Detailed Description

template<size_t POOL_SIZE>
class ACE_Static_Allocator< POOL_SIZE >

Defines a class that provided a highly optimized memory management scheme for allocating memory statically.

This class allocates a fixed-size POOL_SIZE of memory and uses the ACE_Static_Allocator_Base class implementations of malloc() and calloc() to optimize memory allocation from this pool.
