Method Details

shouldTrace
boolean shouldTrace()Return true if tracing should be acted on  i.e. if traceOn is true and we are past the bootstrap phase. 
addBRule
Adds a new Backward rule as a rules of a forward rule process. Only some infgraphs support this. 
deleteBRule
Deletes a new Backward rule as a rules of a forward rule process. Only some infgraphs support this. 
getDeductionsGraph
Graph getDeductionsGraph()Return the Graph containing all the static deductions available so far. Triggers a prepare if the graph has not been prepared already. Specified by:
getDeductionsGraph
in interfaceInfGraph
 Returns:
 the deductions graph, if relevant for this class of inference engine or null if not.

getCurrentDeductionsGraph
Graph getCurrentDeductionsGraph()Return the Graph containing all the static deductions available so far. Does not trigger a prepare action. 
addDeduction
Add a new deduction to the deductions graph. 
findDataMatches
Search the combination of data and deductions graphs for the given triple pattern. This may different from the normal find operation in the base of hybrid reasoners where we are sidestepping the backward deduction step. 
shouldLogDerivations
boolean shouldLogDerivations()Return true if derivation logging is enabled. 
logDerivation
Logger a derivation record against the given triple. 
setFunctorFiltering
void setFunctorFiltering(boolean param) Set to true to cause functorvalued literals to be dropped from rule output. Default is true.
