write
void write(java.util.Map<java.lang.String,?> values, java.lang.String... nameMapping) throws java.io.IOException
Writes the values of the Map as columns of a CSV file, using the supplied name mapping to map values to the appropriate columns. toString() will be called on each element prior to writing.- Parameters:
values
- the Map containing the values to writenameMapping
- an array of Strings linking the Map keys 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 occurredjava.lang.NullPointerException
- if values or nameMapping are nullSuperCsvException
- if there was a general exception while writing- Since:

- the Map containing the values to writenameMapping
- an array of Strings linking the Map keys 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:
