write
void write(java.util.List<?> columns) throws java.io.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:
java.lang.IllegalArgumentException
- if columns.size == 0java.io.IOException
- If an I/O error occursjava.lang.NullPointerException
- if columns is nullSuperCsvException

write
void write(java.util.List<?> columns, CellProcessor[] processors) throws java.io.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 writeprocessors
- 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.lang.IllegalArgumentException
- if columns.size == 0java.io.IOException
- If an I/O error occursjava.lang.NullPointerException
- if columns or processors is nullSuperCsvConstraintViolationException
- if a CellProcessor constraint failedSuperCsvException
- if there was a general exception while writing/processing- Since:
- 1.0

write

- If an I/O error occursjava.lang.NullPointerException
