[Gdal-dev] In memory OGR layers?

[Simon Perkins]

Is there an OGR format that I can use to create a vector layer in 
memory? Similar to the MEM driver for GDAL, but for vector layers?

In my application I have a need to create a vector layer and I don't 
want it to be backed up with a file unless the user subsequently decides 
to save it as one. However, I want my same vector layer rendering 
machinery to be able to handle regular OGR layers as well, so it would 
be convenient if I could create an internal memory layer and access it 
via OGR.

Any suggestions?

Cheers,

Simon
