  - 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 but in this case would be useful.
