Detailed Description

Stores a collection of weighting factors.

vtkArrayWeights provides storage for a collection of weights to be used when merging / interpolating N-way arrays. Convenience constructors are provided for working with one, two, three, and four weighting factors. For arbitrary collections of weights, use SetCount() and operator[] to assign values.

vtkArrayWeights is most commonly used with the vtkInterpolate() function to compute weighted sums of vtkArray objects.

(

)

Create an empty collection of weights

vtkArrayWeights::vtkArrayWeights

(

double

i

)

Create a collection containing one weight.

vtkArrayWeights::vtkArrayWeights	(	double	i,
		double	j
	)

Create a collection containing two weights.

vtkArrayWeights::vtkArrayWeights	(	double	i,
		double	j,

Member Function Documentation

vtkIdType vtkArrayWeights::GetCount

(

)

const

Returns the number of weights stored in this container.

void vtkArrayWeights::SetCount

(

vtkIdType

count

)

Sets the number of weights stored in this container. Note that each weight will be reset to 0.0 after calling SetCount(), use operator[] to assign the desired value for each weight.

double& vtkArrayWeights::operator[]

(

vtkIdType

)

Accesses the i-th weight in the collection.

const double& vtkArrayWeights::operator[]

(

vtkIdType

)

const

Accesses the i-th weight in the collection.
