Class JDFiles


  • public class JDFiles
    extends java.lang.Object
    JDFiles - Documentation.

    This class is built inside a list of the file-names that are usually generated by the JavaDoc Utility. There are only two methods, but they are capable of retrieving the list of Java Doc Generated HTML Class Documentation Files - along with any package and page index information pages as well. Both of these methods only require a single parameter - the name of the directory that was used to output the JavaDoc Tool files.

    IMPORTANT NOTE: It is absolutely not mandatory to use these two methods to retrieve the names of Java Documentation Files, but primarily, because this class has relatively good amounts of documentation itself (is that... 'self-aware?'), generally if trying to remember the names of files like 'package-info.html' along with the parameters to the file-system search methods, referencing this page might be of use if anybody were trying to use these JavaDoc Extension and Updgrade Java Classes.




Stateless Class: This class neither contains any program-state, nor can it be instantiated.

      • getJavaClassHTMLFiles

        public static java.util.stream.Stream<java.lang.String> getJavaClassHTMLFiles​
                    (java.lang.String rootJDOutDirName)
        
        This method reads in the HTML files that JavaDoc generates for it's code documentation system, and returns the ones that are mapped to '.java' files. Classes in this Java-HTML package such as HTMLNode and FileNode make working witg HTML output, and file-system directory trees very easy.

        NOTE: This method accepts a directory name from the local file system. This must be the name of the directory to which the last call to javadoc left it's output HTML files
        Parameters:
        rootJDOutDirName - This should be the directory-name (as a String) of the last javadoc output directory. (Usually this is 'javadoc/')
        Returns:
        This will return the list of files as a Java Stream<String>.

             .createRoot(rootJDOutDirName)
             .loadTree(-1, HTML_FILE_FILTER, null)
             .flattenJustFiles(RetTypeChoice.FULLPATH_STREAM)
             .filter((String fileName) -> ! fileName.startsWith(rootJDOutDirName + "src-html" + File.separator))
             .filter((String fileName) -> ! fileName.startsWith(rootJDOutDirName + "index-files" + File.separator))
             .filter((String fileName) -> ! fileName.contains("package-summary.html"))
             .filter((String fileName) -> ! fileName.contains("package-tree.html"))
             .filter((String fileName) -> ! fileName.contains("package-frame.html"))
             .filter((String fileName) -> (StringParse.countCharacters(fileName, File.separator.charAt(0)) > 1));
                 // The previous filter prevents any ".html" files that are in the root java-doc output directory,
                 // ... and are not inside one of the packages.  If a class 'does not have a package' it will be skipped.
        
      • getSrcAsHTMLFiles

        public static java.util.stream.Stream<java.lang.String> getSrcAsHTMLFiles​
                    (java.lang.String rootJDOutDirName)
        
        This method reads in the HTML files which contain only the "Java Source Code" itself. The files that are returned in this Stream<String> are not "Code Documentation Web-Pages," but rather they are the "Java Source Code" itself, after some minor 'conversion' to turn them into HTML Web-Browser viewable files.

        NOTE: This method accepts a directory name from the local file system. This must be the name of the directory to which the last call to javadoc left it's output HTML files

        IMPORTANT: The 'javadoc' tool, by default, will not generate the "HTML-ized" source-code files. The creation of these files has to be specifically requested at the command-line using the switch -linksource. If this method is returning an empty Stream, make sure that the last invocation of jthe avadoc tool specified this switch, or there will not be a /jd-root-dir/src-file/ directory in the first place.
        Parameters:
        rootJDOutDirName - This should be the directory-name (as a String) of the last javadoc output directory. (Usually this is 'javadoc/')
        Returns:
        This will return the list of files as a Java Stream<String>.

                    (java.lang.String rootJDOutDirName)
        
        This method reads in the HTML files that JavaDoc generates for it's code documentation system, and returns all of the 'package-summary', 'package-tree', and 'package-frame' files, and essentially, every file which is left out of the results returned for method: getJavaClassHTMLFiles(String)

        NOTE: This method accepts a directory name from the local file system. This must be the name of the directory to which the last call to javadoc left it's output HTML files
