[Qgis-developer] Basic Processing plugin questions

[Tom Chadwin]

Hello all

I'm looking at writing a Processing plugin, but I have some incredibly basic
questions, as I've never really used Processing myself:

1. Can a Processing plugin only take a single layer as input, or can it take
more?

2. Can a Processing plugin take *any* layer, rather than having to choose
between raster and vector?

3. Must a Processing plugin output a layer?

I'm sure I'll have more, so apologies in advance.

Thanks

Tom
