UniquePointer

using hdf5::dataspace::Selection::UniquePointer = std::unique_ptr<Selection>

As selections use virtual functions for being applied we have to

Constructor & Destructor Documentation

Selection() [1/2]

hdf5::dataspace::Selection::Selection ( )

default

Use the compiler provided default implementation.

Selection() [2/2]

hdf5::dataspace::Selection::Selection ( const Selection &  )

default

~Selection()

virtual hdf5::dataspace::Selection::~Selection ( )

virtual

The destructor has to be virtual to inherit from this class.

Member Function Documentation

apply()

virtual void hdf5::dataspace::Selection::apply ( const Dataspace &  space, SelectionOperation  ops  ) const

pure virtual

The current selection will be applied to dataspace space using the operator determined by ops.

Exceptions

std::runtime_error

in case of a failure

Parameters

space	reference to the dataspace onto which to apply the selection
ops	operator for the selection

Implemented in hdf5::dataspace::Points, and hdf5::dataspace::Hyperslab.

dimensions()

virtual Dimensions hdf5::dataspace::Selection::dimensions ( ) const

pure virtual

Get a number of elements along each dimension a selection spans this is particularly useful in the case of a Hyperslab

Exceptions

std::runtime_error

in case of a failure

Returns

the selection dimentsions

Implemented in hdf5::dataspace::Points, and hdf5::dataspace::Hyperslab.

size()

virtual size_t hdf5::dataspace::Selection::size ( ) const

pure virtual

Get the total number of elements adressed by an individual selection

Exceptions

std::runtime_error

in case of a failure

Returns

the selection type enumerator

Implemented in hdf5::dataspace::Points, and hdf5::dataspace::Hyperslab.

type()

virtual SelectionType hdf5::dataspace::Selection::type ( ) const

pure virtual

Get the type of the selection

Returns

the selection type enumerator

Implemented in hdf5::dataspace::Points, and hdf5::dataspace::Hyperslab.
