Defined in: core/lib/services/service.d.ts:120

Fails silently if the application is not available (e.g., in unit tests where services are instantiated without a full application context).

Returns​

void

Example​

// If webda.module.json contains:
// { "moddas": { "MyApp/HawkService": { "capabilities": ["request-filter", "cors-filter"] } } }
