Operation
Operation.toString()
method. So an Operation
subclass can override this method and add additional debugging content. The default implementation does nothing so
one is not forced to provide an empty implementation.
It is a good practice always to call the super.toString(stringBuffer) when implementing this method to make sure
that the super class can inject content if needed.Copyright © 2016 Hazelcast, Inc.. All Rights Reserved.
