package org.apache.commons.configuration2.sync;

 An implementation of the Synchronizer interface which does not perform any synchronization. 
 This class is the option of choice for applications that do not access configuration concurrently. All methods required by the Synchronizer interface are just empty dummies. Therefore, this class does not have any synchronization overhead. Of course, configurations using this Synchronizer implementation are not thread-safe! 

Implementation note: This class is an enumeration because only a single
instance needs to exist. This instance can be shared between arbitrary
configurations.

Since:
