Class Copies

java.lang.Object
  javax.print.attribute.IntegerSyntax
      javax.print.attribute.standard.Copies

All Implemented Interfaces:: Serializable, Cloneable, Attribute, PrintJobAttribute, PrintRequestAttribute

public final class Copies
extends IntegerSyntax
implements PrintRequestAttribute, PrintJobAttribute
extends IntegerSyntax
implements PrintRequestAttribute, PrintJobAttribute

Class Copies is an integer valued printing attribute class that specifies the number of copies to be printed.

On many devices the supported number of collated copies will be limited by the number of physical output bins on the device, and may be different from the number of uncollated copies which can be supported.

The effect of a Copies attribute with a value of n on a multidoc print job (a job with multiple documents) depends on the (perhaps defaulted) value of the MultipleDocumentHandling attribute:

SINGLE_DOCUMENT -- The result will be n copies of a single output document comprising all the input docs.
SINGLE_DOCUMENT_NEW_SHEET -- The result will be n copies of a single output document comprising all the input docs, and the first impression of each input doc will always start on a new media sheet.
SEPARATE_DOCUMENTS_UNCOLLATED_COPIES -- The result will be n copies of the first input document, followed by n copies of the second input document, . . . followed by n copies of the last input document.
SEPARATE_DOCUMENTS_COLLATED_COPIES -- The result will be the first input document, the second input document, . . . the last input document, the group of documents being repeated n times.

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

Constructor Detail

Copies

public Copies(int value)

Construct a new copies attribute with the given integer value.

Parameters:: value - Integer value.
Throws:: IllegalArgumentException - (Unchecked exception) Thrown if value is less than 1.

Method Detail

equals

public boolean equals(Object object)

Returns whether this copies 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 Copies.
This copies 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 copies attribute, false otherwise.
See Also:: Object.hashCode(), Hashtable

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 Copies, the category is class Copies 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 Copies, the category name is "copies".

Specified by:: getName in interface Attribute

Returns:: Attribute category name.
