Reports calls to the regular expression methods (such as <code>matches()</code> or <code>split()</code>)
|
|
of <code>java.lang.String</code> using constant arguments.
|
|
<p>
|
|
Such calls may be profitably replaced with a <code>private static final Pattern</code> field
|
|
so that the regular expression does not have to be compiled each time it is used.
|
|
</p>
|
|
<p><b>Example:</b></p>
|
|
<pre><code>
|
|
text.replaceAll("abc", replacement);
|
|
</code></pre>
|
|
<p>After the quick-fix is applied:</p>
|
|
<pre><code>
|
|
private static final Pattern ABC = Pattern.compile("abc", Pattern.LITERAL);
|
|
ABC.matcher(text).replaceAll(Matcher.quoteReplacement(replacement));
|
|
</code></pre>
