CsvListWriter

public CsvListWriter(java.io.Writer writer,
                     CsvPreference preference)

Constructs a new CsvListWriter with the supplied Writer and CSV preferences. Note that the reader will be wrapped in a BufferedReader before accessed.

Parameters:

writer - the writer

Throws:

java.lang.NullPointerException - if writer or preference are null

Method Detail

write

public 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.

Specified by:

write in interface ICsvListWriter

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:

java.io.IOException - If an I/O error occurs

write

public 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.

Specified by:

write in interface ICsvListWriter

Parameters:

columns - the columns to write

Throws:

java.io.IOException - If an I/O error occurs

write

public void write(java.lang.Object... columns)
           throws java.io.IOException

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

Specified by:

write in interface ICsvListWriter

Parameters:

columns - the columns to write

Throws:

java.io.IOException - If an I/O error occurs

write

public void write(java.lang.String... columns)
           throws java.io.IOException

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

Specified by:
