Method Detail

nextStateValue

public double nextStateValue(double actualState,
                             double value)
Description copied from interface: StateDecider
Return the next state. The result may depend on the given actualState and the current value but is allowed to depend on anything else. Be sure to have isCacheable() return a correct result then.
Specified by:
nextStateValue in interface StateDecider
Following copied from interface: de.jaetzold.util.StateDecider

isCacheable

public boolean isCacheable()
Description copied from interface: StateDecider
Tells whether this instance will in the future produce the same state for the same value argument, independent of the actualState. This can be false first and then true at a later time, but it is not legal to return false here after a return of true in the past, because the true answer before was wrong then.
Specified by:
isCacheable in interface StateDecider
Following copied from interface: de.jaetzold.util.StateDecider
Returns:
true if this instance guarantees, that any further call to nextStateValue() with the same value-argument returns the same state
