[Boost-users] shared container class with read/write mutex

Hi everyone, can anyone send a simple container class implementation, which
supports concurrent reads and exclusive write. I'm seeking for the usage of
shared_lock for read/write mutex. My simple template class snippet is shown
below, please reply how to fill the comments for locking. Thnx.

 

 

// std includes

#include <vector>

 

// boost includes

#include <boost/thread/shared_mutex.hpp>

 

template <typename T>

class SharedContainer

{

public:

       SharedContainer (void){}

       ~SharedContainer (void){}

       

       void push_back(const T& value);       

       const T& at(int index) const;

 

private:

       std::vector<T> m_buffer;

       boost::shared_mutex rw_mutex; //is this the correct class for rw
mutex?

};

 

template <typename T>

void EntityUpdateBuffer<T>::push_back( const T& value )

{

       // how to acquire a write lock?

 

       m_buffer.push_back(value);

}

 

template <typename T>

const T& EntityUpdateBuffer<T>::at( int index ) const

{

       // how to acquire read lock?

 

       return m_buffer.at(index);

}
