Examples of PushbackReader

java.io.PushbackReader
PushbackReader is a filter class which allows chars read to be pushed back into the stream so that they can be reread. Parsers may find this useful. There is a progammable limit to the number of chars which may be pushed back. If the buffer of pushed back chars is empty, chars are read from the source reader.

Examples of java.io.PushbackReader

        defineDecls = (String) defineDeclarations.get(filename);
      defineDecls = prependGlobalDefineDeclarations(defineDecls);


      try {
        CppFilterReader readIn = new CppFilterReader(in, defineDecls);
        Parser p = new Parser(new Lexer(new PushbackReader(readIn, 1024)));


        // Parse the file.
        Start tree = p.parse();


        // Apply the file loader.
