Detailed Description

template<typename T>
class iolink::RegionX< T >

A Region using dynamic vectors.

Constructor & Destructor Documentation

RegionX()

template<typename T >

iolink::RegionX< T >::RegionX ( size_t  dimension )

explicit

Creates an empty region.

Parameters

dimension

The dimension of the region.

Member Function Documentation

contains() [1/2]

template<typename T >

bool iolink::RegionX< T >::contains

(

const RegionX< T > &

other

)

const

Checks if this region conatins another.

Exceptions

InvalidArgument

if region don't have compatible dimensions

contains() [2/2]

template<typename T >

bool iolink::RegionX< T >::contains

(

const VectorType &

position

)

const

Checks if this region contains a point.

Exceptions

InvalidArgument

if region don't have compatible dimensions

elementCount()

template<typename T >

size_t iolink::RegionX< T >::elementCount

(

)

const

Returns the number of cells in this region.

Only applicable to integer typed regions. It will return 0 for floating point regions.

extractSliceFromAxis()

template<typename T >

RegionX iolink::RegionX< T >::extractSliceFromAxis	(	size_t	dimension,
		T	origin
	)		const

Returns a region of size one along one axis.

Parameters

dimension	axis on which the slice must be selected
origin	position of slice in given dimension

Returns

the slice at given position for given dimension

Exceptions

InvalidArgument

if dimension or origin are out of range

e.g. a 3D region {{0, 0, 0}, {5, 6, 7}}

• extractSliceFromAxis(0, 3) returns 3D region {{3, 0, 0}, {1, 6, 7}}
• extractSliceFromAxis(1, 4) returns 3D region {{0, 4, 0}, {5, 1, 7}}
• extractSliceFromAxis(2, 5) returns 3D region {{0, 0, 5}, {5, 6, 1}}

e.g. a 3D region with non-null origin { {2, 3, 4}, {5, 6, 7}}

extractSliceFromAxis(0, 3) returns 3D region {{5, 3, 4}, {1, 6, 7}}

intersect()

template<typename T >

bool iolink::RegionX< T >::intersect

(

const RegionX< T > &

other

)

const

Checks if this region intersect another.

Exceptions

InvalidArgument

if region don't have compatible dimensions

intersection()

template<typename T >

RegionX iolink::RegionX< T >::intersection

(

const RegionX< T > &

other

)

const

Returns the intersection of this region and another.

If regions does not intersect, it returns an empty region.

Exceptions

InvalidArgument

if region don't have compatible dimensions

isEmpty()

template<typename T >

bool iolink::RegionX< T >::isEmpty

(

)

const

Checks if the region is empty.

An integer typed region is empty if one of its sizes is 0. A floating point region is empty is one of its sizes is Nan.

min()

template<typename T >

VectorType iolink::RegionX< T >::min

(

)

const

Returns the minimal point of the region.

Alias for origin.
