Method Detail

write

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

Executes the sequences of conversions defined using DefaultConversionProcessor.convertFields(Conversion...), DefaultConversionProcessor.convertIndexes(Conversion...) and DefaultConversionProcessor.convertAll(Conversion...), for every field in the given row.

Each field will be transformed using the Conversion.execute(Object) method.

In general the conversions will process a String and convert it to some object value (such as booleans, dates, etc).

Specified by:

write in interface RowWriterProcessor<Object[]>

Parameters:

input - the object array that represents a record with its individual fields.

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:

an row of Object instances containing the values obtained after the execution of all conversions.

Fields that do not have any conversion defined will just be copied to the object array into their original positions.
