Function Documentation

data_size_in_bytes()

size_t data_size_in_bytes	(	pressio_dtype	type,
		size_t const	dimensions,
		size_t const	dims[]
	)

Parameters

[in]	type	the dtype of the data object
[in]	dimensions	the number of dimensions of the data object
[in]	dims	the actual of dimensions of the data object

Returns

the size of a data object in bytes

data_size_in_elements()

size_t data_size_in_elements	(	size_t	dimensions,
		size_t const	dims[]
	)

Parameters

[in]	dimensions	the number of dimensions of the data object
[in]	dims	the actual of dimensions of the data object

Returns

the size of a data object in elements

pressio_data_for_each() [1/4]

template<class ReturnType , class Function >

ReturnType pressio_data_for_each	(	pressio_data &	data,
		Function &&	f
	)

get beginning and end pointers for two input data values

Parameters

[in]	data	first input data set
[in]	f	templated function to call, it must return the same type regardless of the type of the inputs. it should have the signature template <class T> f(T* input_begin, T* input_end)

pressio_data_for_each() [2/4]

template<class ReturnType , class Function >

ReturnType pressio_data_for_each	(	pressio_data &	data,
		pressio_data &	data2,
		Function &&	f
	)

get beginning and end pointers for two input data values

Parameters

[in]	data	first input data set
[in]	data2	second input data set
[in]	f	templated function to call, it must return the same type regardless of the type of the inputs. it should have the signature template <class T, class U> ReturnType f(T* input_begin, T* input_end, T* input2_begin) where U is some type

pressio_data_for_each() [3/4]

template<class ReturnType , class Function >

ReturnType pressio_data_for_each	(	pressio_data const &	data,
		Function &&	f
	)

get beginning and end pointers for two input data values

Parameters

[in]	data	first input data set
[in]	f	templated function to call, it must return the same type regardless of the type of the inputs. it should have the signature template <class T> f(T* input_begin, T* input_end)

pressio_data_for_each() [4/4]

template<class ReturnType , class Function >

ReturnType pressio_data_for_each	(	pressio_data const &	data,
		pressio_data const &	data2,
		Function &&	f
	)

get beginning and end pointers for two input data values

Parameters

[in]	data	first input data set
[in]	data2	second input data set
[in]	f	templated function to call, it must return the same type regardless of the type of the inputs. it should have the signature template <class T, class U> ReturnType f(T* input_begin, T* input_end, T* input2_begin) where U is some type

pressio_new_free_fn()

template<class T >

pressio_data_delete_fn pressio_new_free_fn

(

)

pressio_data_delete_fn for handling deleting data allocated with new T[];
