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

        public boolean equals(Object object)
        Returns whether this job priority attribute is equivalent to the passed in object. To be equivalent, all of the following conditions must be true:
        1. object is not null.
        2. object is an instance of class JobPriority.
        3. This job priority attribute's value and object's value are equal.
        Overrides:
        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

        public final String getName()
        Get the name of the category of which this attribute value is an instance.

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

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