Functions

template<typename T >
MemoryClass mfem::GetMemoryClass (const Memory< T > &mem, bool on_dev)
 Return the memory class to be used by the functions Read(), Write(), and ReadWrite(), while setting the device use flag in mem, if on_dev is true. More...
 
template<typename T >
const T * mfem::Read (const Memory< T > &mem, int size, bool on_dev=true)
 Get a pointer for read access to mem with the mfem::Device's DeviceMemoryClass, if on_dev = true, or the mfem::Device's HostMemoryClass, otherwise. More...
 
template<typename T >
const T * mfem::HostRead (const Memory< T > &mem, int size)
 Shortcut to Read(const Memory<T> &mem, int size, false) More...
 
template<typename T >
T * mfem::Write (Memory< T > &mem, int size, bool on_dev=true)
 Get a pointer for write access to mem with the mfem::Device's DeviceMemoryClass, if on_dev = true, or the mfem::Device's HostMemoryClass, otherwise. More...
 
template<typename T >
T * mfem::HostWrite (Memory< T > &mem, int size)
 Shortcut to Write(const Memory<T> &mem, int size, false) More...
 
template<typename T >
T * mfem::ReadWrite (Memory< T > &mem, int size, bool on_dev=true)
 Get a pointer for read+write access to mem with the mfem::Device's DeviceMemoryClass, if on_dev = true, or the mfem::Device's HostMemoryClass, otherwise. More...
 
template<typename T >
T * mfem::HostReadWrite (Memory< T > &mem, int size)
 Shortcut to ReadWrite(Memory<T> &mem, int size, false) More...
