Detailed Description

template<typename T>
class stapl::runtime::arg_storage< T >

Storage for an object of type T that is retrieved by lvalue reference.

Template Parameters

T	Object type.

Constructor & Destructor Documentation

arg_storage() [1/2]

template<typename T >

stapl::runtime::arg_storage< T >::arg_storage ( T const &  t, void *const  base, std::size_t &  size  )

noexcept

Constructs a new object by packing t in it.

This constructor will copy the dynamic part of the object at base + size, which should be big enough to fit it.

Parameters

t	Object to pack.
base	Pointer to buffer start where the dynamic part of t can be stored in.
size	Offset from base where space is available.

arg_storage() [2/2]

template<typename T >

template<typename Tuple >

stapl::runtime::arg_storage< T >::arg_storage ( Tuple &&  t )

noexcept

Packs the object contained in tuple t.

Parameters

t	Tuple with the object to pack, the start of the buffer for the dynamic part of the object and the offset from the start of the buffer.

Member Function Documentation

get() [1/2]

template<typename T >

T& stapl::runtime::arg_storage< T >::get

(

void *const

base

)

Returns the stored object after unpacking it.

Parameters

base	Buffer where the dynamic part of the object is stored.

get() [2/2]

template<typename T >

T& stapl::runtime::arg_storage< T >::get	(	void *const	base,
		std::size_t &	size
	)

Returns the stored object after unpacking it.

Parameters

base	Buffer where the dynamic part of the object is stored.
size	Variable to store how many bytes were unpacked.
