Constructor & Destructor Documentation

template<class MALLOC>
ACE_Allocator_Adapter< MALLOC >::ACE_Allocator_Adapter (  const char *    pool_name = 0 ) 
 

Note that pool_name should be located in a directory with the appropriate visibility and protection so that all processes that need to access it can do so.

template<class MALLOC>
ACE_Allocator_Adapter< MALLOC >::ACE_Allocator_Adapter (  const char *    pool_name,
const char *    lock_name,
MEMORY_POOL_OPTIONS    options = 0
)  [inline]
 

Note that pool_name should be located in a directory with the appropriate visibility and protection so that all processes that need to access it can do so. This constructor must be inline to avoid bugs with some C++ compilers.

template<class MALLOC>
ACE_Allocator_Adapter< MALLOC >::ACE_Allocator_Adapter (  const wchar_t *    pool_name ) 
 

Note that pool_name should be located in a directory with the appropriate visibility and protection so that all processes that need to access it can do so.

template<class MALLOC>
ACE_Allocator_Adapter< MALLOC >::ACE_Allocator_Adapter (  const wchar_t *    pool_name,
const wchar_t *    lock_name,
MEMORY_POOL_OPTIONS    options = 0
)  [inline]
 

Note that pool_name should be located in a directory with the appropriate visibility and protection so that all processes that need to access it can do so. This constructor must be inline to avoid bugs with some C++ compilers.

template<class MALLOC>
ACE_Allocator_Adapter< MALLOC >::~ACE_Allocator_Adapter (  void    )  [virtual]
 

Destructor.

Member Function Documentation

template<class MALLOC>
ACE_INLINE MALLOC & ACE_Allocator_Adapter< MALLOC >::alloc (  void    ) 
 

Returns the underlying allocator.

template<class MALLOC>
ACE_INLINE int ACE_Allocator_Adapter< MALLOC >::bind (  const char *    name,
void *    pointer,
int    duplicates = 0
)  [virtual]
 

Associate name with pointer. If duplicates == 0 then do not allow duplicate name/pointer associations, else if duplicates> != 0 then allow duplicate name/pointer assocations. 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.

template<class MALLOC>
ACE_INLINE void * ACE_Allocator_Adapter< MALLOC >::calloc (  size_t    n_elem,
size_t    elem_size,
char    initial_value = '\0'
)  [virtual]
 

Allocate n_elem each of size elem_size, giving them initial_value.

Implements ACE_Allocator.

template<class MALLOC>
ACE_INLINE void * ACE_Allocator_Adapter< MALLOC >::calloc (  size_t    nbytes,
char    initial_value = '\0'
)  [virtual]
 

Allocate nbytes, giving them all an initial_value.

Implements ACE_Allocator.

template<class MALLOC>
void ACE_Allocator_Adapter< MALLOC >::dump (  void    )  const [virtual]
 

Dump the state of the object.

Implements ACE_Allocator.

template<class MALLOC>
ACE_INLINE int ACE_Allocator_Adapter< MALLOC >::find (  const char *    name )  [virtual]
 

Returns 0 if the name is in the mapping and -1 if not.

Implements ACE_Allocator.

template<class MALLOC>
ACE_INLINE int ACE_Allocator_Adapter< MALLOC >::find (  const char *    name,
void *&    pointer
)  [virtual]
 

Locate name and pass out parameter via pointer. If found, return 0, returns -1 if name isn't found.

Implements ACE_Allocator.

template<class MALLOC>
ACE_INLINE void ACE_Allocator_Adapter< MALLOC >::free (  void *    ptr )  [virtual]
 

Free ptr (must have been allocated by ACE_Allocator::malloc()).

Implements ACE_Allocator.

template<class MALLOC>
ACE_INLINE void * ACE_Allocator_Adapter< MALLOC >::malloc (  size_t    nbytes )  [virtual]
 

Allocate nbytes, but don't give them any initial value.

Implements ACE_Allocator.

template<class MALLOC>
int ACE_Allocator_Adapter< MALLOC >::protect (  void *    addr,
size_t    len,
int    prot = PROT_RDWR
)  [virtual]
 

Change the protection of the pages of the mapped region to prot starting at addr up to len bytes.

Implements ACE_Allocator.

template<class MALLOC>
int ACE_Allocator_Adapter< MALLOC >::protect (  ssize_t    len = -1,
int    prot = PROT_RDWR
)  [virtual]
 

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.

template<class MALLOC>
ACE_INLINE int ACE_Allocator_Adapter< MALLOC >::remove (  void    )  [virtual]
 

Remove any resources associated with this memory manager.

Implements ACE_Allocator.

template<class MALLOC>
ACE_INLINE int ACE_Allocator_Adapter< MALLOC >::sync (  void *    addr,
size_t    len,
int    flags = MS_SYNC
)  [virtual]
 

Sync len bytes of the memory region to the backing store starting at addr_.

Implements ACE_Allocator.

template<class MALLOC>
ACE_INLINE int ACE_Allocator_Adapter< MALLOC >::sync (  ssize_t    len = -1,
int    flags = MS_SYNC
)  [virtual]
 

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.

template<class MALLOC>
ACE_INLINE int ACE_Allocator_Adapter< MALLOC >::trybind (  const char *    name,
void *&    pointer
)  [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.

template<class MALLOC>
ACE_INLINE int ACE_Allocator_Adapter< MALLOC >::unbind (  const char *    name,
void *&    pointer
)  [virtual]
 

Break any association of name. Returns the value of pointer in case the caller needs to deallocate memory.

Implements ACE_Allocator.

template<class MALLOC>
ACE_INLINE int ACE_Allocator_Adapter< MALLOC >::unbind (  const char *    name )  [virtual]
 

Unbind (remove) the name from the map. Don't return the pointer to the caller

Implements ACE_Allocator.
