# ACE\_Cached\_Allocator(3)

Create a cached memory poll with n\_chunks chunks each with sizeof (TYPE) size.

## NAME

ACE\_Cached\_Allocator -  Create a cached memory poll with n\_chunks chunks each with sizeof (TYPE) size.

## SYNOPSIS

```
#include <ace/Malloc_T.h>
template<class T, class ACE_LOCK>
class ACE_Cached_Allocator : public ACE_New_Allocator
{
  public:
    ACE_Cached_Allocator (size_t n_chunks);
    ~ACE_Cached_Allocator (void);
    void* malloc (size_t);
    void free (void *);
  private:
    char *pool_;
        ACE_Locked_Free_List<ACE_Cached_Mem_Pool_Node<T>, ACE_LOCK> free_list_;

};
```

## DESCRIPTION

This class enables caching of dynamically allocated, fixed-sized classes.

## PUBLIC MEMBERS

```
ACE_Cached_Allocator (size_t n_chunks);
```

Create a cached memory poll with n\_chunks chunks each with sizeof (TYPE) size.

```
~ACE_Cached_Allocator (void);
```

clear things up.

```
void* malloc (size_t);
```

get a chunk of memory from free store.

```
void free (void *);
```

return a chunk of memory back to free store.

## PRIVATE MEMBERS

```
char *pool_;
```

remember how we allocate the memory in the first place so we can clear things up later.

```
    ACE_Locked_Free_List<ACE_Cached_Mem_Pool_Node<T>, ACE_LOCK> free_list_;

```

Maintain a cached memory free list.
