This allocator implements the minimal interface to comply with section 17.6.3.5 ([allocator.requirements]) of the C++11 standard, while maintaining a distinct object state - in this case a wrapped pointer to a bslma::Allocator. The template is configurable to control its allocator propagation properties, but does not support the BDE "scoped" allocator model, as scoped allocators should never propagate. Instances of this allocator delegate their operations to the wrapped allocator that constitutes its state. Note that while we define the various traits used by the C++11 allocator traits facility, they actually mean very little for this component, as it is the consumer of the allocator's responsibility to check and apply the traits correctly, typically by using bsl::allocator_traits to perform all memory allocation tasks rather than using the allocator directly. The PROPAGATE_ON_CONTAINER_COPY_CONSTRUCTION flag is consumed directly though, in the static member function select_on_container_copy_construction.

Construct an object of the (template parameter) ELEMENT_TYPE, by forwarding the specified (variable number of) arguments to the corresponding constructor of ELEMENT_TYPE, at the specified uninitialized memory address. The behavior is undefined unless address is properly aligned for objects of ELEMENT_TYPE.

Return the maximum number of elements of type TYPE that can be allocated using this allocator in a single call to the allocate method. Note that there is no guarantee that attempts at allocating less elements than the value returned by max_size will not throw. *** DO NOT RELY ON THE CONTINUING PRESENT OF THIS METHOD *** THIS METHOD WILL BE REMOVED ONCE bslstl::allocator_traits PROPERLY DEDUCES AN IMPLEMENTATION FOR THIS FUNCTION WHEN NOT SUPPLIED BY THE ALLOCATOR DIRECTLY.
