Method Details

getUsersToPropagate

public java.util.stream.Stream<U> getUsersToPropagate(PropagatedInformation information, UserState<U> originUser, Data<U,I,P> data)

Description copied from interface: PropagationMechanism

Selects the users to which propagate a single piece of information.

Specified by:

getUsersToPropagate in interface PropagationMechanism<U extends java.io.Serializable,I extends java.io.Serializable,P>

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.

dependsOnInformationPiece

public boolean dependsOnInformationPiece()

Description copied from interface: PropagationMechanism

This indicates whether the selection of the users depends or not on the information piece which we want to propagate.

Specified by:

dependsOnInformationPiece in interface PropagationMechanism<U extends java.io.Serializable,I extends java.io.Serializable,P>

Returns:

true if it depends on the information piece, false if it does not.
