Detailed Description

template<typename T, typename ArrayHandleType>
class viskores::cont::ArrayHandleCast< T, ArrayHandleType >

Cast the values of an array to the specified type, on demand.

ArrayHandleCast is a specialization of ArrayHandleTransform. Given an ArrayHandle and a type, it creates a new handle that returns the elements of the array cast to the specified type.
