FileASTRequestor.acceptAST is called for each of the
compilation units passed to
After all the compilation units have been processed,
FileASTRequestor.acceptBinding is called for each
of the binding keys passed to
This class is intended to be subclassed by clients. AST requestors are serially reusable, but neither reentrant nor thread-safe.

Caveat: During an
acceptASTcallback, there are implementation limitations concerning the look up of binding keys representing local elements. In some cases, the binding is unavailable, and
nullwill be returned. This is only an issue during an
acceptASTcallback, and only when the binding key represents a local element (e.g., local variable, local class, method declared in anonymous class). There is no such limitation outside of
acceptASTcallbacks, or for top-level types and their members even within
