javax.print.attribute.standard.JobKOctets — clojure-interop/javax.print 1.0.5

Class JobKOctets is an integer valued printing attribute class that specifies the total size of the document(s) in K octets, i.e., in units of 1024 octets requested to be processed in the job. The value must be rounded up, so that a job between 1 and 1024 octets must be indicated as being 1K octets, 1025 to 2048 must be 2K octets, etc. For a multidoc print job (a job with multiple documents), the JobKOctets value is computed by adding up the individual documents' sizes in octets, then rounding up to the next K octets value.

The JobKOctets attribute describes the size of the job. This attribute is not intended to be a counter; it is intended to be useful routing and scheduling information if known. The printer may try to compute the JobKOctets attribute's value if it is not supplied in the Print Request. Even if the client does supply a value for the JobKOctets attribute in the Print Request, the printer may choose to change the value if the printer is able to compute a value which is more accurate than the client supplied value. The printer may be able to determine the correct value for the JobKOctets attribute either right at job submission time or at any later point in time.

The JobKOctets value must not include the multiplicative factors contributed by the number of copies specified by the Copies attribute, independent of whether the device can process multiple copies without making multiple passes over the job or document data and independent of whether the output is collated or not. Thus the value is independent of the implementation and indicates the size of the document(s) measured in K octets independent of the number of copies.

The JobKOctets value must also not include the multiplicative factor due to a copies instruction embedded in the document data. If the document data actually includes replications of the document data, this value will include such replication. In other words, this value is always the size of the source document data, rather than a measure of the hardcopy output to be produced.

The size of a doc is computed based on the print data representation class as specified by the doc's DocFlavor, as shown in the table below.

Representation Class Document Size

byte[] Length of the byte array

java.io.InputStream Number of bytes read from the stream

char[] Length of the character array x 2

java.lang.String Length of the string x 2

java.io.Reader Number of characters read from the stream x 2

java.net.URL Number of bytes read from the file at the given URL address

java.awt.image.renderable.RenderableImage Implementation dependent*

java.awt.print.Printable Implementation dependent*

java.awt.print.Pageable Implementation dependent*

• In these cases the Print Service itself generates the print data sent to the printer. If the Print Service supports the JobKOctets attribute, for these cases the Print Service itself must calculate the size of the print data, replacing any JobKOctets value the client specified.

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

->job-k-octets clj

(->job-k-octets value)

Constructor.

Construct a new job K octets attribute with the given integer value.

value - Integer value. - int

throws: java.lang.IllegalArgumentException - (Unchecked exception) Thrown if value is less than 0.

equals clj

(equals this object)

Returns whether this job K octets 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 JobKOctets.

This job K octets attribute's value and object's value are equal.

object - Object to compare to. - java.lang.Object

returns: True if object is equivalent to this job K octets attribute, false otherwise. - boolean

get-category clj

(get-category this)

Get the printing attribute class which is to be used as the "category" for this printing attribute value.

For class JobKOctets, the category is class JobKOctets itself.

returns: Printing attribute class (category), an instance of class java.lang.Class. - java.lang.Class<? extends javax.print.attribute.Attribute>

get-name clj

(get-name this)

Get the name of the category of which this attribute value is an instance.

For class JobKOctets, the category name is "job-k-octets".

returns: Attribute category name. - java.lang.String
