<p>That error means that the element you passed cannot be used to forward a ref, so using any element that does allow that will work. Typically you'll wrap it in an <code>&lt;a&gt;</code> tag in this case. i.e.</p> <pre><code>&lt;Link&gt; &lt;a&gt; &lt;Image /&gt; &lt;/a&gt; &lt;/Link&gt; </code></pre>

<p>On Linux, essentially all (204015.385 out of 217006.663 ms) of the time is spent on JIT (just in time compilation) in a vain attempt to make things faster. Just turn off jit, it is rarely useful in my experience.</p> <p>On Windows, you probably have the fortune of not supporting JIT in the first place.</p>

Passing class to use instanceof in a function<p>I have a class structure:</p> <pre><code>class BonusCard{ } class AddResourceCard extends BonusCard{ } class AddGoldCard extends BonusCard{ } </code></pre> <p>Now, I also have a function in which I want to pass AddResourceCard or AddGoldCard and in someones Inventory ...
<p>I think what you are looking for is <code>card.getClass().equals(cardToRemove.getClass())</code>.</p> <p>This compares the classes of the two objects and checks whether they are the same. If you want to regard some hierarchy, you would then probably rather go for isAssignableFrom instead of equals</p>
