ACE_Locked_Free_List (const ACE_Locked_Free_List< T, ACE_LOCK > &) | |
void | operator= (const ACE_Locked_Free_List< T, ACE_LOCK > &) |
This class maintains a free list of nodes of type T. It depends on the type T having a <get_next> and <set_next> method. It maintains a mutex so the freelist can be used in a multithreaded program .

Constructor takes a mode (i.e., ACE_FREE_LIST_WITH_POOL or ACE_PURE_FREE_LIST), a count of the number of nodes to <prealloc>, a low and high water mark (<lwm> and <hwm>) that indicate when to allocate more nodes, an increment value (<inc>) that indicates how many nodes to allocate when the list must grow.
ACE_Locked_Free_List< T, ACE_LOCK >::~ACE_Locked_Free_List | ( | void | ) | [inline, virtual] |
Destructor - removes all the elements from the free_list.

void ACE_Locked_Free_List< T, ACE_LOCK >::add | ( | T * | element | ) | [inline, virtual] |
Inserts an element onto the free list (if it isn't past the high water mark).
Implements ACE_Free_List< T >.
T * ACE_Locked_Free_List< T, ACE_LOCK >::remove | ( | void | ) | [inline, virtual] |
Takes a element off the freelist and returns it. It creates <inc> new elements if the size is at or below the low water mark.
