Function Documentation

template<class T , std::size_t S>

void * Dune::Pool< T, S >::allocate ( )

inline

Get a new or recycled object.

Returns

A pointer to the object memory.

template<class T , std::size_t s>

PoolAllocator< T, s >::pointer Dune::PoolAllocator< T, s >::allocate ( std::size_t  n, const_pointer  hint = 0  )

inline

Allocates objects.

Parameters

n	The number of objects to allocate. Has to be one!
hint	Ignored hint.

Returns

A pointer tp the allocated elements.

template<class T , std::size_t s>

void Dune::PoolAllocator< T, s >::construct ( pointer  p, const_reference  value  )

inline

Construct an object.

Parameters
