enum  mfem::MemoryClass {
  mfem::MemoryClass::HOST, mfem::MemoryClass::HOST_32, mfem::MemoryClass::HOST_64, mfem::MemoryClass::DEVICE,
 Memory classes identify sets of memory types. More...


bool mfem::IsHostMemory (MemoryType mt)
 Return true if the given memory type is in MemoryClass::HOST. More...
bool mfem::IsDeviceMemory (MemoryType mt)
 Return true if the given memory type is in MemoryClass::DEVICE. More...
MemoryType mfem::GetMemoryType (MemoryClass mc)
 Return a suitable MemoryType for a given MemoryClass. More...
bool mfem::MemoryClassContainsType (MemoryClass mc, MemoryType mt)
 Return true iff the MemoryType mt is contained in the MemoryClass mc. More...
MemoryClass mfem::operator* (MemoryClass mc1, MemoryClass mc2)
 Return a suitable MemoryClass from a pair of MemoryClasses. More...
void mfem::MemoryPrintFlags (unsigned flags)
 Print the state of a Memory object based on its internal flags. Useful in a debugger. See also Memory<T>::PrintFlags(). More...


constexpr int mfem::MemoryTypeSize = static_cast<int>(MemoryType::SIZE)
 Static casts to 'int' and sizes of some useful memory types. More...
