Examples of PdfReference

org.apache.fop.pdf.PDFReference
Class representing a PDF object reference. The object holds a soft reference to the actual PDF object so the garbage collector can free the object if it's not referenced elsewhere. The important thing about the class is the reference information to the actual PDF object in the PDF file.
