xades4j.xml.unmarshalling.QualifyingPropertiesDataCollector |
Passed to a QualifyingPropertiesUnmarshaller
to collect the property
data obejcts. This is used instead of a collection that is returned by the unmarshaller
because it allows controlling the number of occurrences of each property.
All the methods will throw PropertyTargetException
if an attempt is made
to add a repeated instance or an instance of a type that was already added and
should occur only once. Also, NullPointerException
is thrown if an attempt
is made to add a null
reference.
