Constructor & Destructor Documentation

◆ base_list() [1/3]

base_list::base_list ( )
inline

◆ base_list() [2/3]

base_list::base_list ( const base_list tmp)
inline

This is a shallow copy constructor that implicitly passes the ownership from the source list to the new instance.

The old instance is not updated, so both objects end up sharing the same nodes. If one of the instances then adds or removes a node, the other becomes out of sync ('last' pointer), while still operational. Some old code uses and relies on this behaviour. This logic is quite tricky: please do not use it in any new code.

◆ base_list() [3/3]

base_list::base_list ( const base_list rhs,
MEM_ROOT mem_root 
)

Construct a deep copy of the argument in memory root mem_root.

The elements themselves are copied by pointer.
