Class JavaIndexer

  • public final class JavaIndexer
extends java.lang.Object
    JavaIndexer provides functionality to generate index files which can be used by the JDT SearchEngine. The generated index files can be used as a classpath attribute for the particular classpath entry.

    The search engine indexes all the elements referred in the classpath entries of the project into index files. These index files are used to search the elements faster. Indexing for bigger jars could take some time. To avoid this time, one can generate the index file and specify it when the jar is added to the classpath of the project.
