Classifier(java.lang.String c, java.lang.String a, java.lang.String n)

Method Summary

static int	createSharedClassifier(Classifier c, Agent[] ag) Create a unique instance of a classifier shared by several Agents so that the user has to modify only this classifier to affect the behaviour of all the Agents

Method Detail

createSharedClassifier

public static int createSharedClassifier(Classifier c,
                                         Agent[] ag)

Create a unique instance of a classifier shared by several Agents so that the user has to modify only this classifier to affect the behaviour of all the Agents

Parameters:

c -

ag -

Returns:

removeSharedClassifier

public static int removeSharedClassifier(Classifier c,
                                         Agent[] ag)

fromString

public static Classifier fromString(java.lang.String s,
                                    Template t)

Returns a Classifier object from a string "XXX->YYYY [cccc]" where X,Y = {0,1,#} XXX is the condition part, YYYY is the action part cccc is the name to put between square brackets (optional)

Parameters:

s - the String describing the classifier

Returns:

a Classifier if the String is correct, null otherwise

getBits
