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.
- Overrides:
isCacheable
in class LinkedStateDecider
- 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
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.- Following copied from interface:
