/**
* Exports a JasperReports document to ODF format. It has character output type and exports the document to a
* grid-based layout.
*
* Open Document Format (short for OASIS Open Document Format for Office
* Applications) describes electronic documents such as memos, spreadsheets, books,
* charts, presentations, and word processing documents. .odt is the
* file extension used for the word processing documents in the Open Document Format, and such
* files can be obtained in JasperReports using the
* {@link net.sf.jasperreports.engine.export.oasis.JROdtExporter} class.
*
* Currently, there are the following special configurations that can be applied to an ODT
* exporter instance (see {@link net.sf.jasperreports.export.DocxReportConfiguration}) to customize
* its behavior:
*
* Allowing table rows to adjust their height if more text is typed into their cells using
* the ODT editor. This is controlled using either the
* {@link net.sf.jasperreports.export.OdtReportConfiguration#isFlexibleRowHeight() isFlexibleRowHeight()}
* exporter configuration flag, or its corresponding exporter hint called
* {@link net.sf.jasperreports.export.OdtReportConfiguration#PROPERTY_ODT_FLEXIBLE_ROW_HEIGHT net.sf.jasperreports.export.odt.flexible.row.height}.
* Ignoring hyperlinks in generated documents if they are not intended for the ODT output format. This can be
* customized using either the
* {@link net.sf.jasperreports.export.OdtReportConfiguration#isIgnoreHyperlink() isIgnoreHyperlink()}
* exporter configuration flag, or its corresponding exporter hint called
* {@link net.sf.jasperreports.export.OdtReportConfiguration#PROPERTY_IGNORE_HYPERLINK net.sf.jasperreports.export.odt.ignore.hyperlink}
*
*
* So far, the ODT exporter has the known limitations of grid exporters. It
* can work in batch mode and supports all types of exporter input and output as well as
* font mappings.
