StateLocalInputSUL (LearnLib 0.18.0 API)

Type Parameters:

I - input symbol type

O - output symbol type

All Superinterfaces:

SUL<I,O>

All Known Implementing Classes:

CounterStateLocalInputSUL, StateLocalInputMealySimulatorSUL, StateLocalInputSULCache, ThreadSafeStateLocalInputSULCache
```
public interface StateLocalInputSUL<I,O>
extends SUL<I,O>
```
A System Under Learning (SUL) which can additionally report the inputs that the SUL can process in its current state, i.e. inputs that will not trigger a SULException when used in the next invocation of the SUL.step(Object) method return an otherwise "undefined" behavior.

- Method Detail
  - currentlyEnabledInputs
```
Collection<I> currentlyEnabledInputs()
```
    Returns the enabled symbols for the current state of the SUL.
    
    Returns:
    
    the currently enabled inputs
    
    Throws:
    
    SULException - if the SUL cannot provide information about the currently enabled inputs
  - fork
```
default StateLocalInputSUL<I,O> fork()
```
    Description copied from interface: SUL
    
    Forks this SUL, if possible. The fork of a SUL is a copy which behaves exactly the same as this SUL. This method should always return a reseted SUL, regardless of whether this call is made between a call to SUL.pre() and SUL.post().
    If SUL.canFork() returns true, this method must return a non-null object, which should behave exactly like this SUL (in particular, it must be forkable as well). Otherwise, a UnsupportedOperationException must be thrown.
    Implementation note: if resetting a SUL changes the internal state of this object in a non-trivial way (e.g., incrementing a counter to ensure independent sessions), care must be taken that forks of this SUL manipulate the same internal state.
    
    Specified by:
    
    fork in interface SUL<I,O>
    
    Returns:
    
    a fork of this SUL.
