RDFSForwardRuleReasoner (Apache Jena)

java.lang.Object
- org.apache.jena.reasoner.rulesys.FBRuleReasoner
- - org.apache.jena.reasoner.rulesys.GenericRuleReasoner
  - - org.apache.jena.reasoner.rulesys.RDFSForwardRuleReasoner

All Implemented Interfaces:

Reasoner, RuleReasoner
```
public class RDFSForwardRuleReasoner
extends GenericRuleReasoner
```
A pure forward chaining implementation of the RDFS closure rules based upon the basic forward rule interpreter. The normal mixed forward/backward implementation is generally preferred but this has two possible uses. First, it is a test and demonstration of the forward chainer. Second, if you want all the RDFS entailments for an entire dataset the forward chainer will be more efficient.
