          public IFDocumentNavigationHandler getDocumentNavigationHandler()

      Returns a document navigation handler if this feature is supported.

    - #### startDocument

          public void startDocument()
                             throws IFException

      Indicates the start of a document. This method may only be called once before any other event method.
      Specified by:
        `startDocument` in interface `IFDocumentHandler`
      Overrides:
        `startDocument` in class `AbstractBinaryWritingIFDocumentHandler`

    - #### endDocumentHeader

          public void endDocumentHeader()
                                 throws IFException

      Indicates the end of the document header. This method is called before the first page sequence.
      Specified by:
        `endDocumentHeader` in interface `IFDocumentHandler`

                           throws IFException

      Indicates the end of a document. This method may only be called once after the whole document has been handled. Implementations can release resources (close streams). It is an error to call any event method after this method.
      Specified by:
        `endDocument` in interface `IFDocumentHandler`
      Overrides:
        `endDocument` in class `AbstractBinaryWritingIFDocumentHandler`

    - #### startPageSequence

          public void startPageSequence(String id)
                                 throws IFException

      Indicates the start of a new page sequence.
      Parameters:
        `id` - the page sequence's identifier (or null if none is available)
      Throws:
        `IFException` - if an error occurs while handling this event

    - #### endPageSequence
