public class CSVWriter

extends CSVHandler

Creates a CSV output from Maps each representing one row of the table. Before starting table creation, columns must be defined using putInValueType(). Additionally, column and decimal separator character can be set. They default to ";" and ".". Theses changes are not possible any more if output has started and the header has been written.
