```
Value computeIfAbsent(Key key,
                      ISerializableThrowingFunction<? super Key,? extends Value> loader)
               throws IOException
```
    Gets the value for the given key. When the value exists already, it will be returned. If the value does not exist yet, it will be loaded using the given loader.
    
    Parameters:
    
    key - The key for which to get the value.
    
    loader - The loader to use if the value does not exist or is stale.
    
    Returns:
    
    The associated value, either from the store if still fresh, or obtained from the bound loader.
    
    Throws:
    
    IOException - If the loader throws an exception.
  - getIfPresent
```
Value getIfPresent(Key key)
```
    Gets the value associated with the given key. Returns null if no value exists yet.
    
    Parameters:
    
    key - The key to get the value for.
    
    Returns:
    
    The associated value, if present, or null if no value exists.
  - remove
```
void remove(Key key)
```
    Removes the value at the given key, if present. Does nothing if no value exists yet.
    
    Parameters:
    
    key - The key to remove the value for.
  - removeAndGetIfPresent
```
Value removeAndGetIfPresent(Key key)
```
    Removes the value at the given key, if present, and returns the removed value. Does nothing if no value exists yet. The value returned by this method will NOT be closed if it implements AutoCloseable.
    
    Parameters:
    
    key - The key to remove the value for.
    
    Returns:
    
    The removed value, if present, or null if no value exists.
