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

Description copied from interface: InternalLogger

msg - the message string to be logged

log

public void log(InternalLogLevel level,
                java.lang.String format,
                java.lang.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,
                java.lang.String format,
                java.lang.Object argA,
                java.lang.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,
                java.lang.String format,
                java.lang.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 java.lang.Object readResolve()
                                throws java.io.ObjectStreamException

Throws:

java.io.ObjectStreamException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
