Constructor & Destructor Documentation

◆ NDFileHDF5Dataset()

NDFileHDF5Dataset::NDFileHDF5Dataset ( asynUser *  pAsynUser,
const std::string &  name,
hid_t  dataset 
)

Constructor.

Parameters
[in]pAsynUser- asynUser that is used to control debugging output
[in]name- String name of the dataset.
[in]dataset- HDF5 handle to the dataset.

◆ ~NDFileHDF5Dataset()

NDFileHDF5Dataset::~NDFileHDF5Dataset ( )

Member Function Documentation

◆ configureCompression()

void NDFileHDF5Dataset::configureCompression ( Codec_t  codec)

Store codec definition.

Parameters
[in]codec- Codec definition.

◆ configureDims()

asynStatus NDFileHDF5Dataset::configureDims ( NDArray pArray,
bool  multiframe,
int  extradimensions,
int *  extra_dims,
int *  extra_dim_chunking,
int *  user_chunking 
)

configureDims.

Setup any extra dimensions required for this dataset

Parameters
[in]pArray- A pointer to an NDArray which contains dimension information.
[in]multiframe- Is this multiframe?
[in]extradimensions- The number of extra dimensions.
[in]extra_dims- The size of extra dimensions.
[in]extra_dim_chunking- Array of extra dimension chunking.
[in]user_chunking- Array of user defined chunking dimensions.

◆ extendDataSet() [1/2]

asynStatus NDFileHDF5Dataset::extendDataSet ( int  extradims)

extendDataSet.

Extend this dataset as necessary. If no extra dimensions are specified then the dataset is simply increased in the frame number direction.

Parameters
[in]extradims- The number of extra dimensions.

◆ extendDataSet() [2/2]

asynStatus NDFileHDF5Dataset::extendDataSet ( int  extradims,
hsize_t *  offsets 
)

◆ flushDataset()

asynStatus NDFileHDF5Dataset::flushDataset ( )

◆ getDim()

hsize_t NDFileHDF5Dataset::getDim ( int  index)

Return the requested dimension size.

Parameters
[in]indexof dimension
Returns
size of the dimension

◆ getHandle()

hid_t NDFileHDF5Dataset::getHandle ( )

getHandle.

Returns the HDF5 handle to this dataset.

◆ getMaxDim()

hsize_t NDFileHDF5Dataset::getMaxDim ( int  index)

Return the requested max dimension size.

Parameters
[in]indexof dimension
Returns
size of the dimension

◆ getOffset()

hsize_t NDFileHDF5Dataset::getOffset ( int  index)

Return the requested offset size.

Parameters
[in]indexof offset
Returns
size of the offset

◆ getVirtualDim()

hsize_t NDFileHDF5Dataset::getVirtualDim ( int  index)

Return the requested virtual dimension size.

Parameters
[in]indexof dimension
Returns
size of the dimension

◆ verifyChunking()

asynStatus NDFileHDF5Dataset::verifyChunking ( NDArray pArray)

Check if pArray dimensions and codec match hdf5 dataset definition.

Parameters
[in]pArray- The NDArray containing the data to verify.

◆ writeFile()

asynStatus NDFileHDF5Dataset::writeFile ( NDArray pArray,
hid_t  datatype,
hid_t  dataspace,
hsize_t *  framesize 
)

writeFile.

Write the data using the HDF5 library calls.

Parameters
[in]pArray- The NDArray containing the data to write.
[in]datatype- The HDF5 datatype of the data.
[in]dataspace- A handle to the HDF5 dataspace for this dataset.
[in]framesize- The size of the data to write.
