addInferredStatement
public boolean addInferredStatement(Resource subj, IRI pred, Value obj, Resource... contexts) throws SailException Description copied from interface:InferencerConnectionAdds an inferred statement to a specific context.- Specified by:
addInferredStatementin interfaceInferencerConnection- Overrides:
addInferredStatementin classSailSourceConnection- Parameters:
subj- The subject of the statement to add.pred- The predicate of the statement to add.obj- The object of the statement to add.contexts- The context(s) to add the statement to. Note that this parameter is a vararg and as such is optional. If no contexts are supplied the method operates on the entire repository.- Throws:
SailException- If the statement could not be added.

removeInferredStatementin classSailSourceConnection- Parameters:
subj- The subject of the statement that should be removed.pred- The predicate of the statement that should be removed.obj- The object of the statement that should be removed.contexts- The context(s) from which to remove the statements. Note that this parameter is a vararg and as such is optional. If no contexts are supplied the method operates on the entire repository.- Throws:
SailException- If the statement could not be removed.

supportsConcurrentReads
public boolean supportsConcurrentReads()Description copied from interface:ThreadSafetyAwareA class may support concurrent reads from multiple threads against the same object. This ability may change based on an object's current state.- Specified by:
supportsConcurrentReadsin interfaceThreadSafetyAware- Returns:
- true if this object supports concurrent reads
