Class BeanWriterProcessor<T>

java.lang.Object

com.univocity.parsers.common.DefaultConversionProcessor

com.univocity.parsers.common.processor.core.BeanConversionProcessor<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 BeanConversionProcessor<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.

Constructor Details

BeanWriterProcessor

public BeanWriterProcessor(Class<T> beanType)

Initializes the BeanWriterProcessor with the annotated bean class

Parameters:

beanType - the class annotated with one or more of the annotations provided in com.univocity.parsers.annotations.

Method Details

write

public Object[] write(T input,
 String[] headers,
 int[] indexesToWrite)

Converts the java bean instance into a sequence of values for writing.

Parameters:

input - an instance of the type defined in this class constructor.

headers - All field names used to produce records in a given destination. May be null if no headers have been defined in CommonSettings.getHeaders()

indexesToWrite - The indexes of the headers that are actually being written. May be null if no fields have been selected using CommonSettings.selectFields(String...) or CommonSettings.selectIndexes(Integer...)

Returns:

a row of objects containing the values extracted from the java bean

write

public Object[] write(T input,
 NormalizedString[] headers,
 int[] indexesToWrite)

Converts the java bean instance into a sequence of values for writing.

Specified by:

write in interface RowWriterProcessor<T>

Parameters:

input - an instance of the type defined in this class constructor.

headers - All field names used to produce records in a given destination. May be null if no headers have been defined in CommonSettings.getHeaders()

indexesToWrite - The indexes of the headers that are actually being written. May be null if no fields have been selected using CommonSettings.selectFields(String...) or CommonSettings.selectIndexes(Integer...)

Returns:

a row of objects containing the values extracted from the java bean

cloneConversions

protected FieldConversionMapping cloneConversions()

Description copied from class: BeanConversionProcessor

Creates a copy of the manually defined conversions to be applied over any columns.

Overrides:

cloneConversions in class BeanConversionProcessor<T>

Returns:

a copy of the currently defined conversions
