Examples of ReadWriteSynchronizer

org.apache.commons.configuration2.sync.ReadWriteSynchronizer

A special implementation of {@code Synchronizer} based on the JDK's{@code ReentrantReadWriteLock} class.

This class manages a {@code ReadWriteLock} object internally. The methods ofthe {@code Synchronizer} interface are delegated to this lock. So this classbehaves in the same way as documented for {@code ReentrantReadWriteLock}.

Using this {@code Synchronizer} implementation is appropriate to makeconfiguration objects thread-safe. This means that multiple threads can read configuration data in parallel; if one thread wants to update the configuration, this happens with an exclusive lock.
