Class JobAttributes

public final class JobAttributes
extends Object
implements Cloneable

A set of attributes which control a print job.

Instances of this class control the number of copies, default selection, destination, print dialog, file and printer names, page ranges, multiple document handling (including collation), and multi-page imposition (such as duplex) of every print job which uses the instance. Attribute names are compliant with the Internet Printing Protocol (IPP) 1.1 where possible. Attribute values are partially compliant where possible.

To use a method which takes an inner class type, pass a reference to one of the constant fields of the inner class. Client code cannot create new instances of the inner class types because none of those classes has a public constructor. For example, to set the print dialog type to the cross-platform, pure Java print dialog, use the following code:

import java.awt.JobAttributes;

 public class PureJavaPrintDialogExample {
     public void setPureJavaPrintDialog(JobAttributes jobAttributes) {
         jobAttributes.setDialog(JobAttributes.DialogType.COMMON);
     }
 }

Every IPP attribute which supports an attributeName-default value has a corresponding setattributeNameToDefault method. Default value fields are not provided.

JobAttributes

public JobAttributes(int copies,
                     JobAttributes.DefaultSelectionType defaultSelection,
                     JobAttributes.DestinationType destination,
                     JobAttributes.DialogType dialog,
                     String fileName,
                     int maxPage,
                     int minPage,
                     JobAttributes.MultipleDocumentHandlingType multipleDocumentHandling,
                     int[][] pageRanges,
                     String printer,
                     JobAttributes.SidesType sides)

Constructs a JobAttributes instance with the specified values for every attribute.

Parameters:

copies - an integer greater than 0

defaultSelection - DefaultSelectionType.ALL, DefaultSelectionType.RANGE, or DefaultSelectionType.SELECTION

destination - DesintationType.FILE or DesintationType.PRINTER

dialog - DialogType.COMMON, DialogType.NATIVE, or DialogType.NONE

fileName - the possibly null file name

maxPage - an integer greater than zero and greater than or equal to minPage

minPage - an integer greater than zero and less than or equal to maxPage

multipleDocumentHandling - MultipleDocumentHandlingType.SEPARATE_DOCUMENTS_COLLATED_COPIES or MultipleDocumentHandlingType.SEPARATE_DOCUMENTS_UNCOLLATED_COPIES

pageRanges - an array of integer arrays of two elements; an array is interpreted as a range spanning all pages including and between the specified pages; ranges must be in ascending order and must not overlap; specified page numbers cannot be less than minPage nor greater than maxPage; for example:

(new int[][] { new int[] { 1, 3 }, new int[] { 5, 5 },
                         new int[] { 15, 19 } }),

specifies pages 1, 2, 3, 5, 15, 16, 17, 18, and 19. Note that (new int[][] { new int[] { 1, 1 }, new int[] { 1, 2 } }), is an invalid set of page ranges because the two ranges overlap

printer - the possibly null printer name

sides - SidesType.ONE_SIDED, SidesType.TWO_SIDED_LONG_EDGE, or SidesType.TWO_SIDED_SHORT_EDGE

Throws:

IllegalArgumentException - if one or more of the above conditions is violated

setFromPage

public void setFromPage(int fromPage)

If this attribute is not specified, then the values from the pageRanges attribute are used. If pageRanges and either or both of fromPage and toPage are specified, pageRanges takes precedence. Specifying none of pageRanges, fromPage, or toPage is equivalent to calling setPageRanges(new int[][] { new int[] { minPage } });

An application should ignore this attribute on output, unless the return value of the getDefaultSelection method is DefaultSelectionType.RANGE.

