pni::io::nx::write_visitor< ATYPE, GTYPE, FTYPE, AATYPE, LTYPE >::write_visitor ( const ATYPE &  data, const selection_t &  s = selection_t()  )

Parameters

data	reference to the data holding instance
s	selection of what to write

Member Function Documentation

result_type pni::io::nx::write_visitor< ATYPE, GTYPE, FTYPE, AATYPE, LTYPE >::operator() ( const group_type &  ) const

inline

Cannot write data to a group - thus an exception is thrown.

Exceptions

nxgroup_error

Parameters

g	group instance

Returns

nothing

result_type pni::io::nx::write_visitor< ATYPE, GTYPE, FTYPE, AATYPE, LTYPE >::operator() ( const field_type &  f ) const

inline

Write data to a field

Exceptions

shape_mismatch_error	if selection and field rank do not match
invalid_object_error	if the field is not valid
io_error	if writing the data fails
type_error	if the data type of ATYPE is not supported
memory_not_allocated_error	if ATYPE is an array type and its internal buffer has no memory associated with it
size_mismatch_error	if the number of elements of ATYPE and the field do not match
object_error	in case of any other error

Parameters

f	field instance

Returns

nothing

template<typename ATYPE , typename GTYPE , typename FTYPE , typename AATYPE , typename LTYPE >

result_type pni::io::nx::write_visitor< ATYPE, GTYPE, FTYPE, AATYPE, LTYPE >::operator() ( const attribute_type &  a ) const

inline

Write data to an attribute. If the selection member is not empty an exception will be thrown as partial IO is not supported on attributes.

Exceptions

invalid_object_error	if the field is not valid
io_error	if reading the data fails
type_error	if the data type of ATYPE is not supported or the selection is not empty
memory_not_allocated_error	if ATYPE is an array type and its internal buffer has no memory associated with it
size_mismatch_error	if the number of elements of ATYPE and the field do not match
object_error	in case of any other error

Parameters

a	attribute instance

Returns

nothing

result_type pni::io::nx::write_visitor< ATYPE, GTYPE, FTYPE, AATYPE, LTYPE >::operator() ( const link_type &  ) const

inline

Cannot write data to a link - thus an exception is thrown.

Exceptions

type_error
