I have a line layer with lines potentially having multiple vertices (aside from start and end point) and I need the concerned features to be split at the vertex.
explodelines algorithm does this but it creates a new layer. I need imperatively to edit my input layer as opposed to create a new one. I can't also create a new .shp layer and work with that one instead since I need to run a bunch of operations on it.
So far I've found these two threads Building a QGIS 3.10 script without an output layer and Modify the input layer when using processing algorithms from the console but I can't find a solution in neither.
If there's somehow a way to directly edit input layer directly using processing algorithms that would be the best case scenario as a lot of operations are covered by readily available algorithms already.
