Description

template<typename ValueType>
class gmx::H5mdFixedDataSet< ValueType >

Class which provides an interface for reading and writing data to data sets of fixed size.

Template Parameters

ValueType

Type of values stored in data set (not limited to primitives).

Public Types
using	Base = H5mdDataSetBase< ValueType >

const DataSetDims & gmx::H5mdFixedDataSet< ValueType >::dims

(

)

const

Return the data set dimensions of the templated ValueType.

Note

For data sets of e.g. BasicVector<T> = T[3] this refers to the actual dimensions in terms of BasicVector<T>, not the base primitive T. So while data set with shape BasicVector<float>[30][50] has primitive dimensions float[30][50][3], the dimensions returned here are [30][50]. The returned dimensions are thus consistent with the size of input buffers ArrayRef<T> used for the I/O methods readData and writeData.

template<typename ValueType >

void gmx::H5mdFixedDataSet< ValueType >::readData

(

ArrayRef< ValueType >

data

)

const

Read all data from the data set into the given buffer data.

The size of the input data buffer must match that of the data set dims(). If the data set is multidimensional one must cast the data into a 1-dimensional form of row-major order.

Parameters

[out]

data

Buffer to read data into from the data set.

Exceptions

gmx::FileIOError

if the buffer size does not match the data set.

template<typename ValueType >

void gmx::H5mdFixedDataSet< ValueType >::writeData

(

ArrayRef< const ValueType >

data

)

const

Write to all values in the data set from the given buffer data.

The size of the input data buffer must match that of the data set dims(). If the data set is multidimensional one must cast the data into a 1-dimensional form of row-major order.

Parameters

[in]

data

Buffer with values to write into the data set.

Exceptions

gmx::FileIOError

if the buffer size does not match the data set.
