ilog.views.chart.datax.adapter.partition.IlvUniformScalePartitioner

All Implemented Interfaces:

IlvPartitioner<IlvIntervalClusterId>

public class IlvUniformScalePartitioner
extends IlvColumnValuePartitioner<IlvIntervalClusterId>

This class partitions a set of objects according to the value of a model column, as a number, by dividing the value range [min,max] into intervals of equal length.

For this partitioner, all IlvClusterIds are of type IlvIntervalClusterId.

Since:

JViews 7.5

Constructor Detail

IlvUniformScalePartitioner

public IlvUniformScalePartitioner(IlvObjectModelWithColumns model,
                                  IlvDataColumnInfo column,
                                  int depth,
                                  int subIntervalCount)

Creates an instance of this class.

Parameters:

model - The model being partitioned.

column - The column whose values are used for partitioning.

depth - The nesting depth of the clusters produced.

subIntervalCount - The number of groups into which to partition each interval.

Method Detail

createClassifier

public IlvClassifier<IlvIntervalClusterId> 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

public 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.

Specified by:

dispose in interface IlvPartitioner<IlvIntervalClusterId>

Overrides:

dispose in class IlvColumnValuePartitioner<IlvIntervalClusterId>
