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.

Associate name with pointer. If duplicates == 0 then do not allow duplicate name/pointer associations, else if duplicates != 0 then allow duplicate name/pointer associations. Returns 0 if successfully binds (1) a previously unbound name or (2) duplicates != 0, returns 1 if trying to bind a previously bound name and duplicates == 0, else returns -1 if a resource failure occurs.
Implements ACE_Allocator.

virtual |
Allocate nbytes, giving them initial_value.
Implements ACE_Allocator.
Reimplemented in ACE_Dynamic_Cached_Allocator< ACE_LOCK >, and ACE_Cached_Allocator< T, ACE_LOCK >.
|
virtual |
Allocate <n_elem> each of size elem_size, giving them initial_value.
Implements ACE_Allocator.
Reimplemented in ACE_Dynamic_Cached_Allocator< ACE_LOCK >, and ACE_Cached_Allocator< T, ACE_LOCK >.

Dump the state of the object.
Implements ACE_Allocator.
|
virtual |
Locate name and pass out parameter via pointer. If found, return 0, returns -1 if failure occurs.
Implements ACE_Allocator.
|
virtual |
Returns 0 if the name is in the mapping. -1, otherwise.
Implements ACE_Allocator.
|
virtual |
Free ptr (must have been allocated by ACE_Allocator::malloc()).
Implements ACE_Allocator.

These methods are defined.
Implements ACE_Allocator.
Reimplemented in ACE_Dynamic_Cached_Allocator< ACE_LOCK >, and ACE_Cached_Allocator< T, ACE_LOCK >.
Change the protection of the pages of the mapped region to prot starting at <this->base_addr_> up to len bytes. If len == -1 then change protection of all pages in the mapped region.
Implements ACE_Allocator.
|
virtual |
Change the protection of the pages of the mapped region to prot starting at addr up to len bytes.
Implements ACE_Allocator.
|
virtual |
These methods are no-ops.
Implements ACE_Allocator.
Sync len bytes of the memory region to the backing store starting at this->base_addr_
. If len == -1 then sync the whole region.
Implements ACE_Allocator.
|
virtual |
Sync len bytes of the memory region to the backing store starting at addr.
Implements ACE_Allocator.
|
virtual |
Associate name with pointer. Does not allow duplicate name/pointer associations. Returns 0 if successfully binds (1) a previously unbound name, 1 if trying to bind a previously bound name, or returns -1 if a resource failure occurs. When this call returns pointer's value will always reference the void * that name is associated with. Thus, if the caller needs to use pointer (e.g., to free it) a copy must be maintained by the caller.
Implements ACE_Allocator.
|
virtual |
Unbind (remove) the name from the map. Don't return the pointer to the caller
Implements ACE_Allocator.
|
virtual |
Break any association of name. Returns the value of pointer in case the caller needs to deallocate memory.
Implements ACE_Allocator.
