Description copied from class: AbstractComputation

Must be defined by user to do computation on a single Vertex.

Specified by:

compute in interface Computation<org.apache.hadoop.io.LongWritable,org.apache.hadoop.io.IntWritable,org.apache.hadoop.io.FloatWritable,VerifyMessage.VerifiableMessage,VerifyMessage.VerifiableMessage>

Specified by:

compute in class AbstractComputation<org.apache.hadoop.io.LongWritable,org.apache.hadoop.io.IntWritable,org.apache.hadoop.io.FloatWritable,VerifyMessage.VerifiableMessage,VerifyMessage.VerifiableMessage>

Parameters:

vertex - Vertex

messages - Messages that were sent to this vertex in the previous superstep. Each message is only guaranteed to have a life expectancy as long as next() is not called.

Throws:

IOException
