    lexer.removeErrorListeners();
    lexer.addErrorListener(syntaxError);
    CommonTokenStream tokens = new CommonTokenStream(lexer);
    BeetlParser parser = new BeetlParser(tokens);
    // 测试代码
    parser.setErrorHandler(antlrErrorStrategy);
    // 
    ProgContext tree = parser.prog();
    // begin parsing at init rule
    AntlrProgramBuilder pb = getAntlrBuilder(gt);
    ProgramMetaData data = pb.build(tree);
    Program program = new Program();
    program.metaData = data;
    program.res = resource;
    program.rs = resource;
    program.gt = gt;
    program.metaData.staticTextArray = new Object[textMap.size()];
    program.metaData.lineSeparator = cr;
    int i = 0;
    Configuration conf = gt.getConf();
    String charset = conf.getCharset();
    boolean byteOut = conf.isDirectByteOutput();
    for (Entry<Integer, String> entry : textMap.entrySet()) {
        if (byteOut) {
            try {
                program.metaData.staticTextArray[i++] = entry.getValue().getBytes(charset);
            } catch (UnsupportedEncodingException e) {
                throw new RuntimeException(e);
            }
        } else {
            program.metaData.staticTextArray[i++] = entry.getValue().toCharArray();
        }
    }
    return program;
}

Example 2 with ProgramMetaData

}

Example 3 with ProgramMetaData

use of org.beetl.core.statement.ProgramMetaData in project beetl2.0 by javamonkey.

the class FastRuntimeEngine method createProgram.

@Override
public Program createProgram(Resource rs, Reader reader, Map<Integer, String> textMap, String cr, GroupTemplate gt) {
    Program orginalProgram = super.createProgram(rs, reader, textMap, cr, gt);
    // copy 一个出来分析
    ProgramMetaData metaData = orginalProgram.metaData.copy();
    Program copyProgram = new Program();
    copyProgram.metaData = metaData;
    copyProgram.res = orginalProgram.res;

    TypeBindingProbe firstFilter = new TypeBindingProbe(copyProgram, nextFilter);
    // 在能优化前，按照原有的program执行，但每次都会执行fitler以看看是否能优化
    FilterProgram filterProgram = new FilterProgram(orginalProgram, copyProgram, firstFilter);
    return filterProgram;
