      • getProcessingOrder

        public int getProcessingOrder()
        Returns a relatively low processing order indicating this BundleWriterHandler should be one of the first processed. This is due to the fact that any Resource which is writen into the DocumentBundle will cause the report's definition to be modified with a new Resource Key.
        Specified by:
        getProcessingOrder in interface BundleWriterHandler
        the relative processing order for this BundleWriterHandler
      • writeReport

        public String writeReport​(org.pentaho.reporting.libraries.docbundle.WriteableDocumentBundle bundle,
                                  BundleWriterState state)
                           throws IOException,
        Writes a certain aspect into a own file. The name of file inside the bundle is returned as string. The file name returned is always absolute and can be made relative by using the IOUtils of LibBase. If the writer-handler did not generate a file on its own, it should return null.
        Specified by:
        writeReport in interface BundleWriterHandler
        bundle - the bundle where to write to.
        state - the writer state to hold the current processing information.
        the name of the newly generated file or null if no file was created.
        IOException - if any error occured
        BundleWriterException - if a bundle-management error occured.
