## de.grogra.numeric
Interface Monitor

    public interface Monitor

This class represents a set of monitor functions. Each monitor function gi(t,y) calculates a single value for a node (t,y). Multiple monitor functions are calculated by a single function g(t,y) at once. When the return value of one of the gi changes its sign, rootfinding methods are used to determine the exact time t of the first event (when gi(t,y) is 0). Then, for each event i that triggered, the function handleEvent(i,t,y) is called. The event handler will return true if integration should stop. Multiple events triggered, integration will stop if at least one of the gi returned true.
