Member Function Documentation

template<class CHAR>
CHAR * ACE_Obstack_T< CHAR >::copy const CHAR *    data,
size_t    len
 

Copy the data into the current Obchunk and freeze the current block. Return the starting address of the current building block, 0 if error occurs. len specify the string length, not the actually data size.

template<class CHAR>
void ACE_Obstack_T< CHAR >::dump void    const
 

Dump the state of an object.

template<class CHAR>
ACE_INLINE CHAR * ACE_Obstack_T< CHAR >::freeze void   
 

Freeze the current building block by null terminating it. Return the starting address of the current building block, 0 if error occurs.

template<class CHAR>
CHAR * ACE_Obstack_T< CHAR >::grow CHAR    c
 

Inserting a new CHAR c into the current building block without freezing (null terminating) the block. This function will create new chunk by checking the boundary of current Obchunk. Return the location c gets inserted to, or 0 if error.

template<class CHAR>
ACE_INLINE void ACE_Obstack_T< CHAR >::grow_fast CHAR    c
 

Inserting a new CHAR c into the current building block without freezing (null terminating) the block and without checking for out-of-bound error.

template<class CHAR>
ACE_INLINE size_t ACE_Obstack_T< CHAR >::length void    const
 

Return the maximum length or size of a string that can be put into this Obstack. size = length * sizeof (CHAR).

Deprecated : No need to use this function as you can put objects of arbitrary lengths into the obstack now.

template<class CHAR>
ACE_Obchunk * ACE_Obstack_T< CHAR >::new_chunk void    [protected]
 

template<class CHAR>
void ACE_Obstack_T< CHAR >::release void   
 

"Release" the entire stack of Obchunks, putting it back on the free list.

template<class CHAR>
int ACE_Obstack_T< CHAR >::request size_t    len
 

Request Obstack to prepare a block at least len long for building a new string. Return -1 if fail, 0 if success.

template<class CHAR>
ACE_INLINE size_t ACE_Obstack_T< CHAR >::size void    const
 

template<class CHAR>
void ACE_Obstack_T< CHAR >::unwind void *    obj
 

"Unwind" the stack. If obj is a null pointer, everything allocated in the stack is released. Otherwise, obj must be an address of an object allocated in the stack. In this case, obj is released along with everthing allocated in the Obstack since obj.

template<class CHAR>
void ACE_Obstack_T< CHAR >::unwind_i void *    obj [protected]
 

Search through the list of Obchunks and release them. Helper funtion used by unwind.
