Package org.apache.uima.util.impl

Class Logger_impl

  • All Implemented Interfaces:
    Logger, org.slf4j.Logger
    public class Logger_impl
extends Logger_common_impl
    UIMA Logging interface implementation without using an logging toolkit Logger names are not used The call getInstance() returns a common shared instance. The call getInstance(String) ignores its argument but returns a new instance of this logger class. Each instance of this logger class can have a level set via the setAPI call - that is the only configuration possible. If not set, the level is INFO.

This version is called by all new logging statments that don't need to be backwards compatible. e.g. logger.info, logger.error, logger.warn, etc.

      • 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
