univocity-parsers 2.9.1 · com.univocity.parsers.common.processor.core.AbstractObjectListProcessor

A convenience 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);

Modifier and Type	Field and Description
private final int	expectedRowCount
private String[]	headers
private List<Object[]>	rows

Constructor Summary

Access	Constructor and Description
public	AbstractObjectListProcessor() Creates a new processor of `Object[]` rows with varying types.
public	AbstractObjectListProcessor(int expected number of rows to be parsed from the input. Used to pre-allocate the size of the output `List` returned by `getRows()` expectedRowCount) Creates a new processor of `Object[]` rows with varying types.

Method Summary

Modifier and Type	Method and Description
public String[]	Returns: the headers of all records parsed. getHeaders() Returns the record headers.
public List<Object[]>	Returns: the list of parsed and converted records getRows() Returns the list of parsed and converted records
public void	processEnded(T A contextual object with information and controls over the state of the parsing process context) Overrides com.univocity.parsers.common.processor.core.AbstractObjectProcessor.processEnded. Implements com.univocity.parsers.common.processor.core.Processor.processEnded. This method will by invoked by the parser once, after the parsing process stopped and all resources were closed.
public void	processStarted(T A contextual object with information and controls over the current state of the parsing process context) Overrides com.univocity.parsers.common.processor.core.AbstractObjectProcessor.processStarted. Implements com.univocity.parsers.common.processor.core.Processor.processStarted. This method will by invoked by the parser once, when it is ready to start processing the input.
public void	rowProcessed(Object[] the data extracted by the parser for an individual record and converted to an Object array. row, T A contextual object with information and controls over the current state of the parsing process context) Implements abstract com.univocity.parsers.common.processor.core.AbstractObjectProcessor.rowProcessed. Stores the row extracted by the parser and them converted to an Object array into a list.
