run

run(action: IActionExtractLinks): Promise<IActorExtractLinksOutput>
Run the given action on this actor.

In most cases, this method should not be called directly. Instead, #runObservable should be called.
Parameters
- action: IActionExtractLinks
  The action to run.
Returns Promise<IActorExtractLinksOutput>
A promise that resolves to the run result.
Overrides ActorExtractLinks.run
- Defined in packages/actor-extract-links-headers/lib/ActorExtractLinksHeaders.ts:23

runObservable

runObservable(
action: IActionExtractLinks,
sideData: undefined,
): Promise<IActorExtractLinksOutput>
Run the given action on this actor AND invokes the Bus#onRun method.
Parameters
- action: IActionExtractLinks
  The action to run.
- sideData: undefined
Returns Promise<IActorExtractLinksOutput>
A promise that resolves to the run result.
Inherited from ActorExtractLinks.runObservable
- Defined in node_modules/@comunica/core/lib/Actor.d.ts:68

test

test(_action: IActionExtractLinks): Promise<TestResult<IActorTest>>
Check if this actor can run the given action, without actually running it.
Parameters
- _action: IActionExtractLinks
  The action to test.
Returns Promise<TestResult<IActorTest>>
A promise that resolves to the test result.
Overrides ActorExtractLinks.test

): Promise<ILink[]>
A helper function to append links based on incoming quads.
Parameters
- metadata: Stream
  A metadata stream of quads.
- onQuad: (quad: Quad, links: ILink[]) => void
  A callback that will be invoked for each quad in the metadata stream. The second argument is the array of links that can be appended to.
Returns Promise<ILink[]>
