Class AbstractInternalLogger

java.lang.Object

io.micrometer.core.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().

error

public void error(Throwable t)

Description copied from interface: InternalLogger

Specified by:

error in interface InternalLogger

Parameters:

t - the exception (throwable) to log

log

public void log(InternalLogLevel level,
                String msg,
                Throwable cause)

Description copied from interface: InternalLogger

Log an exception (throwable) at the specified level with an accompanying message.

msg - the message accompanying the exception

cause - the exception (throwable) to log

log

public void log(InternalLogLevel level,
                Throwable cause)

Description copied from interface: InternalLogger

Log an exception (throwable) at the specified level.

Specified by:

log in interface InternalLogger

cause - the exception (throwable) to log

log

public void log(InternalLogLevel level,
                String msg)

Description copied from interface: InternalLogger

Log a message at the specified level.

Specified by:

log in interface InternalLogger

msg - the message string to be logged

log

public void log(InternalLogLevel level,
                String format,
                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

format - the format string

arg - the argument

log

public void log(InternalLogLevel level,
                String format,
                Object argA,
                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

format - the format string

argA - the first argument

argB - the second argument

log

public void log(InternalLogLevel level,
                String format,
                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

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
