public class CSVExportProvider
extends PageableExportProvider

Provider, specialized for CSV data, which limits a wrapped table content-provider to exposing a specified set of properties; these properties are specified via binding expressions. The specialization involves providing column headers as the first row of data, using the column names specified by BoundPropertiesContentProvider.setKeys(java.util.Map).
