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.

Member Function Documentation

GetCount()

vtkIdType vtkArrayWeights::GetCount

(

)

const

Returns the number of weights stored in this container.

SetCount()

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.

operator[]() [1/2]

double& vtkArrayWeights::operator[]

(

vtkIdType

)

Accesses the i-th weight in the collection.

operator[]() [2/2]

const double& vtkArrayWeights::operator[]

(

vtkIdType

)

const

Accesses the i-th weight in the collection.

operator=()

vtkArrayWeights& vtkArrayWeights::operator=

(

const vtkArrayWeights &

other

)

Assignment operator.
