Hello Chuck,
I'll have a look at it too:)
Hopefully I'll be choosing which direction to go by tomorrow:)
Thanks,
Xavier

Hi,
searching the list I have found many post about excel export and
things like that. But I'm actually looking for a way to import CSV
into a WO application.
Is there anything already done to handle importing of CSV?
Like providing a NSArray of column name, an editing context and an
eo to match the value to?
If you look in GVCFoundation, there is a DelimitedStringTokenizer
(ignore the incorrect class comments that someone copied and pasted
from FixedWidthStringTokenizer) that can be used to parse out each
line of CSV. It handles quotes, embedded commas etc.
In the GVCVirutalTables framework in VirtualTable.java is a method
public void importTable(InputStream stream,
Object sender,
NSArray columnsToImport,
NSDictionary formatters,
String delimiter,
boolean skipFirstLine,
boolean shouldReplace)
that is close to what you want. It is intended to work with our
Virtual Tables, not regular EOs, but would be a good starting
point. You will see that we create the objects by getting EOF to
create raw SQL Insert statements. If you are importing a lot of
data this is needed for speed. EOF is not optimized for bulk inserts.
You can get these frameworks (source and binary) here:
