Getting information about current workflow within a NodeModel

KNIME Development
#1

Is there a possibility to get some workflow-specific information when executing a NodeModel? I need to cache some data which cannot be serialized and passed through the ports, and I would like to make sure, that this data is cleanly separated between different workflows.

So, basically all I need is some way to distinguish, if my node is executed in workflow A, B, or, … by a name, identifier, etc.

Best,
Philipp

Just discovered NodeContext.getContext().getWorkflowManager().getName() … if that should be the totally wrong way, I would be greatful for a hint :)

Just to add here: you can also look into the implementation of the "Extract Context Properties" node. It outputs different context parameters as variables.
