class NondetWordAutom
[source: scala/util/automata/NondetWordAutom.scala]
abstract class NondetWordAutom[T <: AnyRef]
extends AnyRef
A nondeterministic automaton. States are integers, where 0 is always the only initial state. Transitions are represented in the delta function. Default transitions are transitions that are taken when no other transitions can be applied. All states are reachable. Accepting states are those for which the partial function 'finals' is defined.
Value Summary
abstract val default : Array[BitSet]
abstract val delta : Array[Map[T, BitSet]]
abstract val finals : Array[Int]
abstract val labels : Seq[T]
abstract val nstates : Int
Method Summary
final def containsFinal (Q : BitSet) : Boolean
returns true if the set of states contains at least one final state
final def finalTag (state : Int) : Int
returns tag of final state
final def isEmpty : Boolean
returns true if there are no accepting states
final def isFinal (state : Int) : Boolean
returns true if the state is final
def next (q : Int, a : T) : BitSet
returns a bitset with the next states for given state and label
def next (Q : BitSet, a : T) : BitSet
returns a bitset with the next states for given state and label
def nextDefault (Q : BitSet) : BitSet
override def toString : java.lang.String
Returns a string representation of the object.
