Class EventSequence

java.lang.Object
com.topologi.diffx.sequence.EventSequence
public final class EventSequence extends Object
A sequence of events used for the Diff-X algorithm.

This class wraps a list of DiffXEvents and provide method to access and modify the content of the list using strongly typed methods.

    • addEvent

      public void addEvent(DiffXEvent e)
      Adds an event to this sequence.
      Parameters:
      e - The event to be added.

    • addEvent

      public void addEvent(int i, DiffXEvent e)
      Inserts an event to this sequence at the specified position.
      Parameters:

      Replaces an event of this sequence at the specified position.
      Parameters:
      index - The 0-based index of the position.
      e - The event to be inserted.
      Returns:
      The event at the previous position.

    • removeEvent

      public DiffXEvent removeEvent(int index)
      Removes an event from this sequence at the specified position.
