# AbstractCache
## `autogen.cache.AbstractCache`
Bases: `Protocol`
This protocol defines the basic interface for cache operations. Implementing classes should provide concrete implementations for these methods to handle caching mechanisms.
### `get`
```
get(key, default=None)
```
Retrieve an item from the cache.
| PARAMETER | DESCRIPTION |
| --- | --- |
| `key` | The key identifying the item in the cache.
**TYPE:**`str` |
| `default` | The default value to return if the key is not found. Defaults to None.
**TYPE:**`optional`**DEFAULT:**`None` |
| RETURNS | DESCRIPTION |
| --- | --- |
| `Any | None` | The value associated with the key if found, else the default value. |

def get(self, key: str, default: Any | None = None) -> Any | None:
"""Retrieve an item from the cache.
Args:
key (str): The key identifying the item in the cache.
default (optional): The default value to return if the key is not found.
Defaults to None.
Returns:
The value associated with the key if found, else the default value.

### `set`
```
set(key, value)
```
Set an item in the cache.
| PARAMETER | DESCRIPTION |
| --- | --- |
| `key` | The key under which the item is to be stored.
**TYPE:**`str` |
| `value` | The value to be stored in the cache.
**TYPE:**`Any` |

### `close`
```
close()
```
Close the cache. Perform any necessary cleanup, such as closing network connections or releasing resources.
