TiledArray::detail::transform< T > Struct Template Reference

Documentation

template<typename T>
struct TiledArray::detail::transform< T >

customization point transform functionality to tensor class T, useful for nonintrusive extension of T to be usable as element type T in Tensor<T>

provides transform functionality to class T, useful for nonintrusive extension of a tensor type T to be usable as element type T in Tensor<T>

Template Parameters

T	a tensor type

Note

The default implementation constructs T, then computes it by coiterating over elements of the argument tensors and transforming with the transform Op . This should be specialized for classes like TiledArray::Tensor that already include the appropriate transform constructors already
