Feature of adding custom processors in existing layouting algorithms [message #1759019]

Hello,

i've implemented a new processor (ILayoutProcessor) and I'm adding it hardcoded to the existing Layered Layout Provider. For this approach i have added a line in the GraphConfigurator.prepareGraphForLayout method (algorithm.add(15, new LayerSizeProcessor())).

Is there a more convenient way of adding a processor to the algorithm list (Property InternalProperties.PROCESSORS)? Thanks in advance.

Best regards

Hi Mehmet,

no, the algorithm is not designed to be augmented from the outside because of the way dependency resolution between processors works. What exactly does your processor do? If the feature is generally useful enough, we could consider adding it to the algorithm.

Cheers,

Hello Christoph,

thanks for answering. My processor finds the average or max width of nodes in the contained layer and sets to all nodes in the current layer. At the end it looks like rasterized and aligned on the left side with the same width of all nodes in one layer. If you find it useful i could provide the source code.

Best regards

Hi Mehmet,

thanks a lot for your offer, but I think that's a bit too specific of a feature and not that easy to implement such that it works in the general case.

Cheers,
Christoph Daniel
