Detailed Description

This class provides an convenient interface to a chunked dataset. As a matter of fact the only thing added here is a convenient constructor where the chunk shape can be passed as an additional argument.

Constructor & Destructor Documentation

◆ ChunkedDataset() [1/3]

hdf5::node::ChunkedDataset::ChunkedDataset ( )

default

Required for STL compliance. We can use the compiler provided default implementation here.

◆ ChunkedDataset() [2/3]

hdf5::node::ChunkedDataset::ChunkedDataset ( const ChunkedDataset & )

default

Required for STL compliance. We can use the compiler provided default implementation here.

◆ ChunkedDataset() [3/3]

hdf5::node::ChunkedDataset::ChunkedDataset	(	const Group &	base,
		const Path &	path,
		const datatype::Datatype &	type,
		const dataspace::Simple &	space,
		const Dimensions &	chunk_shape,
		const property::LinkCreationList &	lcpl = `property::LinkCreationList()`,
		const property::DatasetCreationList &	dcpl = `property::DatasetCreationList()`,
		const property::DatasetAccessList &	dapl = `property::DatasetAccessList()`
	)

As for all dataset constructors, references to the required property list can be passed as optional arguments. There are two things worth noting here

the dataspace for a chunked dataset must be a simple dataspace
independent of the configuration of an eventually user provided dataset creation property list, the layout of the dataset will be chunked with the provided chunk shape.

The user provided dataset creation property list will not be changed.

Exceptions

std::runtime_error in case of a failure

Parameters

base	the base object for the dataset creation
path	the path to the new dataset
type	optional reference to a datatype
space	optional reference to a dataspace
chunk_shape	reference to the chunk shape
lcpl	optional reference to a link creation property list
dcpl	optional reference to a dataset creation property list
dapl	optional reference to a dataset access property list
