Examples of org.apache.jena.security.utils.CollectionGraph

org.apache.jena.security.utils.CollectionGraph
A simple graph implementaiton that wraps a colleciton of triples. This is intended to be used in places where a graph is required but iteration is the only expected operation. All graph operations are supported but many are not efficient and will be slow on large collections. In these cases a memory based graph may be more efficient.
