Constructor Summary

MMEPUnit(int forbiddenCardinality, java.util.Vector<UserAction> mmep)
This constructor creates the MMEPUnit object.

Method Summary

int	getMatchCount() This method returns the current match count of MMEP, i.e.
boolean	MMEPMatches(java.lang.String action, java.lang.String target) This method compare mmep with the input user action and target, to determine if this action and target pair match any mmep privileges.
void	startMatch() This method starts a new matching between user actions and this MMEP unit.

MMEPUnit

public MMEPUnit(int forbiddenCardinality,
                java.util.Vector<UserAction> mmep)

This constructor creates the MMEPUnit object.

Method Detail

getMatchCount

public int getMatchCount()

This method returns the current match count of MMEP, i.e. until now, how many MMEP have been matched by the user actions this MMEP Unit.

startMatch

public void startMatch()

This method starts a new matching between user actions and this MMEP unit.

MMEPMatches

public boolean MMEPMatches(java.lang.String action,
                           java.lang.String target)

This method compare mmep with the input user action and target, to determine if this action and target pair match any mmep privileges. Once matched, matchCount is increased by 1, and if matchCount reaches forbiddenCardinality, then this MMEP rule is broken by the user, true will be returned; otherwise, false will be returned. return true if this user action and target matches any one of the MMEP privilege and the forbeddenCardinality is reached; otherwise return false.

toString

public java.lang.String toString()

This method is to output all the MMEP action information as a String. This is for testing purposes.
