Item.getAcceptedDataTypes介绍

[英]This method provides a list of all data types that can be used to update the item state

Imagine e.g. a dimmer device: It's status could be 0%, 10%, 50%, 100%, but also OFF or ON and maybe UNDEFINED. So the accepted data types would be in this case PercentType, OnOffType and UnDefType

The order of data types denotes the order of preference. So in case a state needs to be converted in order to be accepted, it will be attempted to convert it to a type from top to bottom. Therefore the type with the least information loss should be on top of the list - in the example above the PercentType carries more information than the OnOffType, hence it is listed first.
[中]此方法提供可用于更新项目状态的所有数据类型的列表
想象一下，例如一个调光器设备：它的状态可能是0%、10%、50%、100%，但也可能是关闭或打开，并且可能是未定义的。因此，在本例中，接受的数据类型将是PercentType、OnOffType和UndeType
数据类型的顺序表示优先顺序。因此，如果一个状态需要转换才能被接受，它将尝试从上到下将其转换为一种类型。因此，信息丢失最少的类型应该位于列表的顶部-在上面的示例中，PercentType比OnOffType承载更多的信息，因此它被列在第一位。
