Member Typedef Documentation

As of C++14, std::set::find() can be a templated overload.

https://en.cppreference.com/w/cpp/container/set/find We enable this by defining is_transparent as a type.

Definition at line 510 of file utility.h.

template<class T >

bool libMesh::Utility::CompareUnderlying::operator()	(	const std::unique_ptr< T > &	a,
		const std::unique_ptr< T > &	b
	)		const

inline

This is already what the default operator< comparison for std::unique_ptrs does, we are not adding anything here.
