Class GradoopIdSet

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractSet<GradoopId>

org.gradoop.common.model.impl.id.GradoopIdSet

All Implemented Interfaces:

Serializable, Iterable<GradoopId>, Collection<GradoopId>, Set<GradoopId>, org.apache.flink.core.io.IOReadableWritable, org.apache.flink.types.Value

public class GradoopIdSet
extends AbstractSet<GradoopId>
implements org.apache.flink.types.Value

Represents a set of GradoopId instances, ignoring any duplicates. Note that by implementing List Flink uses the Kryo serializer for (de-)serializing the list.
