Henri Yandell commented on SANDBOX-209:
---------------------------------------
So the API has:
public void println(String value) {
public void println() {
public void println(String[] values) {
public void println(String[][] values) {
public void printlnComment(String comment) {
public void print(String value) {
Question being; what should the null functionality be in each case. If you look
at either System.out.println or StringWriter, it is to turn 'null' into "null".
In the array cases, I guess it would be { "null" } and {{ "null" }}. Very lame.
So the other obvious solution would be to implement empty functionality. That
still leaves an open question of whether that means nothing happens, or it's
akin to an empty string. ie) in the println(null) case, would you expect a
newline to be printed.
I'm thinking that can be up to the CSVStrategy.ignoreEmptyLines - if it's true,
then null means nothing. If false then null means an empty string. Or is that
bad because it's reusing a configuration option for something that is not
necessarily symmetrical with the usage in the parser :)
