/**
 * Returns a text edit that formats the given document according to the given settings.
 *
 * @param document/*from w w  w . j a va  2  s.  c  o m*/
 *            The document to format.
 * @param javaFormattingPrefs
 *            The formatting preferences for Java, used to determine the method level indentation.
 * @param javaScriptFormattingPrefs
 *            The formatting preferences for JavaScript. See org.eclipse.wst.jsdt.internal.formatter
 *            .DefaultCodeFormatterOptions and org.eclipse.wst.jsdt.core.formatter.DefaultCodeFormatterConstants
 * @param originalJsniMethods
 *            The original jsni methods to use if the formatter fails to format the method. The original jsni
 *            Strings must be in the same order that the jsni methods occur in the document. This is to work around
 *            the Java formatter blasting the jsni tabbing for the format-on-save action. May be null.
 * @return A text edit that when applied to the document, will format the jsni methods.
