converter logic

基本解释

The code snippet shown in Listing 7 is a test driver that exercises the xml2json converter logic.
清单 7 中的代码片段是一个用于执行 xml2json 转换器逻辑的测试驱动程序。
In this case, you would either have to write a custom validator, as well, or simply include any special validation logic in the custom converter.
在这种情况下，要么编写自定义验证器，要么在自定义转换器中添加一个特别的验证逻辑。
If you want to stay "pure" to MVVM, in general, it'd be better to build a converter, which keeps the logic completely within the presentation layer (View).
如果你还想留下来“纯”MVVM，一般来说，最好建立一个转换器，使逻辑完全在表示层（视图）。

The idea of this Vivo X1 is that BBK wants to take audio very seriously on its new flagship phone, which is why it's been given a Cirrus Logic CS4398 digital-analog converter plus a CS8422 sample-rate converter -- a combo that's seemingly popular amongst Hi-Fi connoisseurs and manufacturers.

Launched by BBK spin-off Vivo in Beijing just now, this 5.7-inch Xplay takes one step further from its smaller X1 and X1S cousins by packing one extra audio chip, the OPA2604 op amp from Texas Instruments, in order to add extra oomph to Cirrus Logic's CS4398 DAC and CS8422 stereo asynchronous sample-rate converter -- both of which are featured on the X1 series.
