Class ObjectColumnProcessor

All Implemented Interfaces:
ConversionProcessor, ColumnReader<Object>, Processor<ParsingContext>, RowProcessor

public class ObjectColumnProcessor extends AbstractObjectColumnProcessor<ParsingContext> implements RowProcessor
A RowProcessor implementation for converting rows extracted from any implementation of AbstractParser into columns of objects.

This uses the value conversions provided by Conversion instances.

For each row processed, a sequence of conversions will be executed to generate the appropriate object. Each resulting object will then be stored in a list that contains the values of the corresponding column.

At the end of the process, the user can access the lists with values parsed for all columns using the methods AbstractObjectColumnProcessor.getColumnValuesAsList(), AbstractObjectColumnProcessor.getColumnValuesAsMapOfIndexes() and AbstractObjectColumnProcessor.getColumnValuesAsMapOfNames().

Note: Storing the values of all columns may be memory intensive. For large inputs, use a BatchedObjectColumnProcessor instead
