Detailed Description
class Dune::lru< Key, Tp, Traits >
LRU Cache Container.
Implementation of an LRU (least recently used) cache container. This implementation follows the approach presented in http://aim.adc.rmit.edu.au/phd/sgreuter/papers/graphite2003.pdf
Member Function Documentation
◆ back() [1/2]
|
inline |
Returns a read/write reference to the data of the least recently used entry.
◆ back() [2/2]
|
inline |
Returns a read-only (constant) reference to the data of the least recently used entry.
◆ find() [1/2]
|
inline |
Finds the element whose key is k.
- Returns
- iterator
◆ find() [2/2]
|
inline |
Finds the element whose key is k.
- Returns
- const_iterator
◆ front() [1/2]
|
inline |
Returns a read/write reference to the data of the most recently used entry.
◆ front() [2/2]
|
inline |
Returns a read-only (constant) reference to the data of the most recently used entry.
◆ insert() [1/2]
|
inline |
mark data associated with key as most recent
- Returns
- reference of stored data
References Dune::lru< Key, Tp, Traits >::touch().
◆ insert() [2/2]
|
inline |
Insert a value into the container.
Stores value under key and marks it as most recent. If this key is already present, the associated data is replaced.
- Parameters
-
key associated with data data to store
- Returns
- reference of stored data
◆ resize()
|
inline |
ensure a maximum size of the container
If new_size is smaller than size the oldest elements are dropped. Otherwise nothing happens.
References Dune::lru< Key, Tp, Traits >::pop_back(), and Dune::lru< Key, Tp, Traits >::size().
◆ touch()
|
inline |
mark data associated with key as most recent
- Returns
- reference of stored data
