HarmonyOS attributeModifier是否支持继承？

class MyButtonModifier implements AttributeModifier<ButtonAttribute> {  
  isDark: boolean = false  
  applyNormalAttribute(instance: ButtonAttribute): void {  
    if (this.isDark) {  
      instance.backgroundColor(Color.Black)  
    } else {  
      instance.backgroundColor(Color.Red)  
    }  
  }  
}  
  
class MyButtonModifierOM extends MyButtonModifier{  
  
}  
  
@Entry  
@Component  
struct attributeDemo {  
  @State modifierom: MyButtonModifier = new MyButtonModifierOM()  
  build() {  
    Row() {  
      Column() {  
        Button("Button")  
          .attributeModifier(this.modifierom)  
      }  
      .width('100%')  
    }  
    .height('100%')  
  }  
}
