/// \brief Set Type Specification |
|
/** |
|
This struct is used to specify a set specification. |
|
It is not a container, it is just a metaprogramming facility to |
|
express the type of a set. Generally, this specification will |
|
be used in other place to create a container. |
|
It has the same syntax that an std::vector instantiation, except |
|
that the allocator cannot be specified. The rationale behind |
|
this difference is that the allocator is not part of the set |
|
type specification, rather it is a container configuration |
|
parameter. |
|
The first parameter is the type of the objects in the set, and |
|
the second one is a Functor that compares them. |
|
Bimap binding metafunctions can be used with this class in |
|
the following way: |
|
|
|
\code |
|
using namespace support; |
|
|
|

|
