| Name| Description
| xref:BloombergLP/bslma/DeleterHelper/deleteObject.adoc[`deleteObject`] 
| Destroy the specified `object` based on its dynamic type and then use the specified `allocator` to deallocate its memory footprint. Do nothing if `object` is a null pointer. The behavior is undefined unless `allocator` is non‐null, and `object`, when cast appropriately to `void *`, was allocated using `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.
| xref:BloombergLP/bslma/DeleterHelper/deleteObjectRaw.adoc[`deleteObjectRaw`] 
| Destroy the specified `object` and then use the specified `allocator` to deallocate its memory footprint. Do nothing if `object` is a null pointer. The behavior is undefined unless `allocator` is non‐null, `object` is *not* a secondary base class pointer (i.e., the address is (numerically) the same as when it was originally dispensed by `allocator`), and `object` was allocated using `allocator` and has not already been deallocated.
