  com.univocity.parsers.common.DefaultConversionProcessor
      com.univocity.parsers.common.processor.core.AbstractBeanConversionProcessor<T>
          com.univocity.parsers.common.processor.BeanWriterProcessor<T>

Type Parameters:

T - the annotated class type.

All Implemented Interfaces:

ConversionProcessor, RowWriterProcessor<T>

public class BeanWriterProcessor<T>
extends AbstractBeanConversionProcessor<T>
implements RowWriterProcessor<T>

A RowWriterProcessor implementation for converting annotated java objects into object arrays suitable for writing in any implementation of AbstractWriter.

The class type of the object must contain the annotations provided in com.univocity.parsers.annotations.

For any given java bean instance, this processor will read and convert annotated fields into an object array.
