Questions tagged [readwritelock]

ReadWriteLock is a structure of the two locks. From these, one locks for reading (multiple threads can access, none can modify) and another for write access (only one thread can access and also modify at time).

In Java, ReadWriteLock is a very abstract interface which provides functionality to synchronize between multiple readers and one exclusive writer.

It just assumes some structure that contains two locks. Serious problems with this interface are unlikely. If you ask something about it, probably you mean ReentrantReadWriteLock, the implementation.
