 ### Overview
-Generally speaking, the LSIF for Java uses several **visitors** to visit the AST([Abstract Syntax Tree](https://www.eclipse.org/articles/article.php?file=Article-JavaCodeManipulation_AST/index.html)) and dump the index according to the [LSIF Specification](https://github.com/Microsoft/language-server-protocol/blob/master/indexFormat/specification.md).

 Major modules of the LSIF for Java are listed as follow:
-- [AST visitors](https://github.com/Microsoft/lsif-java/tree/master/com.microsoft.java.lsif.core/src/com/microsoft/java/lsif/core/internal/visitors)
-- [Language Server Index Format definitions](https://github.com/Microsoft/lsif-java/tree/master/com.microsoft.java.lsif.core/src/com/microsoft/java/lsif/core/internal/protocol)
-- [Components and utilities for indexing](https://github.com/Microsoft/lsif-java/tree/master/com.microsoft.java.lsif.core/src/com/microsoft/java/lsif/core/internal/indexer)

 The purpose of the Language Server Index Format (LSIF) is to define a standard format for language servers or other programming tools to dump their knowledge about a workspace. This dump can later be used to answer language server [LSP](https://microsoft.github.io/language-server-protocol/) requests for the same workspace without running the language server itself. Since much of the information would be invalidated by a change to the workspace, the dumped information typically excludes requests used when mutating a document. So, for example, the result of a code complete request is typically not part of such a dump.
