Reports non-static inner classes that implement <code>java.io.Serializable</code>, but do not define a <code>serialVersionUID</code> field.
|
|
<p>
|
|
Without a <code>serialVersionUID</code> field, any change to the class will make previously
|
|
serialized versions unreadable. It is strongly recommended that <code>Serializable</code>
|
|
non-static inner classes have a <code>serialVersionUID</code> field, otherwise the default
|
|
serialization algorithm may result in serialized versions being incompatible between
|
|
compilers due to differences in synthetic accessor methods.
|
|
</p>
|
|
<p>
|
|
A quick-fix is suggested to add the missing <code>serialVersionUID</code> field.
|
|
</p>
|
|
<p><b>Example:</b></p>
|
|
<pre><code>
|
|
class Outer {
|
|
class Inner implements Serializable {}
|
|
}
|
|
</code></pre>
|
|
<p>After the quick-fix is applied:</p>
|
|
<pre><code>
|
|
class Outer {
|
|
class Inner implements Serializable {
|
|
private static final long serialVersionUID = -7004458730436243902L;
|
|
}
|
|
}
|
|
</code></pre>

<p>Use the following options to configure the inspection:</p>
|
|
<ul>
|
|
<li>
|
|
List classes whose inheritors should not be reported by this inspection.
|
|
This is meant for classes that inherit
|
|
<code>Serializable</code> from a superclass but are not intended for serialization.
|
|
</li>
|
|
<li>
|
|
Whether to ignore <code>Serializable</code> anonymous classes.
