Example 1 with JavadocLexer

use of com.puppycrawl.tools.checkstyle.grammars.javadoc.JavadocLexer in project checkstyle by checkstyle.

the class JavadocDetailNodeParser method parseJavadocAsParseTree.

/**
     * Parses block comment content as javadoc comment.
     * @param blockComment
     *        block comment content.
     * @return parse tree
     */
private ParseTree parseJavadocAsParseTree(String blockComment) {
    final ANTLRInputStream input = new ANTLRInputStream(blockComment);
    final JavadocLexer lexer = new JavadocLexer(input);
    // remove default error listeners
    lexer.removeErrorListeners();
    // add custom error listener that logs parsing errors
    lexer.addErrorListener(errorListener);
    final CommonTokenStream tokens = new CommonTokenStream(lexer);
    final JavadocParser parser = new JavadocParser(tokens);
    // remove default error listeners
    parser.removeErrorListeners();
    // add custom error listener that logs syntax errors
    parser.addErrorListener(errorListener);
    // This strategy stops parsing when parser error occurs.
    // By default it uses Error Recover Strategy which is slow and useless.
    parser.setErrorHandler(new BailErrorStrategy());
    return parser.javadoc();
}

Example 2 with JavadocLexer

use of com.puppycrawl.tools.checkstyle.grammars.javadoc.JavadocLexer in project contribution by checkstyle.

the class ExpectedParseTreeGenerator method parseJavadocFromFile.

private static ParseTree parseJavadocFromFile(File file) throws IOException {
    final String content = Files.toString(file, Charsets.UTF_8);
    final InputStream in = new ByteArrayInputStream(content.getBytes(Charsets.UTF_8));
    final ANTLRInputStream input = new ANTLRInputStream(in);
    final JavadocLexer lexer = new JavadocLexer(input);
    lexer.removeErrorListeners();
    final BaseErrorListener errorListener = new FailOnErrorListener();
    lexer.addErrorListener(errorListener);
    final CommonTokenStream tokens = new CommonTokenStream(lexer);
    final JavadocParser parser = new JavadocParser(tokens);
    parser.removeErrorListeners();
    parser.addErrorListener(errorListener);
    return parser.javadoc();
