All Implemented Interfaces:

Class JobHoldUntil is 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 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 the 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 JobHoldUntil attribute.

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.

Method from javax.print.attribute.standard.JobHoldUntil Detail:
public boolean equals(Object object) { return (super.equals(object) && object instanceof JobHoldUntil); } Returns whether this job hold until attribute is equivalent to the passed in object. To be equivalent, all of the following conditions must be true: `object` is not null. `object` is an instance of class JobHoldUntil. This job hold until attribute's Date value and `object`'s Date value are equal.
public final Class<Attribute> getCategory() { return JobHoldUntil.class; } Get the printing attribute class which is to be used as the "category" for this printing attribute value. For class JobHoldUntil, the category is class JobHoldUntil itself.
public final String getName() { return "job-hold-until"; } Get the name of the category of which this attribute value is an instance. For class JobHoldUntil, the category name is `"job-hold-until"`.

 public boolean equals(Object object) {
        return (super.equals(object) && object instanceof JobHoldUntil);
}

object is not null.
object is an instance of class JobHoldUntil.
This job hold until attribute's Date value and object's Date value are equal.

 public final Class<Attribute> getCategory() {
        return JobHoldUntil.class;
}

For class JobHoldUntil, the category is class JobHoldUntil itself.

 public final String getName() {
        return "job-hold-until";
}

For class JobHoldUntil, the category name is "job-hold-until".
