Constructor Detail

GraphPartitionExtensionAdapter

public GraphPartitionExtensionAdapter()

Creates a new instance of GraphPartitionExtensionAdapter.

Method Detail

getGraphPartition

protected GraphPartition getGraphPartition()

Returns the GraphPartition passed to GraphPartitionExtension.preparePartition(PathSearchConfiguration, GraphPartition).

Returns:

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

getConfiguration

protected PathSearchConfiguration getConfiguration()

Returns the configuration of the PathSearch passed to GraphPartitionExtension.preparePartition(PathSearchConfiguration, GraphPartition).

Returns:

the configuration of the PathSearch passed to GraphPartitionExtension.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: DynamicDecomposition.Listener

Callback after the new given PartitionCell has been created.

Specified by:

onCellCreated in interface DynamicDecomposition.Listener

Parameters:

createdCell - the newly created PartitionCell

onCellSubdivided

public void onCellSubdivided(PartitionCell cell,
                             java.util.List subCells)

Description copied from interface: DynamicDecomposition.Listener

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

DynamicDecomposition.Listener may not modify the list of sub-cells.

Specified by:

onCellSubdivided in interface DynamicDecomposition.Listener

Parameters:

cell - the cell that has been subdivided

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

onCellFinalized

public void onCellFinalized(PartitionCell finalizedCell)

Description copied from interface: DynamicDecomposition.Listener

Callback after the given PartitionCell has been finalized.

Before the cell may be further subdivided, it has to be unlocked again.

Specified by:

onCellFinalized in interface DynamicDecomposition.Listener

Parameters:

finalizedCell - the cell that has been finalized

onCellUnlocked

public void onCellUnlocked(PartitionCell unlockedCell)

Description copied from interface: DynamicDecomposition.Listener

Callback after the given PartitionCell has been unlocked.

The cell had previously be finalized but has been unlocked again and may be subdivided in the future.

Specified by:

onCellUnlocked in interface DynamicDecomposition.Listener

Parameters:

unlockedCell - the cell that has been unlocked

preparePartition

public void preparePartition(PathSearchConfiguration configuration,
                             GraphPartition graphPartition)

Stores the given PathSearchConfiguration and GraphPartition such that they are accessible through getConfiguration() and getGraphPartition(), respectively.

Specified by:

preparePartition in interface GraphPartitionExtension

Parameters:

configuration - the configuration used for the path search

graphPartition - the graph partition that uses this extension

cleanup

public void cleanup()

Description copied from interface: GraphPartitionExtension

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

Specified by:

cleanup in interface GraphPartitionExtension