Returns:

an array of integer arrays of 2 elements. An array is interpreted as a range spanning all pages including and between the specified pages. Ranges must be in ascending order and must not overlap. Specified page numbers cannot be less than minPage nor greater than maxPage. For example: (new int[][] { new int[] { 1, 3 }, new int[] { 5, 5 }, new int[] { 15, 19 } }), specifies pages 1, 2, 3, 5, 15, 16, 17, 18, and 19.

setPageRanges

public void setPageRanges(int[][] pageRanges)

Specifies, for jobs using these attributes, the ranges of pages to be printed, if a range of pages is to be printed. All range numbers are inclusive. If this attribute is not specified, then the values from the fromPage and toPages attributes are used. If pageRanges and either or both of fromPage and toPage are specified, pageRanges takes precedence. Specifying none of pageRanges, fromPage, or toPage is equivalent to calling setPageRanges(new int[][] { new int[] { minPage, minPage } });

Parameters:

pageRanges - an array of integer arrays of 2 elements. An array is interpreted as a range spanning all pages including and between the specified pages. Ranges must be in ascending order and must not overlap. Specified page numbers cannot be less than minPage nor greater than maxPage. For example: (new int[][] { new int[] { 1, 3 }, new int[] { 5, 5 }, new int[] { 15, 19 } }), specifies pages 1, 2, 3, 5, 15, 16, 17, 18, and 19. Note that (new int[][] { new int[] { 1, 1 }, new int[] { 1, 2 } }), is an invalid set of page ranges because the two ranges overlap.

Throws:

IllegalArgumentException - if one or more of the above conditions is violated.

getPrinter

public String getPrinter()

Returns the destination printer for jobs using these attributes. This attribute is updated to the value chosen by the user.

Returns:

the possibly null printer name.

setPrinter

public void setPrinter(String printer)

Specifies the destination printer for jobs using these attributes. Default is platform-dependent and implementation-defined.

Parameters:

printer - the possibly null printer name.

getSides

public JobAttributes.SidesType getSides()

Returns how consecutive pages should be imposed upon the sides of the print medium for jobs using these attributes. SidesType.ONE_SIDED imposes each consecutive page upon the same side of consecutive media sheets. This imposition is sometimes called simplex. SidesType.TWO_SIDED_LONG_EDGE imposes each consecutive pair of pages upon front and back sides of consecutive media sheets, such that the orientation of each pair of pages on the medium would be correct for the reader as if for binding on the long edge. This imposition is sometimes called duplex. SidesType.TWO_SIDED_SHORT_EDGE imposes each consecutive pair of pages upon front and back sides of consecutive media sheets, such that the orientation of each pair of pages on the medium would be correct for the reader as if for binding on the short edge. This imposition is sometimes called tumble. This attribute is updated to the value chosen by the user.

Returns:

SidesType.ONE_SIDED, SidesType.TWO_SIDED_LONG_EDGE, or SidesType.TWO_SIDED_SHORT_EDGE.

setSides

public void setSides(JobAttributes.SidesType sides)

Specifies how consecutive pages should be imposed upon the sides of the print medium for jobs using these attributes. SidesType.ONE_SIDED imposes each consecutive page upon the same side of consecutive media sheets. This imposition is sometimes called simplex. SidesType.TWO_SIDED_LONG_EDGE imposes each consecutive pair of pages upon front and back sides of consecutive media sheets, such that the orientation of each pair of pages on the medium would be correct for the reader as if for binding on the long edge. This imposition is sometimes called duplex. SidesType.TWO_SIDED_SHORT_EDGE imposes each consecutive pair of pages upon front and back sides of consecutive media sheets, such that the orientation of each pair of pages on the medium would be correct for the reader as if for binding on the short edge. This imposition is sometimes called tumble. Not specifying this attribute is equivalent to specifying SidesType.ONE_SIDED.

Sets how consecutive pages should be imposed upon the sides of the print medium for jobs using these attributes to the default. The default imposition is SidesType.ONE_SIDED.

getToPage

public int getToPage()

Returns, for jobs using these attributes, the last page (inclusive) to be printed, if a range of pages is to be printed. This attribute is updated to the value chosen by the user. An application should ignore this attribute on output, unless the return value of the getDefaultSelection method is DefaultSelectionType.RANGE. An application should honor the return value of getPageRanges over the return value of this method, if possible.

an integer greater than zero and greater than or equal to toPage and greater than or equal to minPage and less than or equal to maxPage.

setToPage

public void setToPage(int toPage)
