 <h1>AST Matcher Reference</h1>

 <p>This document shows all currently implemented matchers. The matchers are grouped
 by category and node type they match. You can click on matcher names to show the
 matcher's source documentation.</p>

 <p>There are three different basic categories of matchers:
 <ul>
 <li><a href="#decl-matchers">Node Matchers:</a> Matchers that match a specific type of AST node.</li>
 <li><a href="#narrowing-matchers">Narrowing Matchers:</a> Matchers that match attributes on AST nodes.</li>
 <li><a href="#traversal-matchers">Traversal Matchers:</a> Matchers that allow traversal between AST nodes.</li>
 </ul>
 </p>

 <p>Within each category the matchers are ordered by node type they match on.
 Note that if a matcher can match multiple node types, it will it will appear
 multiple times. This means that by searching for Matcher&lt;Stmt&gt; you can
 find all matchers that can be used to match on Stmt nodes.</p>

 <p>The exception to that rule are matchers that can match on any node. Those
 are marked with a * and are listed in the beginning of each category.</p>

 <!-- ======================================================================= -->
 <h2 id="decl-matchers">Node Matchers</h2>
 <!-- ======================================================================= -->

 <p>Node matchers are at the core of matcher expressions - they specify the type
 of node that is expected. Every match expression starts with a node matcher,
 which can then be further refined with a narrowing or traversal matcher. All
 traversal matchers take node matchers as their arguments.</p>

 <p>For convenience, all node matchers take an arbitrary number of arguments
 and implicitly act as allOf matchers.</p>

 <p>Node matchers are the only matchers that support the bind("id") call to
 bind the matched node to the given string, to be later retrieved from the
 match callback.</p>
