Member Typedef Documentation

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 
)

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)

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 
)

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 ( void  )
virtual

Destructor.

Member Function Documentation

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

Returns the underlying allocator.

template<class MALLOC >
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 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.

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

Dump the state of the object.

Implements ACE_Allocator.

template<class MALLOC >
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 >
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 >
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 >
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 ( 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 >
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 >::remove ( void  )
virtual

Remove any resources associated with this memory manager.

Implements ACE_Allocator.

template<class MALLOC >
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 >
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 >
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 >
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.

template<class MALLOC >
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.
