JavaScript Supported Types

org.eclipse.swt.browser.Browser.evaluate(String) and org.eclipse.swt.browser.BrowserFunction.execute(Object[]) methods send values back and forth between JavaScript and Java.

If the values being passed are types , types get converted.  The table below shows the type conversions that happen.  Attempts to pass an unsupported type will cause an SWTException.
