Class AbstractInternalLogger

java.lang.Object
io.micrometer.common.util.internal.logging.AbstractInternalLogger
All Implemented Interfaces:
InternalLogger, Serializable
public abstract class AbstractInternalLogger extends Object implements InternalLogger, Serializable
NOTE: This file has been copied and slightly modified from {io.netty.util.internal.logging}. A skeletal implementation of InternalLogger. This class implements all methods that have a InternalLogLevel parameter by default to call specific logger methods such as InternalLogger.info(String) or InternalLogger.isInfoEnabled().

      Parameters:
      level - log level

    • log

      public void log(InternalLogLevel level, String format, @Nullable Object arg)
      Description copied from interface: InternalLogger
      Log a message at the specified level according to the specified format and argument.

      This form avoids superfluous object creation when the logger is disabled for the specified level.

      Specified by:
      log in interface InternalLogger
      Parameters:
      level - log level
      format - the format string
      arg - the argument

    • log

      public void log(InternalLogLevel level, String format, @Nullable Object argA, @Nullable Object argB)
      Description copied from interface: InternalLogger
      Log a message at the specified level according to the specified format and arguments.

      This form avoids superfluous object creation when the logger is disabled for the specified level.

      Specified by:
      log in interface InternalLogger
      Parameters:
      level - log level
      format - the format string
      argA - the first argument
      argB - the second argument

    • log

      public void log(InternalLogLevel level, String format, @Nullable Object... arguments)
      Description copied from interface: InternalLogger
      Log a message at the specified level according to the specified format and arguments.

      This form avoids superfluous string concatenation when the logger is disabled for the specified level. However, this variant incurs the hidden (and relatively small) cost of creating an Object[] before invoking the method, even if this logger is disabled for the specified level. The variants taking one and two arguments exist solely in order to avoid this hidden cost.

      Specified by:
      log in interface InternalLogger
      Parameters:
      level - log level
      format - the format string
      arguments - a list of 3 or more arguments

    • readResolve

      protected Object readResolve() throws ObjectStreamException
      Throws:
      ObjectStreamException

    • toString

      public String toString()
      Overrides:
      toString in class Object
