<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> |
|
|
|
<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> |
