Reports incorrect message format patterns or incorrect indexes of placeholders
|
|
<p>The following errors are reported:</p>
|
|
<ul>
|
|
<li>Unparsed or negative index</li>
|
|
<li>Unclosed brace</li>
|
|
<li>Unpaired quote. In this case, a part of a pattern may not be used</li>
|
|
<li>Probably incorrect number of quotes</li>
|
|
<li>Incorrect lower bound of nested choice patterns</li>
|
|
<li>Incorrect indexes of placeholders. In this case, a placeholder may not be substituted or an argument may not be used</li>
|
|
</ul>
|
|
<p>Examples:</p>
|
|
<pre><code>
|
|
MessageFormat.format("{wrong}", 1); // incorrect index
|
|
MessageFormat.format("{0", 1); // Unmatched brace
|
|
MessageFormat.format("'{0}", 1); // Unpaired quote
|
|
MessageFormat.format("It''''s {0}", 1); // "It''s" will be printed, instead of "It's"
|
|
MessageFormat.format("{0}", 1, 2); // The argument with index '1' is not used in the pattern
|
|
</code></pre>
|

|
<p>
|
|
Use the <b>Custom MessageFormat methods</b> table
|
|
to specify method calls that should have their arguments checked as MessageFormat patterns.
|
|
The table contains pairs of fully qualified class name and method name regular expression
|
|
to match the containing class and name of the method calls.
|
|
Class names also match subclasses.
