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.

Constructor Detail

JobPriority

public JobPriority(int value)
Construct a new job priority attribute with the given integer value.

Parameters:
value - Integer value.
Throws:
IllegalArgumentException - (Unchecked exception) Thrown if value is less than 1 or greater than 100.
Method Detail

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.
