public final class JobHoldUntil extends DateTimeSyntax implements PrintRequestAttribute, PrintJobAttribute
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
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
JobStateReasons attribute, if present. If there
are no other job state reasons that keep the job in the PENDING_HELD 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 JobHoldUntil attribute 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 (implementation-dependent) default 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
Calendar object to construct a
Date object, then use
Date object to construct the JobHoldUntil
attribute. To convert a JobHoldUntil attribute to separate values of the
year, month, day, hour, minute, and so on, create a
Calendar 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
getName() gives the IPP attribute name.

Returns whether this job hold until attribute is equivalent to the passed in object.
