public interface RulePreprocessHook
Implementors of this interface can be used as proprocessing 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 Summary | |
|---|---|
boolean |
needsRerun(FBRuleInfGraph infGraph,
Triple t)
Validate a triple add to see if it should reinvoke the hook. |
void |
run(FBRuleInfGraph infGraph,
Finder dataFind,
Graph inserts)
Invoke the preprocessing hook. |
| Method Detail |
|---|
void run(FBRuleInfGraph infGraph,
Finder dataFind,
Graph inserts)
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.
