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> |

2054 | Useful when another matcher requires a child matcher, but there's no |

2056 | to an internal::Matcher<> type such as TypeMatcher. |
2057 | |
2058 | Example: DeclarationMatcher(anything()) matches all declarations, e.g., |
2059 | "int* p" and "void f()" in |
2060 | int* p; |

7070 | this resolves one layer of indirection. For example, in the value |
7071 | declaration "X x;", cxxRecordDecl(hasName("X")) matches the declaration of |
7072 | X, while varDecl(hasType(cxxRecordDecl(hasName("X")))) matches the |
7073 | declaration of x. |
7074 | |
7075 | Example matches x (matcher = expr(hasType(cxxRecordDecl(hasName("X"))))) |
7076 | and z (matcher = varDecl(hasType(cxxRecordDecl(hasName("X"))))) |
