Step(Int32, Int32)

Returns the state obtained by reading the given char from the given state. Returns -1 if not obtaining any such state. (If the original Automaton had no dead states, -1 is returned here if and only if a dead state is entered in an equivalent automaton with a total transition function.)

Declaration

public int Step(int state, int c)

Parameters

Type	Name	Description
System.Int32	state
System.Int32	c

Returns

Type	Description
System.Int32

ToString()

Returns a string representation of this automaton.

Declaration

public override string ToString()

Returns

Type	Description
System.String

Overrides

System.Object.ToString()
