<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<Stmt> 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>
