| * Internal class for resolving bindings using old ASTs. |
| * <p> |
| * IMPORTANT: The methods on this class are synchronized. This is required |
| * because there may be multiple clients in separate threads concurrently |
| * reading an AST and asking for bindings for its nodes. These requests all |
| * end up invoking instance methods on this class. There are various internal |
| * tables and caches which are built and maintained in the course of looking |
| * up bindings. To ensure that they remain coherent in the presence of multiple |
| * threads, the methods are synchronized on the DefaultBindingResolver instance. |
| * </p> |
| * |
| * Provisional API: This class/interface is part of an interim API that is still under development and expected to |
| * change significantly before reaching stability. It is being made available at this early stage to solicit feedback |
| * from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken |
| * (repeatedly) as the API evolves. |
