Class DatabaseWeightedTallyAlgorithm<ENTRY,WEIGHT,DAO extends InsertDao<WEIGHT> & GetDao<WEIGHT>,RESPONSE>

java.lang.Object

net.ashwork.upvote.database.domain.algorithm.DatabaseWeightedTallyAlgorithm<ENTRY,WEIGHT,DAO,RESPONSE>

Type Parameters:

ENTRY - the type of the entry data

WEIGHT - the type of the weights on the data

RESPONSE - the type of the response to the tally

All Implemented Interfaces:

net.ashwork.upvote.domain.algorithm.TallyAlgorithm<ENTRY,RESPONSE>, net.ashwork.upvote.domain.algorithm.WeightedTallyAlgorithm<ENTRY,WEIGHT,RESPONSE>

public class DatabaseWeightedTallyAlgorithm<ENTRY,WEIGHT,DAO extends InsertDao<WEIGHT> & GetDao<WEIGHT>,RESPONSE>
extends java.lang.Object
implements net.ashwork.upvote.domain.algorithm.WeightedTallyAlgorithm<ENTRY,WEIGHT,RESPONSE>

An algorithm used to tally all or a specific subset of entries with some weighted association and return some response about the tallied results. The result of the supplied algorithm will then be persisted to some table containing the weights.

Since:

1.0.0

A simple constructor.

Parameters:

dao - the domain access object of the table

persistAllSuccess - a supplied response for successful insertions of the weights

throwingError - a function to convert a thrown throwable to a response

algorithm - an algorithm to calculate the new weights of the tally
