java.lang.Object
  com.sun.mdm.index.decision.DecisionMaker

Direct Known Subclasses:

DefaultDecisionMaker

public abstract class DecisionMaker

extends java.lang.Object

Interface for logic that determines which records are potential duplicates and which record may be an assumed match.

Constructor Summary

DecisionMaker()

Method Summary

abstract float	getDuplicateThreshold() Return the potential duplicate threshold.
MasterControllerCore	getMasterController() Get the handle of the MC
abstract float	getMatchThreshold() Return the assumed match threshold.
abstract DecisionMakerResult	process(java.sql.Connection con, java.util.ArrayList list, SystemObject so) Given a list of ScoreElements, populate a DecisionMakerResult struct to indicate which records are potential duplicates and which record may be an assumed match.
void	setMasterController(MasterControllerCore mc) Allows a handle to the MC to be passed in
abstract void	setParameter(java.lang.String parameterName, java.lang.Object value) Parameters of the decision maker represented in the configuration XML file are set using this method.

Method Detail

getDuplicateThreshold

public abstract float getDuplicateThreshold()
                                     throws DecisionMakerException

Return the potential duplicate threshold. This is a minimum comparison score cutoff such that the MasterController will not send any ScoreElements to the decision maker process function with a score lower than this.

Returns:

duplicate threshold

Throws:

DecisionMakerException - an error occurred

getMasterController

public final MasterControllerCore getMasterController()

Get the handle of the MC

Returns:

master controller handle

getMatchThreshold

public abstract float getMatchThreshold()
                                 throws DecisionMakerException

Return the assumed match threshold. This is a minimum comparison score cutoff such that the MasterController will consider any records as Assumed Matches.

Returns:

assumed match threshold

Throws:

DecisionMakerException - an error occured

process

public abstract DecisionMakerResult process(java.sql.Connection con,
                                            java.util.ArrayList list,
                                            SystemObject so)
                                     throws DecisionMakerException

Given a list of ScoreElements, populate a DecisionMakerResult struct to indicate which records are potential duplicates and which record may be an assumed match.

Parameters:

con - database connection

list - input list of ScoreElements

so - system object being evaluated

Returns:

array of decision maker results

Throws:

DecisionMakerException - an error occurred

setMasterController

public final void setMasterController(MasterControllerCore mc)

Allows a handle to the MC to be passed in

Parameters:

mc - master controller

setParameter

public abstract void setParameter(java.lang.String parameterName,
                                  java.lang.Object value)
                           throws DecisionMakerException

Parameters of the decision maker represented in the configuration XML file are set using this method.

Parameters:

parameterName - parameter

value - parameter value

Throws:

DecisionMakerException - An error occurred
