Detailed Description

template<typename T>
struct hdf5::VarLengthStringTrait< T >

Trait implementing conversion functions between T and a particular variable length string buffer type.

Member Typedef Documentation

BufferType

template<typename T >

using hdf5::VarLengthStringTrait< T >::BufferType = VarLengthStringBuffer<char>

DataType

template<typename T >

using hdf5::VarLengthStringTrait< T >::DataType = T

Member Function Documentation

from_buffer()

template<typename T >

static void hdf5::VarLengthStringTrait< T >::from_buffer ( const BufferType &  , DataType &    )

inlinestatic

Copies data from the buffer to the user data structure. It assumes that data is allocated and all data fits into it. We usually do not have to care about this as during the reading procedure a dataspace for the data sturcture is created and H5Dread checks whether or not the data fits into the structure.

to_buffer()

template<typename T >

static BufferType hdf5::VarLengthStringTrait< T >::to_buffer ( const T &  )

inlinestatic

This function creates a buffer instance which can be used for writing data to disk. The buffer must be allocated within this function to ensure that all the input data fits into it.

Returns

an instance of the variable length string buffer
