85 /// A class that does preorder or postorder
86 /// depth-first traversal on the entire Clang AST and visits each node.
87 ///
88 /// This class performs three distinct tasks:
89 /// 1. traverse the AST (i.e. go to each node);
90 /// 2. at a given node, walk up the class hierarchy, starting from
91 /// the node's dynamic type, until the top-most class (e.g. Stmt,
92 /// Decl, or Type) is reached.
93 /// 3. given a (node, class) combination, where 'class' is some base
94 /// class of the dynamic type of 'node', call a user-overridable
95 /// function to actually visit the node.
96 ///
97 /// These tasks are done by three groups of methods, respectively:
98 /// 1. TraverseDecl(Decl *x) does task #1. It is the entry point
99 /// for traversing an AST rooted at x. This method simply
100 /// dispatches (i.e. forwards) to TraverseFoo(Foo *x) where Foo
101 /// is the dynamic type of *x, which calls WalkUpFromFoo(x) and
102 /// then recursively visits the child nodes of x.
103 /// TraverseStmt(Stmt *x) and TraverseType(QualType x) work
104 /// similarly.
105 /// 2. WalkUpFromFoo(Foo *x) does task #2. It does not try to visit
106 /// any child node of x. Instead, it first calls WalkUpFromBar(x)
107 /// where Bar is the direct parent class of Foo (unless Foo has
108 /// no parent), and then calls VisitFoo(x) (see the next list item).
109 /// 3. VisitFoo(Foo *x) does task #3.
110 ///
111 /// These three method groups are tiered (Traverse* > WalkUpFrom* >
112 /// Visit*). A method (e.g. Traverse*) may call methods from the same
113 /// tier (e.g. other Traverse*) or one tier lower (e.g. WalkUpFrom*).
114 /// It may not call methods from a higher tier.
115 ///
116 /// Note that since WalkUpFromFoo() calls WalkUpFromBar() (where Bar
117 /// is Foo's super class) before calling VisitFoo(), the result is
118 /// that the Visit*() methods for a given node are called in the
119 /// top-down order (e.g. for a node of type NamespaceDecl, the order will
120 /// be VisitDecl(), VisitNamedDecl(), and then VisitNamespaceDecl()).
121 ///
122 /// This scheme guarantees that all Visit*() calls for the same AST
123 /// node are grouped together. In other words, Visit*() methods for
124 /// different nodes are never interleaved.
125 ///
126 /// Clients of this visitor should subclass the visitor (providing
127 /// themselves as the template argument, using the curiously recurring
128 /// template pattern) and override any of the Traverse*, WalkUpFrom*,
129 /// and Visit* methods for declarations, types, statements,
130 /// expressions, or other AST nodes where the visitor should customize
131 /// behavior. Most users only need to override Visit*. Advanced
132 /// users may override Traverse* and WalkUpFrom* to implement custom
133 /// traversal strategies. Returning false from one of these overridden
134 /// functions will abort the entire traversal.
135 ///
136 /// By default, this visitor tries to visit every part of the explicit
137 /// source code exactly once. The default policy towards templates
138 /// is to descend into the 'pattern' class or function body, not any
139 /// explicit or implicit instantiations. Explicit specializations
140 /// are still visited, and the patterns of partial specializations
141 /// are visited separately. This behavior can be changed by
142 /// overriding shouldVisitTemplateInstantiations() in the derived class
143 /// to return true, in which case all known implicit and explicit
144 /// instantiations will be visited at the same time as the pattern
145 /// from which they were produced.
146 ///
147 /// By default, this visitor preorder traverses the AST. If postorder traversal
148 /// is needed, the \c shouldTraversePostOrder method needs to be overridden
149 /// to return \c true.
