Package org.apache.log4j

Class Category

  • Direct Known Subclasses:
    Logger
    @Deprecated(since="2022-01-27")
public class Category
extends java.lang.Object
    Deprecated.
    Apache Log4j 1 has reached end of life in 2015 and is no longer supported.

    This class is a minimal implementation of the original org.apache.log4j.Category class (as found in log4j 1.2) by delegation of all calls to a Logger instance.

    Log4j's trace, debug(), info(), warn(), error() printing methods are directly mapped to their SLF4J equivalents. Log4j's fatal() printing method is mapped to SLF4J's error() method with a FATAL marker.

        Deprecated.
        Delegates to Logger.isDebugEnabled() method in SLF4J

      • isInfoEnabled

        public boolean isInfoEnabled()
        Deprecated.
        Delegates to Logger.isInfoEnabled() method in SLF4J

        public boolean isEnabledFor​(Priority p)
        Deprecated.
        Determines whether the priority passed as parameter is enabled in the underlying SLF4J logger. Each log4j priority is mapped directly to its SLF4J equivalent, except for FATAL which is mapped as ERROR.
        Parameters:
        p - the priority to check against

        true if this logger is enabled for the given level, false otherwise.
