Is there a way to prevent a ProcessInstance from not moving on to the next state despite it being signalled?

For example, I call the signal method on a ProcessInstance but can I write code inside any of the ActionHandlers to prevent the ProcessInstance from moving to the next state & continue to stay at the same state it was at.
In another words, I am trying to override the signal. Is it possible?

Thanks
