DefaultLogger (XML Catalog Resolver API)

java.lang.Object
- org.xmlresolver.logging.AbstractLogger
- - org.xmlresolver.logging.DefaultLogger

All Implemented Interfaces:

ResolverLogger
```
public class DefaultLogger
extends AbstractLogger
```
The default logger logs to System.err.
By default, the DEFAULT_LOGGER_LOG_LEVEL feature determines which messages are logged. The valid levels are "debug", "info", "warn", and "none". An invalid level is treated as "warn".

If the level is set to "debug", all messages will be printed. If set to "info", info and warning messages will be printed. If set to "warn", only warning messages will be printed. If set to "none", no messages are printed.

If the configuration's DEFAULT_LOGGER_LOG_LEVEL is changed, that change will be detected by the logger and it will use that level going forward. The value can also be changed directly by calling setLogLevel(java.lang.String). That level will remain in effect as long as the configuration default does not change.
