- * @class ACE_New_Allocator
- *
- * @brief Defines a class that provided a simple implementation of
- * memory allocation.
- *
- * This class uses the new/delete operators to allocate and free up
- * memory. Please note that the only methods that are supported are
- * <malloc>, <calloc>, and <free>. All other methods are no-ops that
- * return -1 and set <errno> to <ENOTSUP>. If you require this
- * functionality, please use: ACE_Allocator_Adapter <ACE_Malloc
- * <ACE_LOCAL_MEMORY_POOL, MUTEX> >, which will allow you to use the
- * added functionality of bind/find/etc. while using the new/delete
- * operators.

- * @class ACE_Static_Allocator_Base
- *
- * @brief Defines a class that provided a highly optimized memory
- * management scheme for allocating memory statically.
- *
- * This class manages a fixed-size <POOL_SIZE> of memory. Every
- * time <malloc>/<calloc> is called, it simply moves an internal
- * index forward and returns a pointer to the requested chunk.
- * All memory is allocated statically (typically via the
- * <ACE_Static_Allocator> template) and <free> is a no-op. This
- * behavior is useful for use-cases where all the memory
- * allocation needs are known in advance and no deletions ever
- * occur.
