  1. POHow can I store a reference to a set of static Java methods from Scala?
    text
    copied!<p>In the context of Eclipse Databinding, there are quite a few Java classes that act as factories for <code>IObservable</code> objects. For instance, there's <code>BeanObservables</code>, <code>PojoObservables</code>, <code>EMFObservables</code>, etc., and they all implement a set of methods similar to</p> <pre><code> public static IObservableValue observeValue(Object target, String property) </code></pre> <p>Now if we were in the Scala world, each of those factories would probably be a singleton object implementing a common trait, say, <code>IObservableFactory</code>, and I could, for instance, pass them around as implicit values to methods that would use them to create data bindings.</p> <p>But as they are defined in Java, it seems I can do none of that. I can't write</p> <pre><code>val pojoObservableFact = PojoObservables </code></pre> <p>because <code>PojoObservables</code> is not recognized as being a value.</p> <p>Is there any way to make the compiler "instantiate" a singleton that would correspond to the <code>PojoObservables</code> class in Scala? Or any workaround for it? I know I could write the singleton myself and forward all method calls, but this sounds a bit tedious.</p> <hr> <p><strong>Edit</strong></p> <p>To make it clearer: this is what I'm trying to do: define a method that creates the observable value using a passed factory.</p> <pre><code>def createObservable(fact: ObservableFactory, target: AnyRef, property: String) = fact.observeValue(target, property) </code></pre> <p>but I wouldn't know how to define <code>ObservableFactory</code> or how to actually pass <code>PojoObservables</code>, a Java class with only static methods, to this <code>createObservable</code> method. </p>
