|
||||
|
||||
|
||||
<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.

||||
