public class Sequence extends Object implements Comparable<Sequence>
Represents a weighted sequence of outcomes.

  • Constructor Details

    • Sequence

      public Sequence()
      Initializes a new Sequence of outcomes.

    • Sequence

      public Sequence(Sequence s)
      Initializes a new Sequence of outcomes from an existing Sequence.
      Parameters:
      s - An existing Sequence used as input.

    • Sequence

      public Sequence(Sequence s, String outcome, double p)
      Initializes a new Sequence of outcomes from an existing Sequence.
      Parameters:
      s - An existing Sequence used as input.
      outcome - An extra outcome to add to s.
      p - A extra probability of the outcome.

    • Sequence

      public Sequence(List<String> outcomes)
      Initializes a new Sequence of outcomes from a list of outcomes. The probabilities for each outcome will be equally initialized to ONE.
      Parameters:
      outcomes - Several existing outcomes used as input.

  • Method Details

    • add

      public void add(String outcome, double p)
      Adds an outcome and probability to this sequence.
      Parameters:
