**Class Summary** |

**TransitiveEngine** |
Uses two transitive graph caches to store a subclass and a subproperty
lattice and use them within a larger inference graph. |

**TransitiveGraphCache** |
Datastructure used to represent a closed transitive reflexive relation. |

**TransitiveInfGraph** |
Implementation of InfGraph used by the TransitiveReasoner. |

**TransitiveReasoner** |
A simple "reasoner" used to help with API development. |

**TransitiveReasonerFactory** |
Factory class for creating blank instances of the transitive reasoner. |

Package com.hp.hpl.jena.reasoner.transitiveReasoner Description

This package contains a reasoner which supports transitive-reflexive closure
of subPropertyOf and subClassOf relations. A single tbox can optionally be
bound, which is expected to contain schema information but can contain other
information as well. A single data graph can be bound - whch is allowed to
contain schema information in which case the work of scanning the tbox is
lost and has to be redone (because the data might define sub-properties of
subPropertOf or subClassOf which were missed in the original tbox scan).

The generated InfGraph will appear to contain the union of the data graph,
the tbox graph, the reflexive-transitive closure of any subPropertyOf and
subClassOf relations together with *direct* versions of these.

### Defects

The current implementation is flawed in its handling of multiple data
bindings - you can't actually reuse the work of tbox binding across different
data sets. This will be fixed soon.
