Class JobPriority

All Implemented Interfaces:
Serializable, Cloneable, Attribute, PrintJobAttribute, PrintRequestAttribute
public final class JobPriority
extends IntegerSyntax
implements PrintRequestAttribute, PrintJobAttribute
Class JobPriority is an integer valued printing attribute class that specifies a print job's priority.

If a JobPriority attribute is specified for a Print Job, it specifies a priority for scheduling the job. A higher value specifies a higher priority. The value 1 indicates the lowest possible priority. The value 100 indicates the highest possible priority. Among those jobs that are ready to print, a printer must print all jobs with a priority value of n before printing those with a priority value of n-1 for all n.

If the client does not specify a JobPriority attribute for a Print Job and the printer does support the JobPriority attribute, the printer must use an implementation-defined default JobPriority value.

The client can always specify any job priority value from 1 to 100 for a job. However, a Print Service instance may support fewer than 100 different job priority levels. If this is the case, the Print Service instance automatically maps the client-specified job priority value to one of the supported job priority levels, dividing the 100 job priority values equally among the available job priority levels.

IPP Compatibility: The integer value gives the IPP integer value. The category name returned by getName() gives the IPP attribute name.

      equals in class IntegerSyntax
      Parameters:
      object - Object to compare to
      Returns:
      true if object is equivalent to this job priority attribute, false otherwise

    • getCategory

      public final Class<? extends Attribute> getCategory()
      Get the printing attribute class which is to be used as the "category" for this printing attribute value.

      For class JobPriority, the category is class JobPriority itself.

      Specified by:
      getCategory in interface Attribute
      Returns:
      printing attribute class (category), an instance of class java.lang.Class

    • getName

      For class JobPriority, the category name is "job-priority".

      Specified by:
      getName in interface Attribute
      Returns:
      attribute category name
