I- Vertex id
E- Edge value
public interface ReuseObjectsOutEdges<I extends org.apache.hadoop.io.WritableComparable,E extends org.apache.hadoop.io.Writable> extends OutEdges<I,E>
OutEdgesimplementations that don't keep references to the Edge (or id and value) objects they are passed. The Giraph infrastructure can exploit this characteristic by reusing Edge objects.
