Interface IlvPartitioner<CIT extends IlvClusterId>

All Known Implementing Classes:

IlvAbstractPartitioner, IlvColumnValuePartitioner, IlvCustomScalePartitioner, IlvDatePartitioner, IlvHostnamePartitioner, IlvPathPartitioner, IlvStringPartitioner, IlvUniformScalePartitioner

public interface IlvPartitioner<CIT extends IlvClusterId>

This interface describes how to partition a set of objects. It does so by assigning an IlvClusterId to each object and by collecting objects with the same IlvClusterId together in a group (cluster).

The type parameter CIT denotes the type to which all IlvClusterIds created by the classifiers of this class belong.

Since:

JViews 7.5

Method Summary

Modifier and Type	Method and Description
void	addPartitionerListener(PartitionerListener listener) Adds a change listener to this operator.
IlvClassifier<CIT>	createClassifier(Object parent, IlvClassifier outerClassifier, IlvClusterId outerParentClusterId) Creates a classifier that can evaluate the children objects of the given parent object one by one.
void	dispose() Cleans up this partitioner and drops references to models to help garbage collection.
void	removePartitionerListener(PartitionerListener listener) Removes a change listener from this operator.

Method Detail

createClassifier

IlvClassifier<CIT> createClassifier(Object parent,
                                    IlvClassifier outerClassifier,
                                    IlvClusterId outerParentClusterId)

Creates a classifier that can evaluate the children objects of the given parent object one by one.

Parameters:

parent - The parent object whose children objects are to be grouped, or null.

outerClassifier - The last returned value of this function for the parent object or its nearest parent, or null if this is the first application of this partitioner to the objects.

outerParentClusterId - The IlvClusterId that was produced by the outerClassifier for the parent object or its nearest parent. This is null if this is the first application of this partitioner to the objects.

dispose

void dispose()

Cleans up this partitioner and drops references to models to help garbage collection.

Note: After calling this function, this partitioner is no longer functional.

addPartitionerListener

void addPartitionerListener(PartitionerListener listener)

Adds a change listener to this operator.

removePartitionerListener

void removePartitionerListener(PartitionerListener listener)

Removes a change listener from this operator.
