiler:
//
// arrays:
//
// 1. an array with null elements cannot be typed and must be avoided.
// 2. instances of Java "instance of" involving arrays must be found and convered to calls to Clazz.isA...
// 3. new int[n][] must not be used. Use instead JU.AU.newInt2(n);
// 4. new int[] { 1, 2, 3 } has problems because it creates simply [ ] and not IntArray32
//
// numbers:
//
// 1. Remember that EVERY number in JavaScript is a double -- doesn't matter if it is in IntArray32 or not.
// 2. You cannot reliably use Java long, because doubles consume bits for the exponent which cannot be tested.
// 3. Bit 31 of an integer is unreliable, since (int) -1 is now , not just 0zFFFFFFFF, and
// FFFFFFFF + 1 = 100000000, not 0. In JavaScript, 0xFFFFFFFF is 4294967295, not -1.
// This means that writeInt(b) will fail if b is negative. What you need is instead
// writeInt((int)(b & 0xFFFFFFFFl) so that JavaScript knocks off the high bits explicitly.
//
// general:
//
// 1. j2sRequireImport xxxx is needed if xxxx is a method used in a static function
// 2. URL.getContent() is not supported. Use other means based on URL.toString()
// 3. It is critical for performance to avoid any significant amount of function overloading.
// In particular, methods such as xxx(int a, int b) and xxx(float a, int b) MUST be renamed,
// because JavaScript only has Number, and there is absolutely no way to tell these apart.
// It's probably bad Java programming, anyway.
// 4. Calls to super(...) can almost always be avoided. These trigger the SAEM
// (searchAndExecuteMethod) call, and it is very destructive to performance.
// Just find another way to do it.
// NOTES by Bob Hanson:
// This version of j2slib requires jQuery and works in both Chrome and MSIE locally.
// J2S class changes:
// BH 6/1/2014 10:58:46 AM fix for Clazz.isAP() not working
// BH 5/26/2014 5:19:29 PM removing superConstructor call in creating Enum constants

// BH 4/1/2014 4:47:30 PM all $_X removed; this is taken care of by Google Closure Compiler

// BH 4/1/2014 6:40:08 AM removing ClassLoaderProgressMonitor -- equals ClazzLoaderProgressMonitor

// BH 12/3/2013 3:39:57 PM window["j2s.lib"].base implemented
// BH 12/1/2013 5:34:21 AM removed ClazzLoaderProgressMonitor.initialize and all Clazz.event business; handled by Jmol.clearVars()

// BH 11/29/2013 6:33:51 AM adding Clazz._profiler -- reports use of SAEM
// BH 11/10/2013 9:02:20 AM fixing fading in MSIE
// BH 11/3/2013 7:21:39 AM additional wrapping functions for better compressibility
// BH 10/30/2013 8:10:58 AM added getClass().getResource() -- returning a relative string, not a URL
// BH 10/30/2013 6:43:00 AM removed second System def and added System.$props and default System.property "line.separator"
// BH 6/15/2013 8:02:07 AM corrections to Class.isAS to return true if first element is null
// BH 6/14/2013 4:41:09 PM corrections to Clazz.isAI and related methods to include check for null object

// BH 2/27/2013 optimizing getParamsType for common cases () and (Number)
// BH 2/27/2013 optimizing SAEM delegation for hashCode and equals -- disallows overloading of equals(Object)

// BH 2/9/2013 9:18:03 PM Int32Array/Float64Array fixed for MSIE9
// BH 1/25/2013 1:55:31 AM moved package.js from j2s/java to j2s/core

// BH 1/17/2013 4:52:22 PM Int32Array and Float64Array may not have .prototype.sort method
// BH 1/16/2013 6:20:34 PM Float64Array not available in Safari 5.1
// BH 1/14/2013 11:28:58 PM Going to all doubles in JavaScript (Float64Array, not Float32Array)
// so that (new float[] {13.48f})[0] == 13.48f, effectively
// BH 1/14/2013 12:53:41 AM Fix for Opera 10 not loading any files
// BH 1/13/2013 11:50:11 PM Fix for MSIE not loading (nonbinary) files locally

