Input
string $key key
Output
mixed|NULL  
Throws
throws InvalidArgumentException

line 192

offsetSet

public void offsetSet (string $key, mixed $data)

Dependencies are: priority => (int) priority expire => (timestamp) expiration refresh => (bool) use sliding expiration? tags => (array) tags files => (array|string) file names items => (array|string) cache items consts => (array|string) cache items

Input
string $key key
mixed $data
$dependencies
Output
void  
Throws
throws InvalidArgumentException
