/**
 * Facade class for filling compiled report designs with data from report data sources, 
 * in order to produce page-oriented documents, ready-to-print.
 * <p>
 * It exposes a variety of methods that receive a report template in the form of an object, file,
 * or input stream, and also produces a document in various output forms (object, file, or
 * output stream).
 * <p>
 * All methods receive a Map object that should contain the values for the report parameters.
 * These values are retrieved by the engine using the corresponding report parameter name as the key. 
 * <p>
 * There are two types of method signatures with regards to the data source
 * provided for filling the report:
 * <ul>
 * <li>Methods that receive an instance of the {@link net.sf.jasperreports.engine.JRDataSource} interface
 * and use it directly for retrieving report data;
 * <li>Methods that receive an instance of the <code>java.sql.Connection</code> interface and retrieve
 * the report data by executing the report internal SQL query through this JDBC connection and wrapping 
 * the returned <code>java.sql.ResultSet</code> object inside a {@link net.sf.jasperreports.engine.JRResultSetDataSource}
 * instance. 
 * </ul>
