Member Function Documentation

address() [1/2]

template<typename T >

__host__ __device__ pointer cugar::caching_device_allocator< T >::address ( reference  r )

inline

Returns the address of an allocated object.

Returns

&r.

address() [2/2]

template<typename T >

__host__ __device__ const_pointer cugar::caching_device_allocator< T >::address ( const_reference  r )

inline

Returns the address an allocated object.

Returns

&r.

allocate()

template<typename T >

CUGAR_HOST pointer cugar::caching_device_allocator< T >::allocate ( size_type  cnt, const_pointer  = const_pointer(static_cast<T*>(0))  )

inline

Allocates storage for cnt objects.

Parameters

cnt	The number of objects to allocate.

Returns

A pointer to uninitialized storage for cnt objects.

Note

Memory allocated by this function must be deallocated with deallocate.

deallocate()

template<typename T >

CUGAR_HOST void cugar::caching_device_allocator< T >::deallocate ( pointer  p, size_type  cnt  )

inline

Deallocates storage for objects allocated with allocate.

Parameters

p	A pointer to the storage to deallocate.
cnt	The size of the previous allocation.

Note

Memory deallocated by this function must previously have been allocated with allocate.
