Package org.apache.uima.util.impl

Class Slf4jLogger_impl

  • All Implemented Interfaces:
    Logger, org.slf4j.Logger
    public class Slf4jLogger_impl
extends Logger_common_impl
    UIMA Logging interface implementation for SLF4j This design gets a logger in static initialization, in order to see what the back end is. If it is JUL or Log4j, it sets flags so that subsequent calls to getInstance gets those UIMA logger impls, not this one, in order to slightly reduce indirection at run time.

        public static int getSlf4jLevel​(Level level)

      • isLoggable

        public boolean isLoggable​(Level level)
        Description copied from interface: Logger
        Checks if the argument level is greater or equal to the specified level
        Parameters:
        level - message level
        Returns:
        boolean - true if the argument level is greater or equal to the specified level

      • isLoggable

        public boolean isLoggable​(Level level,
                          org.slf4j.Marker marker)
        Description copied from interface: Logger
        Checks if this logger is enabled for this level and this marker
        Parameters:
        level - the level to test
        marker - null or the marker to test
        Returns:
        true if the level is greater or equal to the specified level and the marker matches

      • setLevel

        public void setLevel​(Level level)
        Description copied from interface: Logger
        Sets the level of messages that will be logged by this logger. Note that if you call UIMAFramework.getLogger().setLevel(level), this will only change the logging level for messages produced by the UIMA framework. It will NOT change the logging level for messages produced by annotators. To change the logging level for an annotator, use UIMAFramework.getLogger(YourAnnotatorClass.class).setLevel(level).

        If you need more flexibility it configuring the logger, consider using the standard Java logger properties file or the java.util.logging APIs.

        Parameters:
        level - message level
