|
|
The C++ STL allocator model has various flaws. For example, they are
|
|
fixed to a certain type, because they are almost necessarily required to
|
|
be templates. So you can't easily share a single allocator for multiple
|
|
types. In addition, you can only get a copy from the containers and not
|
|
the original allocator object. At least with C++11 they are allowed to be
|
|
stateful and so can be made object not instance based. But still, the
|
|
model has many flaws. Over the course of the years many solutions have
|
|
been proposed, for example EASTL. This library is another. But instead of
|
|
trying to change the STL, it works with the current implementation.
