public interface Container

extends Collection

A Container is a grouping of statements. A container can either be a Alternative, Bag, or Sequence. See 4.1 RDF Containers. Alternatives are unordered lists that do not allow duplicates. Bags are unordered lists that allow duplicates. Sequences are ordered lists that allows duplicates. Currently, this is just an extension of java.util.Collection that throws exceptions when inappropriate objects are used, for example non-ObjectNodes are added.
