How to read csv file without header using opencsv?

Question

I do know the header, but the header is parsed separately. I am using a pojo with annotations and setting it as type.

My code looks like this:

 CsvToBean<MyObject> bb = new CsvToBeanBuilder<MyObject>(reader)
                .withSeparator(SEPERATOR)
                .withIgnoreLeadingWhiteSpace(true)
                .withType(MyObject.class)
                .build();

When I iterate, I get MyObject with all null values. MyObject is the pojo with fields annotated with column names.

Is there a way to set headers in opencsv?

As I mentioned in my last comment, I ended up implementing a custom strategy to fix my issue.

public class BlahMappingStrategy extends HeaderColumnNameMappingStrategy {
List<String> headerList;

public BlahMappingStrategy(List<String> headerList) {
    this.headerList = headerList;
}

@Override
public void captureHeader(CSVReader reader) throws IOException, CsvRequiredFieldEmptyException {
    if (this.type == null) {
        throw new IllegalStateException(ResourceBundle.getBundle("opencsv", this.errorLocale).getString("type.unset"));
    } else {
        String [] header = headerList.toArray(new String[headerList.size()]);
        this.headerIndex.initializeHeaderIndex(header);
    }
}

}

That is all that was needed.
