- - org.apache.fop.pdf.PDFObject
  - - org.apache.fop.pdf.PDFPages

All Implemented Interfaces:
  PDFWritable

    public class PDFPages
    extends PDFObject

class representing a /Pages object. A /Pages object is an ordered collection of pages (/Page objects) (Actually, /Pages can contain further /Pages as well but this implementation doesn't allow this)

### Field Summary

Fields
`protected int` `count` the number of /Page objects
`protected List` `kids` the /Page objects

### Fields inherited from class org.apache.fop.pdf.PDFObject

`log`

### Constructor Summary

Constructor and Description
`PDFPages(PDFDocument document)` create a /Pages object.

### Method Summary

All Methods Instance Methods Concrete Methods
`void` `addPage(PDFPage page)` add a /Page object.
`int` `getCount()` get the count of /Page objects
`void` `incrementCount()` increment the count of /Page objects
`void` `notifyKidRegistered(PDFPage page)` Use this method to notify the PDFPages object that a child page
`String` `toPDFString()` This method returns a String representation of the PDF object.

### Field Detail

#### kids

    protected List kids

the /Page objects

#### count

    protected int count

the number of /Page objects

### Constructor Detail

#### PDFPages

    public PDFPages(PDFDocument document)

create a /Pages object. NOTE: The PDFPages object must be created before the PDF document is generated, but it is not written to the stream immediately. It must also be allocated an object ID (so that the kids can refer to the parent) so that the XRef table needs to be updated before this object is written.

### Method Detail

#### addPage

    public void addPage(PDFPage page)

add a /Page object.

Parameters:
  `page` - the PDFPage to add.

#### notifyKidRegistered

    public void notifyKidRegistered(PDFPage page)

Use this method to notify the PDFPages object that a child page

Parameters:
  `page` - the child page

#### getCount

    public int getCount()

get the count of /Page objects

Returns:
  the number of pages

#### incrementCount

    public void incrementCount()

increment the count of /Page objects

#### toPDFString

    public String toPDFString()

This method returns a String representation of the PDF object. The result is normally converted/encoded to a byte array by toPDF(). Only use this method to implement the serialization if the object can be fully represented as text. If the PDF representation of the object contains binary content use toPDF() or output(OutputStream) instead. This applies to any object potentially containing a string object because string object are encrypted and therefore need to be binary.

Overrides:
  `toPDFString` in class `PDFObject`
Returns:
  String the String representation
