Class AbstractRuleFastClosure_3_5_6_7_9

java.lang.Object

com.bigdata.relation.rule.Rule

com.bigdata.rdf.rules.AbstractRuleFastClosure_3_5_6_7_9

All Implemented Interfaces:

IRule, IStep, Serializable

Direct Known Subclasses:

AbstractRuleFastClosure_5_6_7_9, RuleFastClosure3

public abstract class AbstractRuleFastClosure_3_5_6_7_9
extends Rule

Rule used in steps 3, 5, 6, 7, and 9 of the fast forward closure program.

    (?x, {P}, ?y) -> (?x, propertyId, ?y)
 

where {P} is the closure of the subproperties of one of the FIVE (5) reserved keywords:

• rdfs:subPropertyOf
• rdfs:subClassOf
• rdfs:domain
• rdfs:range
• rdf:type

The caller MUST define an IRuleTaskFactory that provides a concrete implementation of AbstractRuleFastClosure_3_5_6_7_9.FastClosureRuleTask which knows how to compute "{P}" when they instantiate this rule.
