Detailed Description

template<typename ComponentsArrayHandleType, vtkm::IdComponent NUM_COMPONENTS>
class vtkm::cont::ArrayHandleGroupVec< ComponentsArrayHandleType, NUM_COMPONENTS >

Fancy array handle that groups values into vectors.

It is sometimes the case that an array is stored such that consecutive entries are meant to form a group. This fancy array handle takes an array of values and a size of groups and then groups the consecutive values stored in a Vec.

For example, if you have an array handle with the six values 0,1,2,3,4,5 and give it to a ArrayHandleGroupVec with the number of components set to 3, you get an array that looks like it contains two values of Vec values of size 3 with the data [0,1,2], [3,4,5].

The array of components should have a number of values that divides evenly with the size of the Vec. If the components array does not divide evenly into Vecs, then a warning will be logged and the extra component values will be ignored.
