Serializable

public final class InconsistentRowLengthException
extends org.apache.metamodel.InconsistentRowFormatException

Exception thrown when a line in a CSV file has an inconsistent amount of columns compared to the previous lines (and headers). The exception will be thrown when DataSet.next() is called. Note that this exception is only thrown if the CsvConfiguration.isFailOnInconsistentRowLength() property is true. Enabling it allows a somewhat different approach to iterating through a resulting DataSet. For example something like:

 while (true) {
        try {
                if (!dataSet.next) {
                        break;
                }
                Row row = dataSet.getRow();
                handleRegularRow(row);
        } catch (InconsistentRowLengthException e) {
                handleIrregularRow(e.getSourceLine());
        }
 }
