/**
* All document exporting in JasperReports is done through this interface. There is an implementation of
* this interface for every document format that JasperReports supports at the moment.
*
* Export customization is realized by setting an ExporterConfiguration instance on the exporter and/or provide
* an instance of the same ExporterConfiguration interface for each item to be exported in batch mode using
* {@link ExporterInputItem#getConfiguration()}.
*
* An important aspect is the output type of each exporter. There are three types of exporters depending on
* the type of output they produce:
*
* - exporters that export to text or character based file formats (HTML, RTF, CSV, TXT, XML exporters);
*
- exporters that export to binary file formats (PDF and XLS exporters)
*
- exporters that export directly to graphic devices (Graphics2D and Java Print Service exporters)
*
*
* All existing exporters fall into two categories depending on the way the content of the documents they
* produce could be structured:
*
* - there are the exporters which target document formats which support free-form page content. These
* are the Grapchis2D, PDF, RTF and XML exporters.
*
- the second category of exporters groups those exporters that target document formats which only
* support relative positioning of elements on a page or a grid-based layout. In this category we have the
* HTML, XLS and CSV exporters.
