Package edu.illinois.ncsa.daffodil.japi.logger Description

Provides the classes necessary to recieve logging messages from Daffodil.

Overview

Daffodil comes with three prebuilt log writers:

• ConsoleLogWriter - writes all log messages to stdout
• FileLogWriter - writes all log messages to file
• NullLogWriter - drop all log messages

To use one of these log writers, create and instance of it and pass it to Daffodil.setLogWriter(edu.illinois.ncsa.daffodil.japi.logger.LogWriter). For example, to write all logs to /var/log/daffodil.log:

 
 FileLogWriter lw = new FileLogWriter(new File("/var/log/daffodil.log"));
 Daffodil.setLogWriter(lw);
 

One may also change the log level using Daffodil.setLoggingLevel(edu.illinois.ncsa.daffodil.japi.logger.LogLevel), which defaults to LogLevel.Info if not set. For example, to change the log level to LogLevel.Warning:

 
 Daffodil.setLoggingLevel(LogLevel.Warning);
