org.apache.giraph.partition

Interface ReusesObjectsPartition<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>

Type Parameters:

I - Vertex id

V - Vertex value

E - Edge value

All Superinterfaces:

GiraphConfigurationSettable<I,V,E>, ImmutableClassesGiraphConfigurable<I,V,E>, Iterable<Vertex<I,V,E>>, Partition<I,V,E>, org.apache.hadoop.io.Writable

All Known Implementing Classes:

ByteArrayPartition

public interface ReusesObjectsPartition<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>
extends Partition<I,V,E>

Empty interface to characterize Partition implementations that don't keep references to the Vertex objects they are passed. The Giraph infrastructure can exploit this characteristic by reusing Vertex objects.
