 # API
 
 - `acquire`: Acquires the lock, returns _true_ if the operation was successful otherwise the return is _false_.
 - `release`: Releases the lock, returns _true_ if the operation was successful otherwise the return is _false_.
-- `destroy`: allows manually destruction of the lock. Internally release the lock and perform a cleanup operation. It's the same process used by the `__destruct` magic method.
 - `id`: returns the lock id.
 - `getPath`: returns the lock path
