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