Interface Summary

Interface	Description
MappingStore<I extends org.apache.hadoop.io.WritableComparable,B extends org.apache.hadoop.io.Writable>	MappingStore used to store the vertexId - target map supplied by user Methods implemented in this class need to be thread safe
MappingStoreOps<I extends org.apache.hadoop.io.WritableComparable,B extends org.apache.hadoop.io.Writable>	Interface of operations that can be done on mapping store once it is fully loaded

Class Summary

Class	Description
AbstractLongByteOps	Implementation of basic methods in MappingStoreOps
DefaultEmbeddedLongByteOps	MappingStoreOps implementation used to embed target information into vertex id.
DefaultLongByteOps	MappingStoreOps implementation which reads partition information from map
LongByteMappingStore	An implementation of MappingStore<LongWritable, ByteWritable> Methods implemented here are thread safe by default because it is guaranteed that each entry is written to only once.
MappingEntry<I extends org.apache.hadoop.io.WritableComparable,B extends org.apache.hadoop.io.Writable>	An entry in MappingStore
