Constructor & Destructor Documentation

graphlab::conditional::conditional ( const conditional &  )

inline

Copy constructor which does not copy. Do not use! Required for compatibility with some STL implementations (LLVM). which use the copy constructor for vector resize, rather than the standard constructor.

Definition at line 187 of file pthread_tools.hpp.
