POOL FACTORY HOW TO

concurrency when creating and releasing pool from/to the factory.ДЄ pool factory can be given different policy during creation to make it behave differently.callback to be called when memory allocation inside a pool fails (the default implementation will throw PJ_NO_MEMORY_EXCEPTION exception).how memory block is allocated and deallocated (the default implementation allocates and deallocate memory by calling malloc() and free()).

POOL FACTORY HOW TO

release_pool(): release memory pool back to factory.ДЄ pool factory only defines functions to create and release pool and how to manage pools, but the rest of the functionalities are controlled by policy.create_pool(): create a new memory pool.policy: the memory pool factory policy.The pool factory defines the following interface: Application can define its own strategy by creating it's own pool factory implementation, and this strategy can be used even by existing library without recompilation. The pool factory interface declared in PJLIB is designed to be extensible. Pj_pool_factory_dump ( pj_pool_factory *pf, pj_bool_t detail) Pj_pool_init_int ( pj_pool_t *pool, const char *name, pj_size_t increment_size, pj_pool_callback *callback) Pj_pool_create_int ( pj_pool_factory *factory, const char *name, pj_size_t initial_size, pj_size_t increment_size, pj_pool_callback *callback) Pj_pool_factory_get_default_policy (void) One sample implementation, pj_caching_pool, can be set to keep the pools released by application for future use as long as the total memory is below the limit. A factory not only provides generic interface functions to create and release pool, but also provides strategy to manage the life time of pools. A pool object must be created through a factory.
