B4J Question write map with order preservations (or sort on read)

[sorex]

Hello,

I wanted to write some data to a file so I went for the write map option.

When I look at the file content I see that the data is written random order.

As the map object doesn't seem to have a sort on key/value option I wonder how I can store data in a specific fixed order or sort them with ease on reading them?

Do I really need to go for xml, json, csv instead of this usefull single line core command?

Use RandomAccessFile.WriteB4XObject. It will preserve the order.

thanks, Erel.

That's a binary format, is it some kind of compressed csv?

No. It is a binary serialization (cross platform with B4A and B4i).
