All Implemented Interfaces:

ConversionProcessor, Processor<T>

Direct Known Subclasses:

ObjectRowListProcessor

public abstract class AbstractObjectListProcessor<T extends Context>
extends AbstractObjectProcessor<T>

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);

Method Detail

processStarted

public void processStarted(T context)

Description copied from interface: Processor

This method will by invoked by the parser once, when it is ready to start processing the input.

Specified by:

processStarted in interface Processor<T extends Context>

Overrides:

processStarted in class AbstractObjectProcessor<T extends Context>

Parameters:

context - A contextual object with information and controls over the current state of the parsing process

rowProcessed

public void rowProcessed(Object[] row,
                         T context)

Stores the row extracted by the parser and them converted to an Object array into a list.

Specified by:

rowProcessed in class AbstractObjectProcessor<T extends Context>

Parameters:

row - the data extracted by the parser for an individual record and converted to an Object array.

context - A contextual object with information and controls over the current state of the parsing process

processEnded

public void processEnded(T context)

Description copied from interface: Processor

This method will by invoked by the parser once, after the parsing process stopped and all resources were closed.

It will always be called by the parser: in case of errors, if the end of the input us reached, or if the user stopped the process manually using Context.stop().

Specified by:

processEnded in interface Processor<T extends Context>

Overrides:

processEnded in class AbstractObjectProcessor<T extends Context>

Parameters:

context - A contextual object with information and controls over the state of the parsing process

getRows

public List<Object[]> getRows()

Returns the list of parsed and converted records

Returns:

the list of parsed and converted records

getHeaders

public String[] getHeaders()

Returns the record headers. This can be either the headers defined in CommonSettings.getHeaders() or the headers parsed in the file when CommonSettings.getHeaders() equals true

Returns:

the headers of all records parsed.
