Interface Ranking

public interface Ranking

Ranking configuration for numerical attributes.

This interface has underlying access to the elements value so it can return the minimum and maximum values.

Method Summary

Modifier and Type	Method	Description
Column	getColumn()	Returns the column associated with this partition.
Number	getMaxValue(Graph graph)	Returns the maximum value in this ranking.
Number	getMinValue(Graph graph)	Returns the minimum value in this ranking.
float	getNormalizedValue(Element element, Graph graph)	Returns the element's normalized value for this ranking.
Number	getValue(Element element, Graph graph)	Returns the element's value for this ranking.
float	normalize(Number value, Interpolator interpolator, Number minValue, Number maxValue)	Normalizes the given value with the interpolator.

Method Detail

getMinValue

Number getMinValue(Graph graph)

Returns the minimum value in this ranking.

Parameters:

graph - graph to query

Returns:

minimum value

getMaxValue

Number getMaxValue(Graph graph)

Returns the maximum value in this ranking.

Parameters:

graph - graph to query

Returns:

maximum value

getValue

Number getValue(Element element,
                Graph graph)

Returns the element's value for this ranking.

Parameters:

element - element to get the value for

graph - graph this element belongs to

Returns:

the value for this ranking

getNormalizedValue

float getNormalizedValue(Element element,
                         Graph graph)

Returns the element's normalized value for this ranking.

Parameters:

element - element to get the value for

graph - graph this element belongs to

Returns:

the normalized value for this ranking

normalize

float normalize(Number value,
                Interpolator interpolator,
                Number minValue,
                Number maxValue)

Normalizes the given value with the interpolator.

The value is first put between zero and one by doing (value - min) / (max - min) and then passed to the given interpolator.

Parameters:

value - value to normalize

interpolator - interpolator

Returns:

normalized value

getColumn

Column getColumn()

Returns the column associated with this partition.

Returns:

column or null if partition not based on a column
