PageRanges

public final class PageRanges extends SetOfIntegerSyntax implements PrintJobAttribute, PrintRequestAttribute, DocAttribute
Class PageRanges is a printing attribute class, a set of integers, that identifies the range(s) of print-stream pages that the Printer object uses for each copy of each document which are to be printed. Nothing is printed for any pages identified that do not exist in the document(s). The attribute is associated with print-stream pages, not application-numbered pages (for example, the page numbers found in the headers and or footers for certain word processing applications).

In most cases, the exact pages to be printed will be generated by a device driver and this attribute would not be required. However, when printing an archived document which has already been formatted, the end user may elect to print just a subset of the pages contained in the document. In this case, if a page range of "n-m" is specified, the first page to be printed will be page n. All subsequent pages of the document will be printed through and including page m.

If a PageRanges attribute is not specified for a print job, all pages of the document will be printed. In other words, the default value for the PageRanges attribute is always {{1, Integer.MAX_VALUE}}.

The effect of a PageRanges attribute on a multidoc print job (a job with multiple documents) depends on whether all the docs have the same page ranges specified or whether different docs have different page ranges specified, and on the (perhaps defaulted) value of the {@link MultipleDocumentHandling MultipleDocumentHandling} attribute.

  • If all the docs have the same page ranges specified, then any value of {@link MultipleDocumentHandling MultipleDocumentHandling} makes sense, and the printer's processing depends on the {@link MultipleDocumentHandling MultipleDocumentHandling} value:
    • SINGLE_DOCUMENT -- All the input docs will be combined together into one output document. The specified page ranges of that output document will be printed.

    • SINGLE_DOCUMENT_NEW_SHEET -- All the input docs will be combined together into one output document, and the first impression of each input doc will always start on a new media sheet. The specified page ranges of that output document will be printed.

    • SEPARATE_DOCUMENTS_UNCOLLATED_COPIES -- For each separate input doc, the specified page ranges will be printed.

    • SEPARATE_DOCUMENTS_COLLATED_COPIES -- For each separate input doc, the specified page ranges will be printed.
    • SEPARATE_DOCUMENTS_UNCOLLATED_COPIES -- For each separate input doc, its own specified page ranges will be printed..

    • SEPARATE_DOCUMENTS_COLLATED_COPIES -- For each separate input doc, its own specified page ranges will be printed..

IPP Compatibility: The PageRanges attribute's canonical array form gives the lower and upper bound for each range of pages to be included in and IPP "page-ranges" attribute. See class {@link javax.print.attribute.SetOfIntegerSyntax SetOfIntegerSyntax} for an explanation of canonical array form. The category name returned by getName() gives the IPP attribute name.

Fields Summary
private static final long
serialVersionUID
Constructors Summary
public PageRanges(int[] members)
Construct a new page ranges attribute with the given members. The members are specified in "array form;" see class {@link javax.print.attribute.SetOfIntegerSyntax SetOfIntegerSyntax} for an explanation of array form.

param
members Set members in array form.
exception
NullPointerException (unchecked exception) Thrown if members is null or any element of members is null.
exception
IllegalArgumentException (unchecked exception) Thrown if any element of members is not a length-one or length-two array. Also thrown if members is a zero-length array or if any member of the set is less than 1.


    
                                                                                                                                    
       
	super (members);
	if (members == null) {
	    throw new NullPointerException("members is null");
	}
	myPageRanges();
public PageRanges(String members)
Construct a new page ranges attribute with the given members in string form. See class {@link javax.print.attribute.SetOfIntegerSyntax SetOfIntegerSyntax} for explanation of the syntax.

param
members Set members in string form.
exception
NullPointerException (unchecked exception) Thrown if members is null or any element of members is null.
exception
IllegalArgumentException (Unchecked exception) Thrown if members does not obey the proper syntax. Also thrown if the constructed set-of-integer is a zero-length array or if any member of the set is less than 1.

	super(members);
	if (members == null) {
	    throw new NullPointerException("members is null");
	}
	myPageRanges();
public PageRanges(int member)
Construct a new page ranges attribute containing a single integer. That is, only the one page is to be printed.

param
member Set member.
exception
IllegalArgumentException (Unchecked exception) Thrown if member is less than 1.

	super (member);
	if (member < 1) {
	    throw new IllegalArgumentException("Page value < 1 specified");
	}
public PageRanges(int lowerBound, int upperBound)
Construct a new page ranges attribute containing a single range of integers. That is, only those pages in the one range are to be printed.

param
lowerBound Lower bound of the range.
param
upperBound Upper bound of the range.
exception
IllegalArgumentException (Unchecked exception) Thrown if a null range is specified or if a non-null range is specified with lowerBound less than 1.

	super (lowerBound, upperBound);
	if (lowerBound > upperBound) {
	    throw new IllegalArgumentException("Null range specified");
	} else if (lowerBound < 1) {
	    throw new IllegalArgumentException("Page value < 1 specified");
	}
Methods Summary
public booleanequals(java.lang.Object object)
Returns whether this page ranges 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 PageRanges.
  3. This page ranges attribute's members and object's members are the same.

param
object Object to compare to.
return
True if object is equivalent to this page ranges attribute, false otherwise.

	return (super.equals(object) && object instanceof PageRanges);
public final java.lang.ClassgetCategory()
Get the printing attribute class which is to be used as the "category" for this printing attribute value.

For class PageRanges, the category is class PageRanges itself.

return
Printing attribute class (category), an instance of class {@link java.lang.Class java.lang.Class}.

	return PageRanges.class;
public final java.lang.StringgetName()
Get the name of the category of which this attribute value is an instance.

For class PageRanges, the category name is "page-ranges".

return
Attribute category name.

	return "page-ranges";
