Detailed Description

template<class TYPE>
template<class VECTOR>
class bdlcc::Deque< TYPE >::VectorThrowGuard< VECTOR >

This private class is used to manage one vector object during the course of an operation by a bdlcc::Deque. Because it has a release method, it is actually a proctor, but we call it a guard to avoid having clients confuse it with the Proctor and ConstProctor types. The vector may only grow by having objects appended to it. If a throw happens during the course of the operation and the guard's destructor is called while still managing the object, it will restore the managed object to its initial state via operations that are guaranteed not to throw.

See Component bdlcc_deque
