[solved] Getting error iterating over a Table

in Programming Questions • 6 months ago

Hi, I have a problem using Table class. I'm relatively new to it (saw it in the awesome Jer Thorpe openpaths tutorial).

When trying to iterate over my Table, I keep getting this error: Can only iterate over an array or an instance of java.lang.Iterable

My program is quite similar to the one provided here: http://processing.org/learning/data/

Couldn't figure it out myself, googling didn't help.

Here's my code (error in the for loop, line 9):

void setup() {
size(640, 480, P3D);
background(0);
Table data = loadTable("data/openpaths_roveo.csv");
data.removeTitleRow();
for (TableRow row:data) {
println(row.getFloat("lat"));
}
exit();
}

I'm using Processing 2.0b8.

Thanks!

Here white-space is significant

for (TableRow row : data) {

I have already tried different combinations of white-space, same thing is happening.

I've found the solution here: http://processing.org/reference/loadTable_.html

Table class has a method .rows() that returns the desired iterable object. It's called getRows() in javadoc on the website, but in my version of Processing it's .rows()

So, the for loop must be:

for (TableRow row : data.rows()) {
//instructions
}
