ObjectRowListProcessor
public abstract class AbstractObjectListProcessor<T extends Context> extends AbstractObjectProcessor<T>
A convenienceProcessor
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);

Creates a new processor ofObject[]
rows with varying types.
-
AbstractObjectListProcessor
public AbstractObjectListProcessor(int expectedRowCount)

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 interfaceProcessor<T extends Context>
- Overrides:
processStarted
in classAbstractObjectProcessor<T extends Context>
- Parameters:
context
- A contextual object with information and controls over the current state of the parsing process
-
rowProcessed
public void rowProcessed(java.lang.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 classAbstractObjectProcessor<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 interfaceProcessor<T extends Context>
- Overrides:
processEnded
in classAbstractObjectProcessor<T extends Context>
- Parameters:
context
- A contextual object with information and controls over the state of the parsing process
-
getRows
public java.util.List<java.lang.Object[]> getRows()
Returns the list of parsed and converted records- Returns:
- the list of parsed and converted records
-
getHeaders
public java.lang.String[] getHeaders()
Returns the record headers. This can be either the headers defined inCommonSettings.getHeaders()
or the headers parsed in the file whenCommonSettings.getHeaders()
equals true- Returns:
- the headers of all records parsed.
