PrivateFieldGet (P, O)

a. Let entry be PrivateFieldFind(P, O).
|
||
|
|
b. If entry is empty, throw a TypeError exception.
|
||
|
|
c. Return entry.[[PrivateFieldValue]].
|
||
|
|
4. Perform ? PrivateBrandCheck(O, P).
|
||
|
|
5. If P.[[Kind]] is "method",
|
||
|
|
a. Return P.[[Value]].
|
||
|

|
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.
