class | CallGraphNode |
The AST-based call graph.
The call graph extends itself with the given declarations by implementing the recursive AST visitor, which constructs the graph by visiting the given declarations.

Definition at line 87 of file CallGraph.h.
typedef FunctionMapTy::iterator clang::CallGraph::iterator |
Iterators through all the elements in the graph. Note, this gives non-deterministic order.
Definition at line 69 of file CallGraph.h.
typedef llvm::SetVector<CallGraphNode *>::iterator clang::CallGraph::nodes_iterator |
Iterators through all the nodes of the graph that have no parent. These are the unreachable nodes, which are either unused or are due to us failing to add a call edge due to the analysis imprecision.
