_compiledCapabilities​

protected _compiledCapabilities: Record<string, any>

Defined in: core/lib/services/iservice.d.ts:39

Capabilities detected at compile-time from @WebdaCapability-tagged interfaces.

Populated during Service.resolve by reading the service's entry in webda.module.json. Each key is a capability name (e.g., "request-filter"), and the value is an empty object {} by default. Override getCapabilities to provide capability-specific configuration or to conditionally disable capabilities.

loadCapabilities()​

protected loadCapabilities(): void

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

Called during resolve after dependency injection. Reads the service's type name from parameters, looks it up in the application's module metadata (moddas or beans section), and populates _compiledCapabilities with an empty object for each declared capability name.

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"] } } }
// Then after resolve(), this.getCapabilities() returns:
// { "request-filter": {}, "cors-filter": {} }

setModelDefinitionHelper()​

setModelDefinitionHelper(model): void

Defined in: core/lib/stores/store.d.ts:296

Override the resolved model class for this store at runtime. Used by the abstract StoreTest harness so test fixtures can substitute a subclass with extra fields in place of the configured model. In production this is a no-op the framework never calls.

computeStores()​

static computeStores(): void

Defined in: core/lib/stores/store.d.ts:318

Compute and register repositories for all known models based on available stores.

Called from Store.init() so each store's init triggers a recompute. Cannot be cached: the FIRST store to init (typically Registry) would claim every model with its fallback repository, and subsequent stores wouldn't get a chance to claim their configured models. Re-running is idempotent — registerRepository overwrites map entries in place, and the resolution loop is deterministic per current service/model state.

Returns​

void

Inherited from​

Store.computeStores
