The BasicLockable requirements describe the minimal characteristics of types that provide exclusive blocking semantics for execution agents (i.e. threads).
For type L
to be BasicLockable, the following conditions have to be satisfied for an object m
of type L
:
Expression | Requires | Effects |
---|---|---|
m.lock() | Blocks until a lock can be obtained for the current execution agent (thread, process, task). If an exception is thrown, no lock is obtained. | |
m.unlock() | The current execution agent should hold the lock m . | Releases the lock held by the execution agent. Throws no exceptions. |
