public final class JobHoldUntil extends DateTimeSyntax implements PrintRequestAttribute, PrintJobAttribute
JobHoldUntilis a printing attribute class, a date-time attribute, that specifies the exact date and time at which the job must become a candidate for printing.
If the value of this attribute specifies a date-time that is in the future,
the printer should add the
JobStateReason value of
JOB_HOLD_UNTIL_SPECIFIED to the job's
JobStateReasons attribute, must move the job to the
PENDING_HELD state, and must not schedule the job for printing until
the specified date-time arrives.
When the specified date-time arrives, the printer must remove the
JobStateReason value of
JOB_HOLD_UNTIL_SPECIFIED from the job's
JobStateReasons attribute, if present. If there are
no other job state reasons that keep the job in the
state, the printer must consider the job as a candidate for processing by
moving the job to the PENDING state.
If the specified date-time has already passed, the job must be a candidate
for processing immediately. Thus, one way to make the job immediately become
a candidate for processing is to specify a
constructed like this
(denoting a date-time of January 1, 1970, 00:00:00 GMT):
JobHoldUntil immediately = new JobHoldUntil (new Date (0L));
If the client does not supply this attribute in a Print Request and the
printer supports this attribute, the printer must use its
JobHoldUntil value at job
submission time (unlike most job template attributes that are used if
necessary at job processing time).
To construct a
JobHoldUntil attribute from separate values of the
year, month, day, hour, minute, and so on, use a
object to construct a
Date object, then use the
Date object to construct the
JobHoldUntil attribute. To
JobHoldUntil attribute to separate values of the year,
month, day, hour, minute, and so on, create a
object and set it to the
Date from the
IPP Compatibility: Although IPP supports a "job-hold-until" attribute
specified as a keyword, IPP does not at this time support a "job-hold-until"
attribute specified as a date and time. However, the date and time can be
converted to one of the standard IPP keywords with some loss of precision;
for example, a
JobHoldUntil value with today's date and 9:00pm local
time might be converted to the standard IPP keyword "night". The category
name returned by
getName() gives the IPP attribute name.
