marker - the marker data specific to this log statement

format - the format string

arguments - a list of 3 or more arguments

warn

public void warn(Marker marker,
                 java.lang.String msg,
                 java.lang.Throwable t)

Description copied from interface: Logger

This method is similar to Logger.warn(String, Throwable) method except that the marker data is also taken into consideration.

Specified by:

warn in interface Logger

Parameters:

marker - the marker data for this log statement

msg - the message accompanying the exception

t - the exception (throwable) to log

isErrorEnabled

public boolean isErrorEnabled()

Description copied from interface: Logger

Is the logger instance enabled for the ERROR level?

Specified by:

isErrorEnabled in interface Logger

Returns:

True if this Logger is enabled for the ERROR level, false otherwise.

error

public void error(java.lang.String msg)

Description copied from interface: Logger

Log a message at the ERROR level.

Specified by:

error in interface Logger

Parameters:

msg - the message string to be logged

error

public void error(java.lang.String format,
                  java.lang.Object arg)

Description copied from interface: Logger

Log a message at the ERROR level according to the specified format and argument.

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

Specified by:

error in interface Logger

Parameters:

format - the format string

arg - the argument

error

public void error(java.lang.String format,
                  java.lang.Object arg1,
                  java.lang.Object arg2)

Description copied from interface: Logger

Log a message at the ERROR level according to the specified format and arguments.

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

Specified by:

error in interface Logger

Parameters:

format - the format string

arg1 - the first argument

arg2 - the second argument

error

public void error(java.lang.String format,
                  java.lang.Object... arguments)

Description copied from interface: Logger

Log a message at the ERROR level according to the specified format and arguments.

This form avoids superfluous string concatenation when the logger is disabled for the ERROR 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 ERROR. The variants taking one and two arguments exist solely in order to avoid this hidden cost.

Specified by:

error in interface Logger

Parameters:

format - the format string

arguments - a list of 3 or more arguments

error

public void error(java.lang.String msg,
                  java.lang.Throwable t)

Description copied from interface: Logger

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

Specified by:

error in interface Logger

Parameters:

msg - the message accompanying the exception

t - the exception (throwable) to log
