public abstract class AbstractObjectListProcessor<T extends Context> extends AbstractObjectProcessor<T>
Processor implementation for storing all rows parsed and converted to Object arrays into a list.
A typical use case of this class will be:
ObjectRowListProcessor processor = new ObjectRowListProcessor(); processor.convertIndexes(Conversions.toBigDecimal()).set(4, 6); parserSettings.setRowProcessor(new ObjectRowListProcessor()); parser.parse(reader); // will invoke the {@link AbstractObjectListProcessor#rowProcessed(Object[], T)} method for each parsed record. String[] headers = rowProcessor.getHeaders(); List<Object[]> rows = rowProcessor.getRows(); BigDecimal value1 = (BigDecimal) row.get(4); BigDecimal value2 = (BigDecimal) row.get(6);

void |
processEnded(T context)
This method will by invoked by the parser once, after the parsing process stopped and all resources were closed.
|
void |
processStarted(T context)
This method will by invoked by the parser once, when it is ready to start processing the input.
|

rowProcessed(Object[] row,
T context)
Stores the row extracted by the parser and them converted to an Object array into a list.
