std::string name(const ElemQuality q)
ReferenceCountedObject(ReferenceCountedObject &&other) noexcept
Move constructor, must be declared noexcept.
void increment_constructor_count(const std::string &name)
Increments the construction counter.
ReferenceCountedObject & operator=(const ReferenceCountedObject &)
Copy assignment operator does nothing - we&#39;re copying an already-allocated object over an already-all...
The libMesh namespace provides an interface to certain functionality in the library.
This is the base class for enabling reference counting.
ReferenceCountedObject(const ReferenceCountedObject &other)
Also, increment the counter if the copy-constructor is called.
void increment_destructor_count(const std::string &name)
Increments the destruction counter.
ReferenceCounter()
Constructors.
This class implements reference counting.
