public interface RulePreprocessHook
Implementors of this interface can be used as preprocessing passes
during intialization of (hybrid) rule systems. They are typically
used to generate additional data-dependent rules or additional
deductions (normally from comprehension axioms) which are cheaper
this way than using the generic rule engines.

Method Details
-
run
Invoke the preprocessing hook. This will be called during the preparation time of the hybrid reasoner.- Parameters:
infGraph
- the inference graph which is being prepared, the hook code can use this to add pure deductions or add additional rules (using addRuleDuringPrepare).dataFind
- the finder which packages up the raw data (both schema and data bind) and any cached transitive closures.inserts
- a temporary graph into which the hook should insert all new deductions that should be seen by the rules.
-
needsRerun
Validate a triple add to see if it should reinvoke the hook. If so then the inference will be restarted at next prepare time. Incremental re-processing is not yet supported.
