protected	JavaAnalyzer(AnalyzerFactory factory)	Creates a new instance of JavaAnalyzer.

Method Summary

Modifier and Type	Method	Description
String	getCtagsLang()	Subclasses should override to return the case-insensitive name aligning with either a built-in Universal Ctags language name or an OpenGrok custom language name.
protected int	getSpecializedVersionNo()	Gets a version number to be used to tag processed documents so that re-analysis can be re-done later if a stored version number is different from the current implementation.
