Detailed Description
class NullAllocator< T >
NULL allocator.
- Template Parameters
-
T class or type
A NullAllocator is useful for fixed-size, stack based allocations (i.e., static arrays used by FixedSizeAllocatorWithCleanup).
A NullAllocator always returns 0 for max_size(), and always returns NULL for allocation requests. Though the allocator does not allocate at runtime, it does perform a secure wipe or zeroization during cleanup.
