Class LoggingOutputStream

java.lang.Object
java.io.OutputStream
org.terracotta.utilities.logging.LoggingOutputStream
All Implemented Interfaces:
Closeable, Flushable, AutoCloseable
public class LoggingOutputStream extends OutputStream
Implements an OutputStream that forwards lines written to it to a Logger at a specified level. Bytes are accumulated by this OutputStream until a System.lineSeparator() value is found; once the line ending is found, the line is flushed to the logger.

Bytes written to a LoggingOutputStream instance must have been encoded using UTF-8. This affects proper recognition of line separators and re-assembly of logged strings.
