There is a final class Nd in package internal.search.core.nd. I want to know how to use this data structure to store generated CompilationUnit and corresponding BindingResolver information(Not Java Model). I get CU and BR using JDT-parser as a standalone application.

Package internal.search.core.nd holds the implementation of the "new index". Have you seen the documentation at https://wiki.eclipse.org/JDT_Core_Index_Programmer_Guide ?

Note, that I don't know if that implementation really fits your purpose, but if you want to try it, the above documentation should be the best entry point.

I have already read the java index design google doc. But I see the java indexer is based on java model. And I have few problems for that.

Is it possible to build a java index out of Eclipse-plug environment（for example just from a target source folder）? Because I see the Indexer use

ResourcesPlugin.getWorkspace()

to scan the Eclipse workspace for initialization part. I want to know whether JDT provides other API to generate Indexer?
ASTParser provides two methods to build AST.

createASTs(ICompilationUnit[] compilationUnits, String[] bindingKeys, ASTRequestor requestor, IProgressMonitor monitor)

and

createASTs(String[] sourceFilePaths, String[] encodings, String[] bindingKeys,FileASTRequestor requestor, IProgressMonitor monitor)

my working environment is web application and that's why I hope Indexer can also have an alternative way to build like ASTParser. So I can use it as a standalone application instead of Eclipse-plugin application.
