| Interface | Description |
|---|---|
| Aggregator<M extends org.apache.hadoop.io.Writable,VERTEX extends Vertex<?,?,?>> |
Aggregators are a mechanism for global communication, monitoring, and data.
|
| VertexInterface<V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable,M extends org.apache.hadoop.io.Writable> |
The vertex interface.
|
| Class | Description |
|---|---|
| AbsDiffAggregator |
A absolute difference aggregator, it collects values before the compute and
after the compute, then calculates the difference and globally accumulates
(sums them up) them.
|
| AbstractAggregator<M extends org.apache.hadoop.io.Writable,VERTEX extends Vertex<?,?,M>> |
Abstract base case of an aggregator.
|
| AggregationRunner<V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable,M extends org.apache.hadoop.io.Writable> |
Runner class to do the tasks that need to be done if aggregation was
configured.
|
| AverageAggregator |
Averages the result of the
AbsDiffAggregator. |
| Edge<VERTEX_ID extends org.apache.hadoop.io.Writable,EDGE_VALUE_TYPE extends org.apache.hadoop.io.Writable> |
The edge class
|
| GraphJob | |
| GraphJobMessage |
A message that is either MapWritable (for meta communication purposes) or a
real message (vertex ID and value).
|
| GraphJobRunner<V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable,M extends org.apache.hadoop.io.Writable> |
Fully generic graph job runner.
|
| MaxAggregator | |
| MinAggregator | |
| SumAggregator |
Sums all vertex values globally.
|
| Vertex<V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable,M extends org.apache.hadoop.io.Writable> | |
| VertexInputReader<KEYIN extends org.apache.hadoop.io.Writable,VALUEIN extends org.apache.hadoop.io.Writable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable,M extends org.apache.hadoop.io.Writable> |
A reader to read Hama's input files and parses a vertex out of it.
