Lock (Glazed Lists)

All Known Implementing Classes:

J2SE14ReadWriteLock.ReadLock, J2SE14ReadWriteLock.WriteLock
```
public interface Lock
```
A lock is a tool for controlling access to a shared resource by multiple threads.
This interface is a back-port of the Lock class that first appeared in J2SE 1.5. Due to a requirement for sophisticated concurrency, this interface has been back-ported for use in J2SE 1.4 (and greater). It shares similar method signatures to be consistent with the J2SE 1.5 API.
