从Java代码访问模块定义的属性 [英] Accessing a module-defined property from Java code

问题描述

在扩展更早的答案时，我意识到我不知道是否可以访问模块定义的属性来自Java代码。例如，如果我有：

 < define-property name =formfactorvalues =desktop，tablet，mobile /> 
  

SDK中的某些内容可以像这样吗？

  String ff = [someClass] .getProperty（formfactor）`？ 
  

解决方案

您必须使用延迟绑定。

最简单的方法是使用< replace-with> 规则，但它需要相当多的样板代码每个值的类都返回与来自getter的属性相同的值）

或者您可以使用生成器并使用< generate-with> ; 规则。

在任何情况下，您都需要在代码中使用接口或基类，编码或生成）将使用延迟绑定规则进行切换。

When expanding an earlier answer I realized I don't know if it is possible to access a module-defined property from Java code. For example, if I have:

<define-property name="formfactor" values="desktop,tablet,mobile" />

Is something available in the SDK to go like this?

String ff = [someClass].getProperty("formfactor")`?

解决方案

You have to use deferred-binding.

The easiest way is to use <replace-with> rules, but it requires quite a lot of boilerplate code (one per value, with classes that return the same value as the property from a getter)

Or you could use a generator and <generate-with> rule.

In any case, you'll need an interface or base class to use in your code and whose exact implementation (either hand-coded or generated) will be switched using deferred binding rules.
