Re: [Boost-users] [statechart] Using fast_pool_allocator along withstate_machine

19 Apr 2008

      Hi
...
If I specified boost::fast_pool_allocator<int> does the library take care 
of somehow doing a rebind and allocating the right amount of memory for 
the states ?
Yes, please see:

<http://www.boost.org/doc/libs/1_35_0/libs/statechart/doc/faq.html#HardRealtime>
<http://www.boost.org/doc/libs/1_35_0/libs/statechart/doc/reference.html#ClassTemplatestate_machine>, 
Allocator parameter
<http://www.boost.org/doc/libs/1_35_0/libs/statechart/doc/reference.html#ClassTemplateevent>, 
Allocator parameter

...
struct Enabled;
struct Machine : sc::state_machine< Machine,
                    Enabled,
                    boost::fast_pool_allocator< int > > /* ??? is this 
right ? */
{
   Machine();
   ~Machine() {
       terminate();
   }
  int ContextAssociatedwithStateMachine;
};
Looks good to me. boost::fast_pool_allocator< int > is used in the 
performance example here:

HTH & Regards,
