APIs document

Currently, there are only one new package named net.sf.j2s.ajax, which contains about 1 interface and 6 classes:

• AClass
• ARunnable
• ASWTClass
• HttpRequest
• IXHRCallback
• XHRCallbackAdapter
• XHRCallbackSWTAdapter

The net.sf.j2s APIs are very simple. And you can ignore their existences until you are advanced users of asynchronous programming.

Here is the implemented Java runtime classes list, you should check the following Javadoc to see which APIs are already supported or not yet supported inside Java2Script.

• java.io
• java.lang
• java.lang.reflect
• java.util

Notice:Classes or interfaces "Class", "ClassLoader", "Object", "String", "Enum", "Number", "Integer", "Long", "Double", "Float" are implemented by native JavaScript are not mentioned in the above list.

The others APIs are not new in Java2Script.

• java.* (Entry of the above classes list)
• junit.*
• org.eclipse.swt.*

Language Supports

The features of Java2Script's Object Oriented JavaScript Simulator (OOJSS):

• Private modifier for both fields and methods are supported.
• Static modifier are supported
• Inner anonymous class instance creation are supported
• Polymorphism are supported
• Static intialization blocks are supported
• Other related Java inheritance simulation...

As this is a project related to converter that compiles Java to JavaScript. It will require you to know the defects that can not be compiled completely equivalent.

• double, float, long, int, short, byte, ... are all treated as Number in JavaScript
• All kinds of array are treated as simple Array type
• Static cyclic creation will fail
• Thread and synchronized are ignored
• More still need to be described ...
