Examples of LoggerStream

org.apache.logging.log4j.spi.LoggerStream
Output stream that logs each line written to a pre-defined level. Can also be configured with a Marker. This class provides an interface that follows the {@link java.io.PrintStream} methods in spirit, but doesn't output toany external stream. This class should not be used as a stream for an underlying logger unless it's being used as a bridge. Otherwise, infinite loops may occur!
org.jboss.logging.util.LoggerStream
A subclass of PrintStream that redirects its output to a log4j Logger.
This class is used to map PrintStream/PrintWriter oriented logging onto the log4j Categories. Examples include capturing System.out/System.err @version $Revision: 1455 $ @author Scott Stark. @author Jason Dillon

        stream.println("Debug message 1");

        stream.println();
        stream.println(); // verify blank log message
        stream.print("Debug message 3\n");
        stream.print("\r\n"); // verify windows EOL works
        assertEquals(5, results.size());
        assertThat("Incorrect message", results.get(0), startsWith(" DEBUG Debug message 1"));
        assertThat("Incorrect message", results.get(1), startsWith(" DEBUG Debug message 2"));
        assertEquals("Message should be blank-ish", " DEBUG ", results.get(2));
        assertThat("Incorrect message", results.get(3), startsWith(" DEBUG Debug message 3"));
