Please see * this</a> page for a great description of the purpose of the AnalyzerGuru. * Created on September 22, 2005 * If you write your own analyzer please register it here * Initializes an AnalyzerGuru // TODO: have a comparator //System.err.println(analyzer.getSimpleName() + " = " + suffix); "suffix '" +

"' used in multiple analyzers";
// System.err.println("AnalyzerFinder:" + analyzer.getSimpleName() + e); //System.err.println(analyzer.getSimpleName() + " = " + magic); // System.err.println("AnalyzerFinder: " + analyzer.getSimpleName() + e); //System.err.println("Exts " + ext); //System.err.println("Matchers " + matchers); * Instruct the AnalyzerGuru to use a given analyzer for a given * @param extension the file-extension to add * @param analyzer the analyzer to use for the given extension * (if you pass null as the analyzer, you will disable * the analyzer used for that extension) * Get the default Analyzer. * Get an analyzer suited to analyze a file. This function will reuse * analyzers since they are costly. * @param in Input stream containing data to be analyzed * @param file Name of the file to be analyzed * @return An analyzer suited for that file content * @throws java.io.IOException If an error occurs while accessing the * data in the input stream. * Create a Lucene document and fill in the required fields * @param file The file to index * @param in The data to generate the index for * @param path Where the file is located (from source root) * @return The Lucene document to add to the index database * @throws java.io.IOException If an exception occurs while collecting the // date = hr.getLastCommentDate() //RFE // Ignoring any errors while analysing * Get the content type for a named file. * @param file The file to get the content type for * @return The contentType suitable for printing to response.setContentType() * Get the content type for a named file. * @param in The input stream we want to get the content type for (if * we cannot determine the content type by the filename) * @param file The name of the file * @return The contentType suitable for printing to response.setContentType() * @throws java.io.IOException If an error occurs while accessing the input * Get the content type the named analyzer accepts * @param analyzer the analyzer to test * @return the contentType suitable for printing to response.setContentType() * Write a browsable version of the file * @param analyzer The analyzer for this filetype * @param in The input stream containing the data * @param out Where to write the result * @param annotation Annotation information for the file * @throws java.io.IOException If an error occurs while creating the * Get the genre of a file * @param file The file to inpect * @return The genre suitable to decide how to display the file * Get the genre of a file (or the content of the file) * @param in The content of the file * @param file The file to inpect * @return The genre suitable to decide how to display the file * @throws java.io.IOException If an error occurs while getting the content * Get the genre of a bulk of data * @param in A stream containing the data * @return The genre suitable to decide how to display the file * @throws java.io.IOException If an error occurs while getting the content * Get the genre for a named class (this is most likely an analyzer) * @param clazz the class to get the genre for * @return The genre of this class (null if not found) * Finds a suitable analyser class for file name. If the analyzer cannot * be determined by the file extension, try to look at the data in the * InputStream to find a suitable analyzer. * Use if you just want to find file type. * @param in The input stream containing the data * @param file The file name to get the analyzer for * @return The analyzer to use * @throws java.io.IOException If a problem occurs while reading the data * Finds a suitable analyser class for file name. * @param file The file name to get the analyzer for * @return The analyzer to use //System.err.println(path.substring(dotpos+1).toUpperCase() + " = " + analyzer.getSimpleName()); // file doesn't have any of the extensions we know * Finds a suitable analyser class for the data in this stream * @param in The stream containing the data to analyze * @return The analyzer to use * @throws java.io.IOException if an error occurs while reading data from //System.out.println("USING = " + matcher.getName()); // cannot check conversion because of reflection * Finds a suitable analyser class for a magic signature * @param signature the magic signature look up * @return The analyzer to use * Get an analyzer by looking up the "magic signature" * @param signature the signature to look up * @return The analyzer to handle data with this signature
