Class used to register all desired DOperables and DOperations.
Represents knowledge about the set of possible types.
Represents method of DOperable.
Objects of classes with this trait can be used in two ways.
Objects of classes with this trait can be used in two ways. 1. It can be object on which you can perform DOperations. 2. It can be used to infer knowledge about objects that will be used later in workflow, before it's execution. DOperable that can be used for execution can ALWAYS be used for inference, but not vice-versa.
