 <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>

 <p>Note that the categorization of matchers is a great help when you combine
 them into matcher expressions. You will usually want to form matcher expressions
 that read like english sentences by alternating between node matchers and
 narrowing or traversal matchers, like this:
 <pre>
 recordDecl(hasDescendant(
     ifStmt(hasTrueExpression(
         expr(hasDescendant(
             ifStmt()))))))
 </pre>
 </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>

 <p>It is important to remember that the arguments to node matchers are
 predicates on the same node, just with additional information about the type.
 This is often useful to make matcher expression more readable by inlining bind
 calls into redundant node matchers inside another node matcher:
 <pre>
 // This binds the CXXRecordDecl to "id", as the decl() matcher will stay on
 // the same node.
 recordDecl(decl().bind("id"), hasName("::MyClass"))
 </pre>
 </p>
