value

Returns an identifier for an Assisted parameter.

Within an Inject constructor, each Assisted parameter must be uniquely defined by the combination of its identifier and type. If no identifier is specified, the default identifier is the parameter name. Thus, the following parameters have identifier "foo" within an Inject constructor:

• @Assisted foo: Foo

• @Assisted("foo") foo: Foo

Within an AssistedFactory method, each parameter must match an Assisted parameter in the associated Inject constructor (i.e. identifier + type). A parameter with no @Assisted annotation will be assigned the parameter name as its identifier. Thus, the following parameters are equivalent within an AssistedFactory method:

• foo: Foo

• @Assisted foo: Foo

• @Assisted("foo") foo: Foo

Because the parameter name is used as the default identifier, parameter names must match between the factory method and the constructor. Explicit identifiers via value are soft-deprecated and will be removed in a future release. Use matching parameter names instead.

Example:

class DataService(
  bindingFromDagger: BindingFromDagger,
  @Assisted name: String,
  @Assisted id: String,
  @Assisted repo: String,
)

@AssistedFactory
fun interface DataServiceFactory {
  fun create(
    name: String,
    id: String,
    repo: String,
  ): DataService
}
