public class JRCsvMetadataExporter
extends JRAbstractCsvExporter<CsvMetadataReportConfiguration,CsvMetadataExporterConfiguration,JRCsvExporterContext>

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)

Field Detail

PROPERTY_COLUMN_NAME

public static final java.lang.String PROPERTY_COLUMN_NAME

Property specifying the name of the column that should appear in the CSV export. It must be one of the values in CsvMetadataReportConfiguration.getColumnNames(), if provided.

PROPERTY_REPEAT_VALUE

public static final java.lang.String PROPERTY_REPEAT_VALUE

Property that specifies whether the value associated with PROPERTY_COLUMN_NAME should be repeated or not when it is missing.

The property itself defaults to false.

See Also:

JRPropertiesUtil, Constant Field Values

PROPERTY_DATA

public static final java.lang.String PROPERTY_DATA

Property that specifies what value to associate with PROPERTY_COLUMN_NAME.

The property itself defaults to the text value of the report element that this property is assigned to.

Method Detail

getConfigurationInterface

protected java.lang.Class<CsvMetadataExporterConfiguration> getConfigurationInterface()

Specified by:

getConfigurationInterface in class JRAbstractExporter<CsvMetadataReportConfiguration,CsvMetadataExporterConfiguration,WriterExporterOutput,JRCsvExporterContext>

getItemConfigurationInterface

protected java.lang.Class<CsvMetadataReportConfiguration> getItemConfigurationInterface()

Specified by:

getItemConfigurationInterface in class JRAbstractExporter<CsvMetadataReportConfiguration,CsvMetadataExporterConfiguration,WriterExporterOutput,JRCsvExporterContext>

ensureOutput

protected void ensureOutput()

Specified by:

ensureOutput in class JRAbstractExporter<CsvMetadataReportConfiguration,CsvMetadataExporterConfiguration,WriterExporterOutput,JRCsvExporterContext>

exportPage

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

Specified by:

exportPage in class JRAbstractCsvExporter<CsvMetadataReportConfiguration,CsvMetadataExporterConfiguration,JRCsvExporterContext>

Throws:

java.io.IOException

initExport

protected void initExport()

Overrides:

initExport in class JRAbstractCsvExporter<CsvMetadataReportConfiguration,CsvMetadataExporterConfiguration,JRCsvExporterContext>

initReport

protected void initReport()

Overrides:

initReport in class JRAbstractCsvExporter<CsvMetadataReportConfiguration,CsvMetadataExporterConfiguration,JRCsvExporterContext>

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
