Define a simple "mark and release" memory allocation utility.

NAME

ACE_Obstack - Define a simple "mark and release" memory allocation utility.

SYNOPSIS

#include <ace/Obstack.h>
class ACE_Obstack
{
  public:
    ACE_Obstack (
        size_t size = 4096 - sizeof (ACE_Obchunk),
        ACE_Allocator *allocator_strategy = 0
        );
    ~ACE_Obstack (void);
    char *copy (const char *data, size_t len);
    void release (void);
    void dump (void) const;
    ACE_ALLOC_HOOK_DECLARE;
  protected:
    ACE_Allocator *allocator_strategy_;
    size_t size_;
};

DESCRIPTION

The implementation is similar to the GNU obstack utility, which is used extensively in the GCC compiler.

Initialization and termination methods.

ACE_Obstack (
    size_t size = 4096 - sizeof (ACE_Obchunk),
    ACE_Allocator *allocator_strategy = 0
    );


~ACE_Obstack (void);


char *copy (const char *data, size_t len);

Copy the data into the current Obchunk.

void release (void);

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

void dump (void) const;

Dump the state of an object.

ACE_ALLOC_HOOK_DECLARE;

Declare the dynamic allocation hooks.

Don't change the order of the following two fields.

Head of the Obchunk chain. Pointer to the current Obchunk.
