# ExtObjectContainer.purge Method ()

unloads all clean indices from memory and frees unused objects.

void purge();

#### Remarks

unloads all clean indices from memory and frees unused objects.
Call commit() and purge() consecutively to achieve the best result possible. This method can have a negative impact on performance since indices will have to be reread before further inserts, updates or queries can take place.
