| esid: sec-privatefieldset |
| info: | |
| PrivateFieldSet (P, O, value ) |
| 1. Assert: P is a Private Name. |
| 2. If O is not an object, throw a TypeError exception. |
| 3. If P.[[Kind]] is "field", |
| a. Let entry be PrivateFieldFind(P, O). |
| b. If entry is empty, throw a TypeError exception. |
| c. Set entry.[[PrivateFieldValue]] to value. |
| d. Return. |
| 4. If P.[[Kind]] is "method", throw a TypeError exception. |
| 5. Else, |
| a. Assert: P.[[Kind]] is "accessor". |
| b. If O.[[PrivateFieldBrands]] does not contain P.[[Brand]], throw a TypeError exception. |
| c. If P does not have a [[Set]] field, throw a TypeError exception. |
| d. Let setter be P.[[Set]]. |
| e. Perform ? Call(setter, O, value). |
| f. Return. |
| |
| ClassElementName : PrivateIdentifier |
| 1. Let privateIdentifier be StringValue of PrivateIdentifier. |
| 2. Let privateName be NewPrivateName(privateIdentifier). |
| 3. Let scope be the running execution context's PrivateEnvironment. |
| 4. Let scopeEnvRec be scope's EnvironmentRecord. |
| 5. Perform ! scopeEnvRec.InitializeBinding(privateIdentifier, privateName). |
| 6. Return privateName. |
| |
| MakePrivateReference ( baseValue, privateIdentifier ) |
| 1. Let env be the running execution context's PrivateEnvironment. |
| 2. Let privateNameBinding be ? ResolveBinding(privateIdentifier, env). |
| 3. Let privateName be GetValue(privateNameBinding). |
| 4. Assert: privateName is a Private Name. |
| 5. Return a value of type Reference whose base value is baseValue, whose referenced name is privateName, whose strict reference flag is true. |
