Method Detail

write

void write(List<?> columns)
    throws IOException

Writes a List of Objects as columns of a CSV file. toString() will be called on each element prior to writing.

Parameters:

columns - the columns to write

Throws:

IllegalArgumentException - if columns.size == 0

IOException - If an I/O error occurs

NullPointerException - if columns is null

SuperCsvException - if there was a general exception while writing

Since:

1.0

write

void write(List<?> columns,
           CellProcessor[] processors)
    throws IOException

Writes a List of Objects as columns of a CSV file, performing any necessary processing beforehand. toString() will be called on each (processed) element prior to writing.

Parameters:

columns - the columns to write

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:

IllegalArgumentException - if columns.size == 0

IOException - If an I/O error occurs

NullPointerException - if columns or processors is null

SuperCsvConstraintViolationException - if a CellProcessor constraint failed

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

Since:

1.0

write

void write(Object... columns)
    throws IOException

Writes a array of Objects as columns of a CSV file. toString() will be called on each element prior to writing.

Parameters:

columns - the columns to write

Throws:

IllegalArgumentException - if columns.length == 0

IOException - If an I/O error occurs

NullPointerException - if columns is null

SuperCsvException - if there was a general exception while writing

Since:

1.0

write

void write(String... columns)
    throws IOException

Writes an array of strings as columns of a CSV file.

Parameters:

columns - the columns to write

Throws:

IllegalArgumentException - if columns.length == 0

IOException - If an I/O error occurs

NullPointerException - if columns is null

SuperCsvException - if there was a general exception while writing
