error

actual abstract fun error(msg: () -> Any?)
actual abstract fun error(marker: Marker?, msg: () -> Any?)

Lazy add a log message if isErrorEnabled is true

actual abstract fun error(t: Throwable?, msg: () -> Any?)
actual abstract fun error(marker: Marker?, t: Throwable?, msg: () -> Any?)

Lazy add a log message with throwable payload if isErrorEnabled is true

abstract fun error(msg: String?)

Log a message at the ERROR level.

Parameters

msg

the message string to be logged

abstract fun error(msg: String?, arg: Any?)

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

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

Parameters

msg

the msg string

arg

the argument

abstract fun error(msg: String?, arg1: Any?, arg2: Any?)

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

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

Parameters

msg

the msg string

arg1

the first argument

arg2

the second argument

abstract fun error(msg: String?, vararg arguments: Any?)

Log a message at the ERROR level according to the specified msg 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 .error and .error arguments exist solely in order to avoid this hidden cost.

Parameters

msg

the msg string

arguments

a list of 3 or more arguments

abstract fun error(msg: String?, t: Throwable?)

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

Parameters

msg

the message accompanying the exception

t

the exception (throwable) to log

abstract fun error(marker: Marker?, msg: String?)

Log a message with the specific Marker at the ERROR level.

Parameters

marker

The marker specific to this log statement

msg

the message string to be logged

abstract fun error(marker: Marker?, msg: String?, arg: Any?)

This method is similar to .error method except that the marker data is also taken into consideration.

Parameters

marker

the marker data specific to this log statement

msg

the msg string

arg

the argument

abstract fun error(marker: Marker?, msg: String?, arg1: Any?, arg2: Any?)

This method is similar to .error method except that the marker data is also taken into consideration.

Parameters

marker

the marker data specific to this log statement

msg

the msg string

arg1

the first argument

arg2

the second argument

abstract fun error(marker: Marker?, msg: String?, vararg arguments: Any?)

This method is similar to .error method except that the marker data is also taken into consideration.

Parameters

marker

the marker data specific to this log statement

msg

the msg string

arguments

a list of 3 or more arguments

abstract fun error(marker: Marker?, msg: String?, t: Throwable?)

This method is similar to .error method except that the marker data is also taken into consideration.

Parameters

marker

the marker data specific to this log statement

msg

the message accompanying the exception

t

the exception (throwable) to log

expect abstract fun error(msg: () -> Any?)

Lazy add a log message if isErrorEnabled is true

expect abstract fun error(t: Throwable?, msg: () -> Any?)

Lazy add a log message with throwable payload if isErrorEnabled is true

expect abstract fun error(marker: Marker?, msg: () -> Any?)

Lazy add a log message with a marker if isErrorEnabled is true

expect abstract fun error(marker: Marker?, t: Throwable?, msg: () -> Any?)

Lazy add a log message with a marker and throwable payload if isErrorEnabled is true
