Interface AssessmentList

All Superinterfaces:
AutoCloseable, Closeable, OsidList, OsidList

Like all OsidLists , AssessmentList provides a means for accessing Assessment elements sequentially either one at a time or many at a time. Examples: 

while (al.hasNext()) {
     Assessment assessment = al.getNextAssessment();
}
or 
while (al.hasNext()) {
     Assessment[] assessments = al.hetNextAssessments(al.available());
}
