Method Details

run

public void run(FBRuleInfGraph infGraph,
 Finder dataFind,
 Graph inserts)

Invoke the preprocessing hook. This will be called during the preparation time of the hybrid reasoner.

Specified by:

run in interface RulePreprocessHook

Parameters:

infGraph - the inference graph which is being prepared, the hook code can use this to addDeductions 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

public boolean needsRerun(FBRuleInfGraph infGraph,
 Triple t)

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.

Specified by:

needsRerun in interface RulePreprocessHook
