Class VoidLogger

  • All Implemented Interfaces:
    Logger
    @Deprecated
public class VoidLogger
extends Object
implements Logger
    Deprecated.
    starting with 3.1M2 use SLF4J's NOPLogger instead: NOPLogger.NOP_LOGGER
    Logger that doesn't do anything. Useful to use when no logger implementation is selected to prevent NPEs. In a component-based environment loggers are always set but when component classes are used as simple Java Beans the logger needs to be set and this logger implementation can be used when the user doesn't set explicitly a logger.
