head
the
head string
returned from the target formatter and
finished by this formatter.
formatted
the current log record
formatted by
the target formatter and finished
by this formatter. If the formatter is null then record is formatted by
this formatter.
tail
the
tail string
returned from the target formatter and
finished by this formatter.
count
the total number of log records
consumed by this formatter.
remaining
the count minus one.
thrown
the total number of log records
consumed by this formatter with an assigned
throwable.
normal messages
the count minus the thrown.
minMillis
the eldest log record
event time
consumed by this formatter. If the count is zero
then this is set to the previous max or approximate start time if there
was no previous max. By default this parameter is defined as a number.
The format type and format style rules from the
MessageFormat should be used to convert this from
milliseconds to a date or time.
maxMillis
the most recent log record
event time
consumed by this formatter. If the count is zero
then this is set to the current time.
By default this parameter is defined as a number. The format type and
format style rules from the MessageFormat should be
used to convert this from milliseconds to a date or time.
elapsed
the elapsed time in milliseconds between the
maxMillis
and minMillis
.
startTime
the approximate start time in milliseconds. By
default this parameter is defined as a number. The format type and format
style rules from the MessageFormat should be used to
convert this from milliseconds to a date or time.
currentTime
the
current time in milliseconds. By
default this parameter is defined as a number. The format type and format
style rules from the MessageFormat should be used to
convert this from milliseconds to a date or time.
uptime
the elapsed time in milliseconds between the
currentTime
and startTime
.
generation
the number times this method produced output with
at least one consumed log record. This can be used
to track the number of complete reports this formatter has produced.
Some example formats:
com.sun.mail.util.logging.CollectorFormatter.format={0}{1}{2}{4,choice,-1#|0#|0<... {4,number,integer} more}\n
This prints the head ({0}
), format ({1}
), and tail
({2}
) from the target formatter followed by the number of
remaining ({4}
) log records consumed by this formatter if there
are any remaining records.

This prints the count ({3}
) followed by the date and time of the
eldest log record ({7}
) and the date and time of the most recent
log record ({8}
).
These 292 messages occurred between Tue, Jul 21 14:11:42:449 -0500 2009 and Fri, Nov 20 07:29:24:0 -0600 2009

This prints the count ({3}
) and then chooses the format based on
the elapsed time ({9}
). If the elapsed time is less than one day
then the eldest log record ({7}
) date and time is formatted
followed by just the time of the most recent log record ({8}
.
Otherwise, the just the date of the eldest log record ({7}
) and
just the date of most recent log record ({8}
is formatted.
