Method Detail

initTokenizer

protected void initTokenizer(Reader r)

Configures the tokenizer to read the CSV stream. Important settings include whitespaceChars, which denotes "," as a whitespace character. This is important because StreamTokenizer uses whitespace as a token delimiter. Also important is the eolIsSignificant() setting of true. This returns EOL as a token that we can use to identify a new row of data.

Parameters:

r -

readAndParse

public int readAndParse(Reader r,
                        Vector vv)
                 throws IOException

This method reads the stream provided by r and puts the parsed contents into the Vector vv.

Parameters:

r - an input reader

vv - a Vector instance; if this is null, no parsing will occur

Returns:

Throws:

IOException
