InitializeInstanceFields ( O, constructor )
|
|
1. Assert: Type ( O ) is Object.
|
|
2. Assert: constructor is an ECMAScript function object.
|
|
3. Let fields be the value of constructor.[[Fields]].
|
|
4. For each item fieldRecord in order from fields,
|
|
a. Perform ? DefineField(O, fieldRecord).
|
|
5. Return.
|
|
|
|
DefineField(receiver, fieldRecord)
|
|
1. Assert: Type(receiver) is Object.
|
|
2. Assert: fieldRecord is a Record as created by ClassFieldDefinitionEvaluation.
|
|
3. Let name be fieldRecord.[[Name]].
|
|
4. Let initializer be fieldRecord.[[Initializer]].
|
|
5. If initializer is not empty, then
|
|
a. Let initValue be ? Call(initializer, receiver).
