Method Detail

clearState

public void clearState()

If the concrete class decides not to provide the implementation of this method, then it's OK. Some of the examples where we may decide to not provide the implementation is the connection state. Irrespective of the call to clearState, the connection state will be showing the currect state of the connection. NOTE: This method is only used to clear the Monitored Attribute state, not the real state of the system itself.
