Class Fop


  • public class Fop
    extends java.lang.Object
    Primary class that activates the FOP process for embedded usage.

    JAXP is the standard method of embedding FOP in Java programs. Please check our embedding page for samples (these are also available within the distribution in FOP_DIR\examples\embedding)

    Methods within FOUserAgent are available to customize portions of the process. For example, a specific Renderer object can be specified, also ElementMappings which determine elements in the FO that can be processed) can be added.

    At the moment, it is recommended not to reuse an instance of this class for more than one rendering run.

        Fop​(java.lang.String outputFormat,
            FOUserAgent ua,
            java.io.OutputStream stream)
        throws FOPException
        Constructor for use with already-created FOUserAgents. It uses MIME types to select the output format (ex. "application/pdf" for PDF).
        Parameters:
        outputFormat - the MIME type of the output format to use (ex. "application/pdf").
        ua - FOUserAgent object
        stream - the output stream
        Throws:
        FOPException - if setting up the DefaultHandler fails
    • Method Detail

      • getUserAgent

        public FOUserAgent getUserAgent()
        Deprecated.
        this getter doesn't need to exist. By virtue of the fact that the client has an instance of this object, it means they also have the FOUserAgent since this's constructor is only used in FOUserAgent
        Get the FOUserAgent instance associated with the rendering run represented by this instance.
        Returns:
        the user agent
      • createDefaultHandler

        private void createDefaultHandler()
                                   throws FOPException
        Creates a DefaultHandler object used to generate the document. Note this object implements the ContentHandler interface. For processing with a Transformer object, this DefaultHandler object can be used in the SAXResult constructor. Alternatively, for processing with a SAXParser, this object can be used as the DefaultHandler argument to its parse() methods.
        Throws:
        FOPException - if setting up the DefaultHandler fails
      • getDefaultHandler

        public org.xml.sax.helpers.DefaultHandler getDefaultHandler()
                                                             throws FOPException
        Returns the DefaultHandler object that will receive the SAX stream containing the FO document to be rendered.
        Returns:
        the SAX DefaultHandler for handling the SAX events.
        Throws:
        FOPException - if setting up the DefaultHandler fails
      • getResults

        public FormattingResults getResults()
        Returns the results of the rendering process. Information includes the total number of pages generated and the number of pages per page-sequence. Call this method only after the rendering process is finished. Note that the results are only available for output formats which make use of FOP's layout engine (PDF, PS, etc.).
        Returns:
        the results of the rendering process, or null for flow-oriented output formats like RTF and MIF.
