Classes
class	Opm::gpuistl::PointerView< T >
	A view towards a smart pointer to GPU-allocated memory. More...
class	Opm::gpuistl::PointerView< void >
	Specialization of PointerView for void type This is needed beause we cannot have a PointerView<void> specialization due to dereferincing a void ptr. More...
class	Opm::gpuistl::ValueAsPointer< T >
	A value stored with a pointer interface. Can be used to wrap objects in GPU kernels that were otherwise stored as pointers. More...

Namespaces
namespace	Opm
namespace	Opm::gpuistl
