Constructor Summary
public  RETERuleInfGraph(Reasoner reasoner, Graph schema)
     Constructor.
public  RETERuleInfGraph(Reasoner reasoner, List rules, Graph schema)
     Constructor.
public  RETERuleInfGraph(Reasoner reasoner, List rules, Graph schema, Graph data)
     Constructor.

Method Summary
protected  voidinstantiateRuleEngine(List rules)
     Instantiate the forward rule engine to use.
public synchronized  voidperformAdd(Triple t)
     Add one triple to the data graph, run any rules triggered by the new data item, recursively adding any generated triples.
public  voidperformDelete(Triple t)
     Removes the triple t (if possible) from the set belonging to this graph.


Constructor Detail
RETERuleInfGraph
public RETERuleInfGraph(Reasoner reasoner, Graph schema)(Code)
Constructor. Creates a new inference graph to which a (compiled) rule set and a data graph can be attached. This separation of binding is useful to allow any configuration parameters (such as logging) to be set before the data is added. Note that until the data is added using RETERuleInfGraph.rebind rebind then any operations like add, remove, find will result in errors.
Parameters:
  reasoner - the parent reasoner
Parameters:
  schema - the (optional) schema data which is being processed



RETERuleInfGraph
public RETERuleInfGraph(Reasoner reasoner, List rules, Graph schema)(Code)
Constructor. Creates a new inference graph based on the given rule set. No data graph is attached at this stage. This is to allow any configuration parameters (such as logging) to be set before the data is added. Note that until the data is added using RETERuleInfGraph.rebind rebind then any operations like add, remove, find will result in errors.
Parameters:
  reasoner - the parent reasoner
Parameters:
  rules - the list of rules to use this time
Parameters:
  schema - the (optional) schema or preload data which is being processed



RETERuleInfGraph
public RETERuleInfGraph(Reasoner reasoner, List rules, Graph schema, Graph data)(Code)
Constructor. Creates a new inference graph based on the given rule set then processes the initial data graph. No precomputed deductions are loaded.
Parameters:
  reasoner - the parent reasoner
Parameters:
  rules - the list of rules to use this time
Parameters:
  schema - the (optional) schema or preload data which is being processed
Parameters:
  data - the data graph to be processed




Method Detail
instantiateRuleEngine
protected void instantiateRuleEngine(List rules)(Code)
Instantiate the forward rule engine to use. Subclasses can override this to switch to, say, a RETE imlementation.
Parameters:
  rules - the rule set or null if there are not rules bound in yet.



performAdd
public synchronized void performAdd(Triple t)(Code)
Add one triple to the data graph, run any rules triggered by the new data item, recursively adding any generated triples.



performDelete
public void performDelete(Triple t)(Code)
Removes the triple t (if possible) from the set belonging to this graph.
