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

Throws:

IFException - if an error occurs while handling this event

setupPDFSigning
