## org.apache.fop.pdf
Class PDFPages

    java.lang.Object
      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
`protected int` | `count` the number of /Page objects
`protected java.util.List` | `kids` the /Page objects

Fields inherited from class org.apache.fop.pdf.PDFObject
`DATE_FORMAT, log`

Constructor Summary
`PDFPages(int objnum)` create a /Pages object.

Method Summary
`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
`java.lang.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.

Field Detail

### kids

    protected java.util.List kids

  the /Page objects

### count

    protected int count

  the number of /Page objects

Constructor Detail

### PDFPages

    public PDFPages(int objnum)

  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.

Parameters:
  `objnum` - the object's number

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 java.lang.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
