Method Detail

convertReportData

public static net.sf.jasperreports.engine.JRDataSource convertReportData(Object value)

Convert the given report data value to a JRDataSource.

In the default implementation, a JRDataSource, java.util.Collection or object array is detected. The latter are converted to JRBeanCollectionDataSource or JRBeanArrayDataSource, respectively.

Parameters:

value - the report data value to convert

Returns:

the JRDataSource

Throws:

IllegalArgumentException - if the value could not be converted