// BH 11/21/2012 7:30:06 PM if (base != null) map["@" + pkg] = base; critical for multiple applets
// BH 10/8/2012 3:27:41 PM if (clazzName.indexOf("Array") >= 0) return "Array"; in Clazz.getClassName for function
// BH removed Clazz.ie$plit = "\\2".split (/\\/).length == 1; unnecessary; using RegEx slows process significantly in all browsers

* Make optimization over class dependency tree.
*/
/*
* ClassLoader Summary
*
* ClassLoader creates SCRIPT elements and setup class path and onload
* callback to continue class loading.
*
* In the onload callbacks, ClazzLoader will try to calculate the next-to-be-
* load *.js and load it. In *.js, it will contains some codes like
* Clazz.load (..., "$wt.widgets.Control", ...);
* to provide information to build up the class dependency tree.
*
* Some known problems of different browsers:
* 1. In IE, loading *.js through SCRIPT will first triggers onreadstatechange
* event, and then executes inner *.js source.
* 2. In Firefox, loading *.js will first executes *.js source and then
* triggers onload event.
* 3. In Opera, similar to IE, but trigger onload event. (TODO: More details
* should be studied. Currently, Opera supports no multiple-thread-loading)
*
* For class dependency tree, actually, it is not a tree. It is a reference
* net with nodes have n parents and n children. There is a root, which
* ClassLoader knows where to start searching and loading classes, for such
* a net. Each node is a class. Each class may require a set of must-classes,
* which must be loaded before itself getting initialized, and also need a set
* of optional classes, which also be loaded before being called.
*
* The class loading status will be in 6 stages.
* 1. Unknown, the class is newly introduced by other class.
* 2. Known, the class is already mentioned by other class.
* 3. Loaded, *.js source is in memory, but may not be initialized yet. It
* requires all its must-classes be intiailized, which is in the next stage.
* 4. Musts loaded, all must classes is already loaded and declared.
* 5. Delcared, the class is already declared (ClazzLoader#isClassDefined).
* 6. Optionals loaded, all optional classes is loaded and declared.
*
* The ClassLoader tries to load all necessary classes in order, and intialize
* them in order. For such job, it will traverse the dependency tree, and try
* to next class to-be-loaded. Sometime, the class dependencies may be in one
* or more cycles, which must be broken down so classes is loaded in correct
* order.
*
* Loading order and intializing order is very important for the ClassLoader.
* The following technical options are considered:
* 1. SCRIPT is loading asynchronously, which means controling order must use
* callback methods to continue.
* 2. Multiple loading threads are later introduced, which requires the
* ClassLoader should use variables to record the class status.
* 3. Different browsers have different loading orders, which means extra tests
* should be tested to make sure loading order won't be broken.
* 4. Java2Script simulator itself have some loading orders that must be
* honored, which means it should be integrated seamlessly to Clazz system.
* 5. Packed *.z.js is introduced to avoid lots of small *.js which requires
* lots of HTTP connections, which means that packed *.z.js should be treated
* specially (There will be mappings for such packed classes).
* 6. *.js or *.css loading may fail according to network status, which means
* another loading try should be performed, so ClazzLoader is more robust.
* 7. SWT lazy loading is later introduced, which means that class loading
* process may be paused and should be resumed later.
*
* Some known bugs:
* <code>$_L(["$wt.graphics.Drawable","$wt.widgets.Widget"],
* "$wt.widgets.Control", ...</code>
* has errors while must classes in different order such as
* <code>$_L(["$wt.widgets.Widget", "$wt.graphics.Drawable"],
* "$wt.widgets.Control", ...</code>
* has no error.
*
* Other maybe bug scenarios:
* 1. In <code>ClazzLoader.maxLoadingThreads = 1;</code> single loading thread
* mode, there are no errors, but in default multiple thread loading mode,
* there are errors.
* 2. No errors in one browser, but has errors on other browsers (Browser
* script loading order differences).
* 3. First time loading has errors, but reloading it gets no errors (Maybe
* HTTP connections timeout, but should not accur in local file system, or it
* is a loading bug by using JavaScript timeout thread).
