Method Detail

name

String name()

Return the name of this InternalLogger instance.

Returns:

name of this logger instance

isTraceEnabled

boolean isTraceEnabled()

Is the logger instance enabled for the TRACE level?

Returns:

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

trace

void trace(String msg)

Log a message at the TRACE level.

Parameters:

msg - the message string to be logged

trace

void trace(String format,
           Object arg)

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

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

Parameters:

format - the format string

arg - the argument

trace

void trace(String format,
           Object argA,
           Object argB)

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

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

Parameters:

format - the format string

argA - the first argument

argB - the second argument

trace

void trace(String format,
           Object... arguments)

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

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

Parameters:

format - the format string

arguments - a list of 3 or more arguments

trace

void trace(String msg,
           Throwable t)

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