Format the specified record as text. | ||||
The record's attribute dictionary is used as the operand to a | ||||
string formatting operation which yields the returned string. | ||||
Before formatting the dictionary, a couple of preparatory steps | ||||
are carried out. The message attribute of the record is computed | ||||
using LogRecord.getMessage(). If the formatting string uses the | ||||
time (as determined by a call to usesTime(), formatTime() is | ||||
called to format the event time. If there is exception information, | ||||
it is formatted using formatException() and appended to the message. | ||||
