Re: [Boost-users] Boost pool and move constructor

Nice! Thanks! About the destroy, can I simple call myPool.destroy(obj) ? Best Regards Bruno Sanches ======================== http://www.pontov.com.br On Tue, May 6, 2014 at 12:32 PM, Gabriel Redner wrote:

Hi Bruno,

You can work around this problem by using malloc/free to manage the memory, and then creating and destroying the object yourself.

void *mem = myPool.malloc(); Object *obj = new (mem) Object(args);

Then to destroy:

obj->~Object(); myPool.free(obj);

I am trying to create a object using boost object_pool, but trying to use the move constructor of the desired object, but on Visual 2013, I am always getting:

error C2664: 'MyObject::MyObject(const MyObject &)' : cannot convert argument 1 from 'MyObject (__cdecl &)(void)' to 'MyObject &&'

The error happens because boost pool construct method always assume a const parameter.

Sample code:

#include class MyObject{ public: MyObject(): m_iData(0) {

}

MyObject(MyObject &&other): m_iData(std::move(other.m_iData)) { other.m_iData = 0; }

MyObject(const MyObject &rhs) = delete;

MyObject &operator=(const MyObject &rhs) = delete;

private: int m_iData;}; int main(int, char**){ boost::object_pool<MyObject> pool;

MyObject obj;

MyObject *pObj = pool.construct(std::move(obj));}

Is there any way to invoke the move constructor using boost::object_pool?
