public class JRCsvMetadataExporter
extends JRAbstractCsvExporter

Exports a JasperReports document to CSV format based on the metadata provided.

The exporter allows users to specify which columns should be included in the CSV export, what other value than the default should they contain and whether the values for some columns should be auto filled when they are empty or missing (e.g. value for group columns)

Method Detail

exportPage

protected void exportPage(JRPrintPage page)
                   throws java.io.IOException

Specified by:

exportPage in class JRAbstractCsvExporter

Throws:

java.io.IOException

setParameters

protected void setParameters()

Overrides:

setParameters in class JRAbstractCsvExporter

setColumnNames

protected void setColumnNames()

writeReportHeader

protected void writeReportHeader()
                          throws java.io.IOException

Writes the delimiter-separated column names

Throws:

java.io.IOException

writeCurrentRow

protected void writeCurrentRow(java.util.Map<java.lang.String,java.lang.String> currentRow,
                   java.util.Map<java.lang.String,java.lang.String> repeatedValues)
                        throws java.io.IOException

Writes the current row.

If the row is empty, nothing is written. If the are columns for auto fill (with valid data), they will be set on the current row and the row will be written only if it was not originally empty. This prevents the export file from having rows just with auto filled data.

Parameters:

currentRow -

repeatedValues -

Throws:

java.io.IOException
