| |
| |
| <p>This chapter gives you a brief overview about the SWIG |
| implementation of the C++17 standard. |
| There isn't much in C++17 that affects SWIG, however, work has only just begun on adding |
| C++17 support. |

| |
| |
| <p> |
| C++17 offers a more concise syntax for defining namespaces. |
| SWIG has support for nested namespace definitions such as: |
| </p> |
| |
| <div class="code"> |
| <pre> |
| namespace A::B::C { |
| ... |
| } |
| </pre> |
| </div> |
| |
| <p> |
| This is the equivalent to the C++98 namespace definitions: |
| </p> |
| |
| <div class="code"> |
| <pre> |
| namespace A { |
| namespace B { |
| namespace C { |
| ... |
| } |
| } |
| } |
| </pre> |
| </div> |
| |
| <p> |
| <b>Compatibility note:</b> SWIG-4.0.0 was the first version to support nested namespace definitions. |
