All Implemented Interfaces:

IDecompositionListener, IGraphPartitionExtension

public abstract class GraphPartitionExtensionAdapter
extends Object
implements IGraphPartitionExtension

GraphPartitionExtensionAdapter provides an empty implementation of IGraphPartitionExtension.

The only real functionality is contained in method IGraphPartitionExtension.preparePartition(PathSearchConfiguration, GraphPartition) which stores the given PathSearchConfiguration and GraphPartition in properties.

Method Detail

cleanup

public void cleanup()

Description copied from interface: IGraphPartitionExtension

Cleans up the extension from the last partitioning with the current configuration and GraphPartition.

Specified by:

cleanup in interface IGraphPartitionExtension

getConfiguration

protected PathSearchConfiguration getConfiguration()

Gets the configuration of the PathSearch passed to IGraphPartitionExtension.preparePartition(PathSearchConfiguration, GraphPartition).

Returns:

the configuration of the PathSearch passed to IGraphPartitionExtension.preparePartition(PathSearchConfiguration, GraphPartition) or null if said method has not been called yet or this instance has been cleaned up

getGraphPartition

protected GraphPartition getGraphPartition()

Gets the GraphPartition passed to IGraphPartitionExtension.preparePartition(PathSearchConfiguration, GraphPartition).

Returns:

the GraphPartition passed to IGraphPartitionExtension.preparePartition(PathSearchConfiguration, GraphPartition) or null if said method has not been called yet or this instance has been cleaned up

onCellCreated

public void onCellCreated(PartitionCell createdCell)

Description copied from interface: IDecompositionListener

Callback after the new given PartitionCell has been created.

Specified by:

onCellCreated in interface IDecompositionListener

Parameters:

createdCell - the newly created PartitionCell

onCellFinalized

public void onCellFinalized(PartitionCell finalizedCell)

Description copied from interface: IDecompositionListener

Callback after the given PartitionCell has been finalized and won't be further subdivided.

Specified by:

onCellFinalized in interface IDecompositionListener

Parameters:

finalizedCell - the cell that has been finalized

onCellSubdivided

public void onCellSubdivided(PartitionCell cell,
                             List<Object> subCells)

Description copied from interface: IDecompositionListener

Callback after the given PartitionCell has been subdivided into several sub-cells.

IDecompositionListener may not modify the list of sub-cells.

Specified by:

onCellSubdivided in interface IDecompositionListener

Parameters:

cell - the cell that has been subdivided

subCells - the sub-cells resulting from the subdivision of the given PartitionCell

preparePartition

public void preparePartition(PathSearchConfiguration configuration,
                             GraphPartition graphPartition)

Stores the given PathSearchConfiguration and GraphPartition such that they are accessible through Configuration and GraphPartition, respectively.

Specified by:

preparePartition in interface IGraphPartitionExtension

Parameters:

configuration - the configuration used for the path search

graphPartition - the graph partition that uses this extension
