clone

public CsvParser clone()

Specified by:

clone in class CustomParser

parallelParseSupported

public boolean parallelParseSupported()

Overrides:

parallelParseSupported in class CustomParser

parallelParse

public final CustomParser.DataOut parallelParse(int cidx,
                                                CustomParser.DataIn din,
                                                CustomParser.DataOut dout)

Overrides:

parallelParse in class CustomParser

guessSetup

public static CustomParser.PSetupGuess guessSetup(byte[] bits)

Determines the CSV parser setup from the first two lines. Also parses the next few lines, tossing out comments and blank lines. A separator is given or it is selected if both two lines have the same ammount of them and the tokenization then returns same number of columns.
