public interface PropagationMechanism<U extends java.io.Serializable,​I extends java.io.Serializable,​P>
Mechanism for selecting the set of users towards whom each user in the network propagates his/her information pieces.

  • Method Summary

    Modifier and Type Method Description
    boolean dependsOnInformationPiece()
    This indicates whether the selection of the users depends or not on the information piece which we want to propagate.
    java.util.stream.Stream<U> getUsersToPropagate​(PropagatedInformation information, UserState<U> originUser, Data<U,​I,​P> data)
    Selects the users to which propagate a single piece of information.
    default void resetSelections​(Data<U,​I,​P> data)
    It resets the selections that this mechanism did in past iterations.

  • Method Details

    • getUsersToPropagate

      java.util.stream.Stream<U> getUsersToPropagate​(PropagatedInformation information, UserState<U> originUser, Data<U,​I,​P> data)
      Selects the users to which propagate a single piece of information.
      Parameters:
      information - the information piece to propagate.
      originUser - the user who propagates the information piece.
      data - the complete data for the simulation.
      Returns:
      the stream of users to which propagate the single piece of information.

    • resetSelections

      default void resetSelections​(Data<U,​I,​P> data)
      It resets the selections that this mechanism did in past iterations.
      Parameters:
      data - the data.

    • dependsOnInformationPiece

      boolean dependsOnInformationPiece()
      This indicates whether the selection of the users depends or not on the information piece which we want to propagate.
      Returns:
      true if it depends on the information piece, false if it does not.
