Package Exports

@comunica/mediator-number
@comunica/mediator-number/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@comunica/mediator-number) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Configure

After installing, this mediator can be instantiated as follows:

{
  "@context": [
    ...
    "https://linkedsoftwaredependencies.org/bundles/npm/@comunica/mediator-number/^4.0.0/components/context.jsonld"
  ],
  "actors": [
    ...
    {
      "@type": "SomeActor",
      "someMediator": {
        "@id": "#mediatorQueryOperation",
        "@type": "MediatorNumber",
        "field": "httpRequests",
        "type": "min",
        "ignoreErrors": true,
        "bus": { "@id": "ActorQueryOperation:_default_bus" }
      }
    }
  ]
}

Instead of MediatorNumberMin, MediatorNumberMax could also be used to resolve to the maximum value.

field: The field name to mediate over.
type: The way how the index should be selected. For choosing the minimum value: 'min'. For choosing the maximum value: 'max'.
