Interface RepositoryClient

SPARQL repository query and update operations.

Groups the four core operations: ask, select, and construct read from the backing RDF store, and update writes to it. Repository extends this surface for standalone use; the same operations are also handed to a task as the per-call client inside execute, where they run within the enclosing transaction.

See

interface RepositoryClient {
    ask(query: string): Promise<boolean>;
    select(query: string): Promise<readonly Tuple[]>;
    construct(query: string): Promise<readonly Triple[]>;
    update(update: string): Promise<void>;
}
