# Class JobAttributes

java.lang.Object
java.awt.JobAttributes

All Implemented Interfaces:
  `Cloneable`

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.

  1.3

  - ### getPageRanges

    public int[][] getPageRanges()
    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.

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.

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

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.

  - ### 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.

      `toPage` - an integer greater than zero and greater than or equal to fromPage and greater than or equal to minPage and less than or equal to maxPage.
    Throws:
      `IllegalArgumentException` - if one or more of the above conditions is violated.

  - ### equals

    public boolean equals(Object obj)
    Determines whether two JobAttributes are equal to each other.

    Two JobAttributes are equal if and only if each of their attributes are equal. Attributes of enumeration type are equal if and only if the fields refer to the same unique enumeration object. A set of page ranges is equal if and only if the sets are of equal length, each range enumerates the same pages, and the ranges are in the same order.

    Overrides:
      `equals` in class `Object`
    Parameters:
      `obj` - the object whose equality will be checked.
    Returns:
      whether obj is equal to this JobAttribute according to the above criteria.
    See Also:
      - `Object.hashCode()`
      - `HashMap`

  - ### hashCode

    public int hashCode()
    Returns a hash code value for this JobAttributes.

    public String toString()
    Returns a string representation of this JobAttributes.
    Overrides:
      `toString` in class `Object`
    Returns:
      the string representation.
