Version:
(Deprecated: use apg-js instead.) Pattern-matching alternative to RegExp. Replaces the regular expression syntax with ABNF. Adds APG parser features such as User Defined Terminals (hand-written pattern matchers) and access to the AST.

<h1>Method: test()</h1>
<p>
The
<kbd>test()</kbd>
method executes a search for a match in the specified string. It operates like the
<kbd>
<a href="./exec.html">exec()</a>
</kbd>
method in most regards, including modes, but operates with less overhead.
</p>
<h3>Syntax</h3>
<pre>
var exp = new ApgExp(pattern[, flags]);
var result = exp.test(str);</pre>
<h3>Parameters</h3>
<ul>
<li><kbd>str:</kbd> string/array: The string to search for a pattern match in. May be a string or array of integer
character codes.</li>
</ul>
<h3>Return</h3>
<p>
If a match is found,
<kbd>true</kbd>
is returned, otherwise
<kbd>false</kbd>
.
</p>
<h3>Example</h3>
<pre>
var pattern, str, exp, result;
pattern = 'pattern = "abc"\n';
exp = new ApgExp(pattern);
result = exp.test("---abc");
console.log("result: " + result);
result = exp.test([45, 45, 45, 97, 98, 99]);
console.log("result: " + result);
result = exp.test("xyz");
