Interface QualifierList

All Superinterfaces:
AutoCloseable, Closeable, OsidList, OsidList
public interface QualifierList extends OsidList

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

while (ql.hasNext()) {
     Qualifier qualifier = ql.getNextQualifier();
}
or 
while (ql.hasNext()) {
     Qualifier[] qualifiers = ql.hetNextQualifiers(ql.available());
}
