Class CSVExporter
java.lang.Object
com.holub.database.CSVExporter
- All Implemented Interfaces:
- Table.Exporter
public class CSVExporter
- extends Object
- implements Table.Exporter
Pass this exporter to a Table.export(com.holub.database.Table.Exporter)
implementation to
create a comma-sparated-value version of a Table
.
For example:
Table people = TableFactory.create( ... );
//...
Writer out = new FileWriter( "people.csv" );
people.export( new CSVExporter(out) );
out.close();
The output file for a table called "name" with
columns "first," "last," and "addrId" would look
like this:
name
first, last, addrId
Fred, Flintstone, 1
Wilma, Flintstone, 1
Allen, Holub, 0
The first line is the table name, the second line
identifies the columns, and the subsequent lines define
the rows.
