deserialise

public static QualityIndicator deserialise(java.util.Map pa)
                                    throws java.lang.IllegalArgumentException

This method guarantees that a PersistentObject can be deserialised properly from its own set of persistent attributes. It is a reverse of getPersistentAttributes()

Parameters:

pa - a HashMap of persistent attributes (created by {@link #getPersistentAttributes())

Throws:

java.lang.IllegalArgumentException
