Public Types

typedef ACE_Local_Memory_Pool_Options OPTIONS

Public Methods

 ACE_Local_Memory_Pool (const ACE_TCHAR *backing_store_name = 0, const OPTIONS *options = 0)
 Initialize the pool.

virtual ~ACE_Local_Memory_Pool (void)
virtual void* init_acquire (size_t nbytes, size_t &rounded_bytes, int &first_time)
 Ask system for initial chunk of local memory.

virtual void* acquire (size_t nbytes, size_t &rounded_bytes)
 Acquire at least NBYTES from the memory pool. ROUNDED_BYTES is the actual number of bytes allocated.

virtual int release (void)
 Instruct the memory pool to release all of its resources.

virtual int sync (ssize_t len = -1, int flags = MS_SYNC)
virtual int sync (void *addr, size_t len, int flags = MS_SYNC)
 Sync <len> bytes of the memory region to the backing store starting at .

virtual int protect (ssize_t len = -1, int prot = PROT_RDWR)
virtual int protect (void *addr, size_t len, int prot = PROT_RDWR)
 Change the protection of the pages of the mapped region to <prot> starting at up to <len> bytes.

virtual int seh_selector (void *)
virtual int remap (void *addr)
virtual void dump (void) const
 Dump the state of an object.


Public Attributes

 ACE_ALLOC_HOOK_DECLARE
 Declare the dynamic allocation hooks.


Protected Methods

Protected Attributes

ACE_Unbounded_Set<char *> allocated_chunks_
 List of memory that we have allocated.

Constructor & Destructor Documentation

ACE_Local_Memory_Pool::ACE_Local_Memory_Pool ( const ACE_TCHAR * backing_store_name = 0,
const OPTIONS * options = 0 )
 

Initialize the pool.

Member Function Documentation

void * ACE_Local_Memory_Pool::acquire ( size_t nbytes,
size_t & rounded_bytes ) [virtual]
 

Acquire at least NBYTES from the memory pool. ROUNDED_BYTES is the actual number of bytes allocated.

void ACE_Local_Memory_Pool::dump ( void ) const [virtual]
 

Dump the state of an object.

ACE_INLINE void * ACE_Local_Memory_Pool::init_acquire ( size_t nbytes,
size_t & rounded_bytes,
int & first_time ) [virtual]
 

Ask system for initial chunk of local memory.

ACE_INLINE int ACE_Local_Memory_Pool::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 up to <len> bytes.

ACE_INLINE int ACE_Local_Memory_Pool::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.

int ACE_Local_Memory_Pool::release ( void ) [virtual]
 

Instruct the memory pool to release all of its resources.

int ACE_Local_Memory_Pool::remap ( void * addr ) [virtual]
 

Try to extend the virtual address space so that is now covered by the address mapping. Always returns 0 since we can't remap a local memory pool.

ACE_INLINE size_t ACE_Local_Memory_Pool::round_up ( size_t nbytes ) [protected, virtual]
 

int ACE_Local_Memory_Pool::seh_selector ( void * ) [virtual]
 

Win32 Structural exception selector. The return value decides how to handle memory pool related structural exceptions. Returns 1, 0, or , -1.

ACE_INLINE int ACE_Local_Memory_Pool::sync ( void * addr,
size_t len,
int flags = MS_SYNC ) [virtual]
 

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

ACE_INLINE int ACE_Local_Memory_Pool::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.

ACE_Local_Memory_Pool::ACE_ALLOC_HOOK_DECLARE
 

Declare the dynamic allocation hooks.

ACE_Unbounded_Set< char *> ACE_Local_Memory_Pool::allocated_chunks_ [protected]
