creating a flatfile from domain model

[oliver.maske]

Hello,

I have got a complex domain model. I want to construct a CSV file from this domain model. I realized, that I can use ItemReaderAdapter to access this domain model.

My CVS file is more complicated than usual. Here is an example:

HEADCOLUMN1,HEADCOLUMN2,HEADCOLUMN3
HEADVALUE1,HEADVALUE2,HEADVALUE2
DATACOLUMN1,DATACOLUMN2,DATACOLUMN3,DATACOLUMN4
DATA1,DATA2,DATA3,DATA4
DATAA1,DATAA2,DATAA3,DATAA4

and so on.

The Head contains a headline, followed by one record.
The Data contains a headline, followed by several records.

How can I archive to write the headlines to the FlatFile before I write the domain data.

The Data in the Head is calculated from the Data.

I hope I expressed it clear enough.

Bye!

Does the file contain just one Head? If so, you can write all of your Data to a file, calculating the Head information as you go. Then in a next step, you can write a Head file and concatenate the two files together.
