| 38 | <h1>AST Matcher Reference</h1>
|
| 39 |
|
| 40 | <p>This document shows all currently implemented matchers. The matchers are grouped
|
| 41 | by category and node type they match. You can click on matcher names to show the
|
| 42 | matcher's source documentation.</p>
|
| 43 |
|
| 44 | <p>There are three different basic categories of matchers:
|
| 45 | <ul>
|
| 46 | <li><a href="#decl-matchers">Node Matchers:</a> Matchers that match a specific type of AST node.</li>
|
| 47 | <li><a href="#narrowing-matchers">Narrowing Matchers:</a> Matchers that match attributes on AST nodes.</li>
|
| 48 | <li><a href="#traversal-matchers">Traversal Matchers:</a> Matchers that allow traversal between AST nodes.</li>
|
| 49 | </ul>
|
| 50 | </p>
|
| 51 |
|
| 52 | <p>Within each category the matchers are ordered by node type they match on.
|
| 53 | Note that if a matcher can match multiple node types, it will it will appear
|
| 54 | multiple times. This means that by searching for Matcher<Stmt> you can
|
| 55 | find all matchers that can be used to match on Stmt nodes.</p>
|
| 56 |
|
| 57 | <p>The exception to that rule are matchers that can match on any node. Those
|
| 58 | are marked with a * and are listed in the beginning of each category.</p>
|
| 59 |
|
| 60 | <p>Note that the categorization of matchers is a great help when you combine
|
| 61 | them into matcher expressions. You will usually want to form matcher expressions
|
| 62 | that read like english sentences by alternating between node matchers and
|
| 63 | narrowing or traversal matchers, like this:
|
| 64 | <pre>
|
| 65 | recordDecl(hasDescendant(
|
| 66 | ifStmt(hasTrueExpression(
|
| 67 | expr(hasDescendant(
|
| 68 | ifStmt()))))))
|
| 69 | </pre>
|
| 70 | </p>
|
| 71 |
|
| 72 | <!-- ======================================================================= -->
|
| 73 | <h2 id="decl-matchers">Node Matchers</h2>
|
| 74 | <!-- ======================================================================= -->
|
| 75 |
|
| 76 | <p>Node matchers are at the core of matcher expressions - they specify the type
|
| 77 | of node that is expected. Every match expression starts with a node matcher,
|
| 78 | which can then be further refined with a narrowing or traversal matcher. All
|
| 79 | traversal matchers take node matchers as their arguments.</p>
|
| 80 |
|
| 81 | <p>For convenience, all node matchers take an arbitrary number of arguments
|
| 82 | and implicitly act as allOf matchers.</p>
|
| 83 |
|
| 84 | <p>Node matchers are the only matchers that support the bind("id") call to
|
| 85 | bind the matched node to the given string, to be later retrieved from the
|
| 86 | match callback.</p>
|
| 87 |
|
| 88 | <p>It is important to remember that the arguments to node matchers are
|
| 89 | predicates on the same node, just with additional information about the type.
|
| 90 | This is often useful to make matcher expression more readable by inlining bind
|
| 91 | calls into redundant node matchers inside another node matcher:
|
| 92 | <pre>
|
| 93 | // This binds the CXXRecordDecl to "id", as the decl() matcher will stay on
|
| 94 | // the same node.
|
| 95 | recordDecl(decl().bind("id"), hasName("::MyClass"))
|
| 96 | </pre>
|
| 97 | </p>
