Detailed Description

template<class VALUE_TYPE, class ALLOCATOR>
class bsl::Deque_Guard< VALUE_TYPE, ALLOCATOR >

This class provides a proctor that maintains a count of the number of elements constructed at the front or back of a deque, but not yet committed to the deque's range of valid elements; if the count is non-zero at destruction, the destructor destroys the elements in the range [d_deque_p->end() .. d_deque_p->end() + d_count), or the range [d_deque_p->begin() - d_count .. d_deque_p->begin()), depending on whether this proctor guards the back or front. This guard is used to undo element constructors in the event of an exception. It is up to the client code to increment the count whenever a new element is constructed and to decrement the count whenever d_start or d_finish of the guarded deque is moved to incorporate more elements.
