Constructor & Destructor Documentation

Measure() [1/2]

template<typename TSet >

DGtal::Measure< TSet >::Measure

(

)

Constructor.

~Measure()

template<typename TSet >

DGtal::Measure< TSet >::~Measure

(

)

Destructor.

Measure() [2/2]

template<typename TSet >

DGtal::Measure< TSet >::Measure ( const Measure< TSet > &  other )

private

Copy constructor.

Parameters

other

the object to clone. Forbidden by default.

Member Function Documentation

eval()

template<typename TSet >

Quantity DGtal::Measure< TSet >::eval

(

)

const

Compute the measure (area, volume) of the set. Since we rely on the Set::size() method which is O(1). The current method is O(1) too.

Precondition

init method must have been called before.

Returns

the measure of the set.

init()

template<typename TSet >

void DGtal::Measure< TSet >::init	(	const double	h,
		const Set &	aSetPointer
	)

Initialize the measure computation.

Parameters

h	grid size (must be >0).
aSetPointer	a pointer to an input set.

isValid()

template<typename TSet >

bool DGtal::Measure< TSet >::isValid

(

)

const

Checks the validity/consistency of the object.

Returns

'true' if the object is valid, 'false' otherwise.

operator=()

template<typename TSet >

Measure& DGtal::Measure< TSet >::operator= ( const Measure< TSet > &  other )

private

Assignment.

Parameters

other

the object to copy.

Returns

a reference on 'this'. Forbidden by default.

selfDisplay()

template<typename TSet >

void DGtal::Measure< TSet >::selfDisplay

(

std::ostream &

out

)

const

Writes/Displays the object on an output stream.

Parameters

out	the output stream where the object is written.

Field Documentation

myH

template<typename TSet >

double DGtal::Measure< TSet >::myH

private

grid resolution parameter.

Definition at line 156 of file Measure.h.

myIsInitBefore

template<typename TSet >

double DGtal::Measure< TSet >::myIsInitBefore

private

Boolean to assert that the init() was called before the eval().

Definition at line 162 of file Measure.h.

mySetSize

template<typename TSet >

Set::Size DGtal::Measure< TSet >::mySetSize

private

Copy of the set size.
