Constructor Details

RETERuleInfGraph

public RETERuleInfGraph(Reasoner reasoner,
 Graph schema)

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 rebind then any operations like add, remove, find will result in errors.

Parameters:

reasoner - the parent reasoner

schema - the (optional) schema data which is being processed

RETERuleInfGraph

public RETERuleInfGraph(Reasoner reasoner,
 List<Rule> rules,
 Graph schema)

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 rebind then any operations like add, remove, find will result in errors.

Parameters:

reasoner - the parent reasoner

rules - the list of rules to use this time

schema - the (optional) schema or preload data which is being processed

RETERuleInfGraph

public RETERuleInfGraph(Reasoner reasoner,
 List<Rule> rules,
 Graph schema,
 Graph data)

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

rules - the list of rules to use this time

schema - the (optional) schema or preload data which is being processed

data - the data graph to be processed

Method Details

performAdd

public void performAdd(Triple t)

Add one triple to the data graph, run any rules triggered by the new data item, recursively adding any generated triples.

Specified by:

performAdd in interface GraphWithPerform

Overrides:

performAdd in class BasicForwardRuleInfGraph

performDelete

public void performDelete(Triple t)

Removes the triple t (if possible) from the set belonging to this graph.

Specified by:

performDelete in interface GraphWithPerform

Overrides:

performDelete in class BasicForwardRuleInfGraph
