  org.griphyn.cPlanner.partitioner.ClustererCallback

All Implemented Interfaces:

Callback

public class ClustererCallback
extends Object
implements Callback

A Callback implementation that passes the partitions detected during the partitioning of the worflow to a Clusterer for clustering. The clusterer is passed off to the callback during the callback initialization.

Method Detail

initialize

public void initialize(PegasusProperties properties,
                       Clusterer clusterer)

Initializes the callback.

Parameters:

properties - the properties passed to the planner.

clusterer - the clusterer that has to be called out, in the callback methods.

cbPartition

public void cbPartition(Partition p)

Callback for when a partitioner determines that partition has been constructed. The partition is passed off to the clusterer that the callback has been initialized with.

Specified by:

cbPartition in interface Callback

Parameters:

p - the constructed partition.

Throws:

RuntimeException - in case of callback not being initialized, or a ClustererException being thrown during the Clusterer operation.

cbParents

public void cbParents(String child,
                      List parents)

Callback for when a partitioner determines the relations between partitions that it has previously constructed.

Specified by:

cbParents in interface Callback

Parameters:

child - the id of a partition.

parents - the list of String objects that contain the id's of the parents of the partition.

Throws:

RuntimeException - in case of callback not being initialized, or a ClustererException being thrown during the Clusterer operation.

cbDone

public void cbDone()

Callback for the partitioner to signal that it is done with the processing.

Specified by:

cbDone in interface Callback
