Examples of com.google.common.io.LineReader

com.google.common.io.LineReader
A class for reading lines of text. Provides the same functionality as {@link java.io.BufferedReader#readLine()} but for all {@link Readable}objects, not just instances of {@link Reader}. @author Chris Nokleberg @since Guava release 01

    InputStreamReader input = new InputStreamReader(inputStream);
