setValue method

@override dynamic setValue(dynamic value)

设置对象的原生数据值 或 逻辑处理值

Implementation

@override
dynamic setValue(value) {
  switch (metaType) {
    case VmMetaType.externalValue:
      return _valueData = VmObject.readValue(value, type: _valueType.identifier); //保存原生值
    case VmMetaType.externalSmart:
      //与VmValue.forVariable的处理流程是一致的
      final realLogic = VmObject.readLogic(value);
      if (realLogic is VmValue) {
        _valueType = realLogic._valueType;
        return _valueData = realLogic;
      } else {
        final realClass = VmObject.readClass(value);
        final realValue = VmObject.readValue(value);
        _valueType = realClass;
        return _valueData = realValue;
      }
    case VmMetaType.externalSuper:
      final targeLayzer = _valueData() as VmLazyer;
      return targeLayzer.setValue(VmObject.readValue(value)); //保存超类值
    case VmMetaType.internalValue:
      return _valueData = VmObject.readValue(value, type: _valueType.identifier); //保存VmSuper值
    // throw ('Unsuppport setValue operator for internalValue: $identifier'); //非方法没有影响，允许修改
    case VmMetaType.internalApply:
      if (metaData.isSetter) return runFunction([value], null);
      throw ('Unsuppport setValue operator for internalApply: $identifier'); //必涉及到作用域，禁止修改
    case VmMetaType.internalAlias:
      return _valueData = VmObject.readLogic(value, type: _valueType.identifier); //保存逻辑值
  }
