Properties​

_compiledCapabilities​

protected _compiledCapabilities: Record<string, any> = {}

Defined in: packages/core/src/services/iservice.ts:49

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.

isCollection()​

protected isCollection(object, property): boolean

Defined in: packages/core/src/services/binary.service.ts:1685

Whether the binary attribute is a collection (BinariesImpl or a subclass) rather than a single Binary

Models are hydrated by the compiled __hydrateBehaviors (store deserialization, load, patch), which always instantiates the behavior class, even for an unset attribute: instanceof BinariesImpl therefore covers subclasses. The relation id comparison is the fallback for objects that were never hydrated.

Parameters​

object​

CoreModelWithBinary

the target object

property​

string

the property name

Returns​

boolean

true if the attribute holds several binaries

Inherited from​

loadCapabilities()​

protected loadCapabilities(): void

Defined in: packages/core/src/services/service.ts:269

Load capabilities from webda.module.json metadata into _compiledCapabilities.

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": {} }
