MethodDefinition : get ClassElementName () { FunctionBody }
|
||
|
|
1. Let key be the result of evaluating ClassElementName.
|
||
|
|
2. ReturnIfAbrupt(key).
|
||
|
|
3. If the function code for this MethodDefinition is strict mode code, let strict be true. Otherwise let strict be false.
|
||
|
|
4. Let scope be the running execution context's LexicalEnvironment.
|
||
|
|
5. Let formalParameterList be an instance of the production FormalParameters:[empty] .
|
||
|
|
6. Let closure be FunctionCreate(Method, formalParameterList, FunctionBody, scope, strict).
|
||
|
|
7. Perform MakeMethod(closure, homeObject).
|
||
|
|
8. Perform SetFunctionName(closure, key, "get").
|
||
|
|
9. If key is a Private Name,
|
||
|
|
a. If key has a [[Kind]] field,
|
||
|
|
i. Assert: key.[[Kind]] is "accessor".
|
||
|
|
ii. Assert: key.[[Brand]] is homeObject.
|
||
|
|
iii. Assert: key does not have a [[Get]] field.
|
||
|
|
iv. Set key.[[Get]] to closure.
|
||
|
|
b. Otherwise,
|
||
|
|
i. Set key.[[Kind]] to "accessor".
|
||
|
|
ii. Set key.[[Brand]] to homeObject.
|
||
|
|
iii. Set key.[[Get]] to closure.
|
||
|
|
10. Else,
|
||
|
|
a. Let desc be the PropertyDescriptor{[[Get]]: closure, [[Enumerable]]: enumerable, [[Configurable]]: true}.
|
||
|
|
b. Perform ? DefinePropertyOrThrow(homeObject, key, desc).
