Detailed Description

template<class FunctorType>
class vtkm::cont::ArrayHandleImplicit< FunctorType >

An ArrayHandle that computes values on the fly.

ArrayHandleImplicit is a specialization of ArrayHandle. It takes a user defined functor which is called with a given index value. The functor returns the result of the functor as the value of this array at that position.
