Detailed Description

Generic container type.

This is the base container type that contains values common to all container types.

Todo:
Linking and unlinking container objects is typically expensive, as it involves a malloc()/free() of a small object which is very inefficient. To optimize this, we can allocate larger arrays of container nodes when we run out of them, and then manage our own freelist. This will be more efficient as we can do the freelist management while we hold the lock (that we need anyway).
Examples

Field Documentation

◆ cmp_fn

ao2_callback_fn* cmp_fn

Container traversal matching function for ao2_find.

Definition at line 276 of file astobj2_container_private.h.

Referenced by __ao2_container_alloc_list(), hash_ao2_alloc_empty_clone(), hash_ao2_container_init(), rb_ao2_alloc_empty_clone(), and rb_ao2_container_init().

◆ destroying

unsigned int destroying

TRUE if the container is being destroyed.

Note
The destruction traversal should override any requested search order to do the most efficient order for destruction.
There should not be any empty nodes in the container during destruction. If there are then an error needs to be issued about container node reference leaks.

◆ elements

int elements

Number of elements in the container.

◆ options

uint32_t options
