Detailed Description

Implementations of the STL allocator concept.

Function Documentation

allocate() [1/2]

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.

allocate() [2/2]

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.

construct()

template<class T , std::size_t s>

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

inline

Construct an object.

Parameters

p	Pointer to the object.
value	The value to initialize it to.

deallocate()

template<class T , std::size_t s>

void Dune::PoolAllocator< T, s >::deallocate ( pointer  p, std::size_t  n  )

inline

Free objects.

Does not call the destructor!

Parameters

n	The number of objects to free. Has to be one!
p	Pointer to the first object.

destroy()

template<class T , std::size_t s>

void Dune::PoolAllocator< T, s >::destroy ( pointer  p )

inline

Destroy an object without freeing memory.

Parameters

p	Pointer to the object.

free()

template<class T , std::size_t S>

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

inline

Free an object.

Parameters

o	The pointer to memory block of the object.
