LogService (SciJava Javadocs 0-SNAPSHOT API)

All Superinterfaces:

Comparable<Prioritized>, Contextual, Disposable, HasPluginInfo, Identifiable, Initializable, Locatable, Logged, Logger, Prioritized, RichPlugin, SciJavaPlugin, SciJavaService, Service, Versioned

All Known Implementing Classes:

AbstractLogService, SLF4JLogService, StderrLogService
```
public interface LogService
extends SciJavaService, Logger
```
Interface for the logging service.
The service supports five common logging levels: ERROR, WARN, INFO, TRACE and DEBUG. It is extensible to additional levels as needed. It provides methods for logging messages, exception stack traces and combinations of the two.

- Method Detail
  - setLevel
```
void setLevel(int level)
```
    Changes the log level of the root logger.
  - setLevel
```
void setLevel(String classOrPackageName,
              int level)
```
    For messages that are logged directly to the LogService. The log level can be set depending on the class that makes the log.
    
    Parameters:
    
    classOrPackageName - If this is the name of a class. Messages logged directly by this class are logged, if the message's level is less or equal to the given level. If this is a package, the same holds for all classes in this package.
    
    level - Given level.
  - setLevelForLogger
```
void setLevelForLogger(String source,
                       int level)
```
    Setting the log level for loggers depending on their LogSource. This will only affect loggers that are created after this method has been called.
