Specified by:

convert in interface Exporter<Object>

Parameters:

object - the table object to convert

outputStream - the output stream for the output file

Specified by:

setExportType in interface Exporter<Object>

Parameters:

exportType - the export type

setDecoder

public void setDecoder(String charsetName)
