Description copied from interface: RepoConnection

Checks whether the specified statement is inferred by the repository.

Note that given the nature of the RDF4J API, this method will return false even if the statement is both asserted and inferred, as there is no way to easily ask only for inferred statements but both asserted and inferred statements are returned.

Also note that if the repository does not contain the statement at all, false is returned.

Specified by:

isInferred in interface RepoConnection

Overrides:

isInferred in class StorageConnection

Parameters:

statement - Statement whose inference to check

contexts - Optionally specify contexts in which the search should be performed. If empty, the default one is used

Returns:

true iff the specified statement is inferred in any of the specified contexts

Throws:

Rdf4jDriverException - If a repository access error occurs
