BeanVerifier instead.@Deprecated public interface CsvToBeanFilter
Using a filter means you are looking at the data from the input after it has been parsed, but before a bean has been created and populated.
Filters must be thread-safe.
Here's an example showing how to use CsvToBean with a column
name mapping and line filtering. It assumes that there is a class named
Feature defined with setters setName(String) and
setState(String). The FEATURE_NAME and STATE columns in the
CSV file will be used. Any additional columns will be ignored. The filter
will eliminate any lines where the STATE value is "production".
private class StateFilter implements CsvToBeanFilter {
private final MappingStrategy strategy;
public StateFilter(MappingStrategy strategy) {
this.strategy = strategy;
}
public boolean allowLine(String[] line) {
String value = line[1];
boolean result = !"production".equals(value);
return result;
}
}
public List<Feature> parseCsv(InputStreamReader streamReader) {
HeaderColumnNameTranslateMappingStrategy<Feature> strategy = new HeaderColumnNameTranslateMappingStrategy();
Map<String, String> columnMap = new HashMap();
columnMap.put("FEATURE_NAME", "name");
columnMap.put("STATE", "state");
strategy.setColumnMapping(columnMap);
strategy.setType(Feature.class);
CSVReader reader = new CSVReader(streamReader);
CsvToBeanFilter filter = new StateFilter(strategy);
return new CsvToBean().parse(strategy, reader, filter);
}
