clear typeof(this) clear(): Recycles all items in the pool.
deleteItem void deleteItem(Item item): Deletes item and sets it to null.
fill_ typeof(this) fill_(size_t num, Item new_item): Ensures that the pool contains at least the specified number of items. Useful to pre-allocate a pool of a certain size.
getItemIndex size_t getItemIndex(Item item): Gets the object pool index of item.
get_ Item get_(Item new_item): Takes an idle item from the pool or creates a new one if all items are busy or the pool is empty.
isBusy bool isBusy(Item item): Checks if item is currently busy.
isNull bool isNull(Item item): Checks if item is null.
isSame bool isSame(Item a, Item b): Checks a and b for identity.
is_limited bool is_limited()
length size_t length(): Returns the number of items in pool.
limit size_t limit(): Returns the limit of number of items in pool or unlimited if currently unlimited.
num_busy size_t num_busy(): Returns the number of busy items in pool.
num_idle size_t num_idle(): Returns the number of idle items in pool.
opIndex_ Item opIndex_(size_t n): Obtains the n-th pool item. n must be less than the value returned by length().
recycle_ void recycle_(Item item_in): Puts item back to the pool.
resetItem void resetItem(Item item): Resets item.
setItemIndex void setItemIndex(Item item, size_t n): Sets the object pool index to item.
setLimit size_t setLimit(size_t limit): Sets the limit of number of items in pool or disables limitation for limit = unlimited. When limiting the pool, any excess idle items are reset and deleted.
truncate void truncate(size_t remove): Removes idle items from the pool. Excess idle items are reset and deleted.
