Detailed Description

template<typename T>
class vtkm::cont::ArrayHandleConstant< T >

An array handle with a constant value.

ArrayHandleConstant is an implicit array handle with a constant value. A constant array handle is constructed by giving a value and an array length. The resulting array is of the given size with each entry the same value given in the constructor. The array is defined implicitly, so there it takes (almost) no memory.
