KTBS built-in method implementations¶

Implementation of the built-in methods shipped with kTBS.

Interface¶

I define the interface of a method implementation.

class ktbs.methods.interface.IMethod[source]¶

I define the interface of a method implementation.

compute_trace_description(computed_trace)[source]¶

I set the computed properties (model, origin) of the given trace

Parameters:	computed_trace – a `engine.trace.ComputedTrace`
Return type:	`rdfrest.util.Diagnosis`

The returned diagnosis must be non-empty if the model and/or the origin could not be set, or if it is predicatable that compute_obsels will fail. It can be non-empty in other situations, but the message should then make it clear that it is a mere warning (rather than an error).

Note also that after this method is called, compute_obsels() is expected to start afresh.

compute_obsels(computed_trace, from_scratch=False)[source]¶

I update the obsels of the given computed trace

Parameters:	computed_trace – a `engine.trace.ComputedTrace` from_scratch – force a complete recalculation, regardless of the state of the sources
Return type:	`rdfrest.util.Diagnosis`
