public final class JobHoldUntil extends DateTimeSyntax implements PrintRequestAttribute, PrintJobAttributeClass
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
JOB_HOLD_UNTIL_SPECIFIEDto the job's
JobStateReasonsattribute, must move the job to the
PENDING_HELDstate, 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
JOB_HOLD_UNTIL_SPECIFIEDfrom the job's
JobStateReasonsattribute, if present. If there are no other job state reasons that keep the job in the
PENDING_HELDstate, 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
JobHoldUntilattribute 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
JobHoldUntilvalue at job submission time (unlike most job template attributes that are used if necessary at job processing time).
To construct a
JobHoldUntilattribute from separate values of the year, month, day, hour, minute, and so on, use a
Calendarobject to construct a
Dateobject, then use the
Dateobject to construct the
JobHoldUntilattribute. To convert a
JobHoldUntilattribute to separate values of the year, month, day, hour, minute, and so on, create a
Calendarobject and set it to 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
JobHoldUntilvalue 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.
