Modifier and Type	Method and Description
protected String	constructClusteredJobID(Partition partition) Returns the ID for the clustered job corresponding to a partition.
String	description() Returns a textual description of the transfer implementation.
void	determineInputOutputFiles(AggregatedJob job, List<Job> orderedJobs) Determine the input and output files of the job on the basis of the order of the constituent jobs in the AggregatedJob.
protected String	getLogicalNameForJobs(List<Job> jobs) Returns null as for label based clustering we dont want the transformation name to be considered for constructing the name of the clustered jobs
List	order(Partition p) Returns the nodes in the partition as a List in the topologically sorted order.

Method Detail

description

public String description()

Returns a textual description of the transfer implementation.

Returns:

a short textual description

order

public List order(Partition p)
           throws ClustererException

Returns the nodes in the partition as a List in the topologically sorted order.

Specified by:

order in class Abstract

Parameters:

p - the partition whose nodes have to be ordered.

Returns:

an ordered List of String objects that are the ID's of the nodes.

Throws:

ClustererException - in case of error.

determineInputOutputFiles

public void determineInputOutputFiles(AggregatedJob job,
                             List<Job> orderedJobs)

Determine the input and output files of the job on the basis of the order of the constituent jobs in the AggregatedJob. The input and output files are determined on the basis of topologically sorted order of the constituent jobs.

Specified by:

determineInputOutputFiles in class Abstract

Parameters:

job - the AggregatedJob

orderedJobs - the List of Jobs that is ordered as determined by the clustererr

Throws:

ClustererException - in case of error.

getLogicalNameForJobs

protected String getLogicalNameForJobs(List<Job> jobs)

Returns null as for label based clustering we dont want the transformation name to be considered for constructing the name of the clustered jobs

Overrides:

getLogicalNameForJobs in class Abstract

Parameters:

jobs - List of jobs

Returns:

name

constructClusteredJobID

protected String constructClusteredJobID(Partition partition)

Returns the ID for the clustered job corresponding to a partition.

Overrides:

constructClusteredJobID in class Abstract

Parameters:

partition - the partition.

Returns:

the ID of the clustered job
