Polymorphic wrapper around an object of the specified STL_ALLOC
STL-style allocator template parameter. A pointer to an object of this class can thus be used with any component that uses BDE-style memory allocation. Note that AllocatorAdaptor<A>Type
is the same type regardless of whether or not the compiler supports alias templates. It should be used, therefore, whenever the exact type of the adaptor is important.

virtual void* bslma::AllocatorAdaptor_Imp< STL_ALLOC >::allocate | ( | size_type | size | ) | [virtual, inherited] |
Return a maximally-aligned block of memory no smaller than size
bytes allocated from the STL-style allocator that was supplied to this object's constructor. Any exceptions thrown by the underlying STL-style allocator are propagated out from this member.
Implements bslma::Allocator.
virtual void bslma::AllocatorAdaptor_Imp< STL_ALLOC >::deallocate | ( | void * | address | ) | [virtual, inherited] |
Return the memory block at the specified address
back to the STL-allocator. If address
is null, this funciton has no effect. The behavior is undefined unless address
was allocated using this allocator object and has not already been deallocated.
Implements bslma::Allocator.
STL_ALLOC bslma::AllocatorAdaptor_Imp< STL_ALLOC >::adaptedAllocator | ( | ) | const [inherited] |
Return a copy of the STL allocator stored within this object.
static void bslma::Allocator::throwBadAlloc | ( | ) | [static, inherited] |
DEPRECATED: Use bsls::BslExceptionUtil::throwBadAlloc
instead.
Throw std::bad_alloc
if exceptions are enabled or abort the program otherwise. Derived classes and helper functions will typically call this function when they are unable to satisfy an allocation request. This function never returns.
void bslma::Allocator::deleteObject | ( | const TYPE * | object | ) | [inherited] |
Destroy the specified object
based on its dynamic type and then use this allocator to deallocate its memory footprint. Do nothing if object
is a null pointer. The behavior is undefined unless object
, when cast appropriately to void *
, was allocated using this allocator and has not already been deallocated. Note that dynamic_cast<void *>(object)
is applied if TYPE
is polymorphic, and static_cast<void *>(object)
is applied otherwise.
void bslma::Allocator::deleteObject | ( | bsl::nullptr_t | ) | [inherited] |
This function has no effect. Note that it exists to support calling deleteObject
will a null pointer literal, that would otherwise not deduce to a pointer type for the method above. As calls to deleteObject
with (typed) null pointer values have well-defined behavior, it should also support calls with a null pointer literal.
void bslma::Allocator::deleteObjectRaw | ( | const TYPE * | object | ) | [inherited] |
Destroy the specified object
and then use this allocator to deallocate its memory footprint. Do nothing if object
is a null pointer. The behavior is undefined unless object
was allocated using this allocator, is not a secondary base class pointer -- i.e., the address is (numerically) the same as when it was originally dispensed by this allocator, and has not already been deallocated.
void bslma::Allocator::deleteObjectRaw | ( | bsl::nullptr_t | ) | [inherited] |
This function has no effect. Note that it exists to support calling deleteObjectRaw
will a null pointer literal, that would otherwise not deduce to a pointer type for the method above. As calls to deleteObjectRaw
with (typed) null pointer values have well-defined behavior, it should also support calls with a null pointer literal.
