Detailed Description

template<typename T>
class amr_wind::ViewField< T >

Subview of a Field or a ScratchField.

A ViewField instance holds MultiFab corresponding to a subview of a Field or a ScratchField. As the data is managed by the source Field or ScratchField, subview instances cannot be created directly but instead must be created using the Field::subview() and ScratchField::subview() methods.
