< cpp‎ | concept

The `Lockable` concept extends the `BasicLockable` concept to include attempted locking.

### [edit] Requirements

- `BasicLockable`

For type `L` to be `Lockable`, it must meet the above condition as well as the following:

Expression | Effects | Return value
--- | --- | ---
m.try_lock() | Attempts to acquire the lock for the current execution agent without blocking. If an exception is thrown, no lock is obtained. | true if the lock was acquired, false otherwise
