Reports redundant calls to unmodifiable collection wrappers within the
Reports redundant calls to unmodifiable collection wrappers from the
<code>Collections</code> class.
<p>If the argument that is passed to an unmodifiable
collection wrapper is already immutable, such a wrapping becomes redundant.</p>
<p>Example:</p>
<pre><code>
Collections.unmodifiableList(Collections.singletonList("abc"));
List&lt;String&gt; x = Collections.unmodifiableList(Collections.singletonList("abc"));
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
List&lt;String&gt; x = Collections.singletonList("abc");
</code></pre>
<p>In order to detect the methods that return unmodifiable collections, the
inspection uses the <code>org.jetbrains.annotations.Unmodifiable</code>
