Method Summary

Modifier and Type	Method	Description
void	write(java.lang.Object source, java.lang.String... nameMapping)	Writes the fields of the object as columns of a CSV file, using the supplied name mapping to map fields to the appropriate columns.

Method Detail

write

void write(java.lang.Object source,
           java.lang.String... nameMapping)
    throws java.io.IOException

Writes the fields of the object as columns of a CSV file, using the supplied name mapping to map fields to the appropriate columns. toString() will be called on each element prior to writing.

Parameters:

source - the object (bean instance) containing the values to write

nameMapping - an array of Strings linking the fields in the bean to their corresponding CSV columns (the array length should match the number of columns). A null entry in the array indicates that the column should be ignored (the column will be empty).

Throws:

java.io.IOException - if an I/O error occurred

java.lang.NullPointerException - if source or nameMapping are null

SuperCsvException - if there was a general exception while writing

SuperCsvReflectionException - if there was an reflection exception while mapping the values from the bean

write

void write(java.lang.Object source,
           java.lang.String[] nameMapping,
           CellProcessor[] processors)
    throws java.io.IOException

Writes the fields of the object as columns of a CSV file, using the supplied name mapping to map fields to the appropriate columns. toString() will be called on each (processed) element prior to writing.

Parameters:

source - the object (bean instance) containing the values to write

nameMapping - an array of Strings linking the fields in the bean to their corresponding CSV columns (the array length should match the number of columns). A null entry in the array indicates that the column should be ignored (the column will be empty).

processors - an array of CellProcessors used to further process data before it is written (each element in the processors array corresponds with a CSV column - the number of processors should match the number of columns). A null entry indicates no further processing is required (the value returned by toString() will be written as the column value).

Throws:

java.io.IOException - if an I/O error occurred

java.lang.NullPointerException - if source, nameMapping or processors are null

SuperCsvConstraintViolationException - if a CellProcessor constraint failed

SuperCsvException - if there was a general exception while writing/processing

SuperCsvReflectionException - if there was an reflection exception while mapping the values from the bean
