Class TimestampOrderedSelectionMechanism<U extends java.io.Serializable,I extends java.io.Serializable,P>

java.lang.Object

es.uam.eps.ir.relison.diffusion.selections.AbstractSelectionMechanism<U,I,P>

es.uam.eps.ir.relison.diffusion.selections.CountSelectionMechanism<U,I,P>

es.uam.eps.ir.relison.diffusion.selections.TimestampOrderedSelectionMechanism<U,I,P>

Type Parameters:

U - the type of the users.

I - the type of the information pieces.

P - the type of the features.

All Implemented Interfaces:

SelectionMechanism<U,I,P>

public class TimestampOrderedSelectionMechanism<U extends java.io.Serializable,I extends java.io.Serializable,P>
extends CountSelectionMechanism<U,I,P>

Selection mechanism that takes into account the real timestamp of the information pieces to propagate the information owned by the user. Instead of randomly selecting a fixed number of information pieces, this mechanism selects the oldest available information.

Method Details

getOwnInformation

protected java.util.List<PropagatedInformation> getOwnInformation(UserState<U> user, Data<U,I,P> data, SimulationState<U,I,P> state, int numIter, java.lang.Long timestamp)

Description copied from class: AbstractSelectionMechanism

Obtains the list of own information pieces to repropagate.

Overrides:

getOwnInformation in class CountSelectionMechanism<U extends java.io.Serializable,I extends java.io.Serializable,P>

Parameters:

user - the user to analyze.

data - the full data.

state - current simulation state.

numIter - the iteration number.

timestamp - the timestamp for the current simulation.

Returns:

a selection of the own information pieces to be propagated.
