Property Detail
numBreaksproperty
numBreaks:int

The number of required class breaks.

This property can be used as the source for data binding.


Implementation
    public function get numBreaks():int

Constructor Detail
Classification()Constructor
public function Classification()

Creates a new instance of the Classification class.

Method Detail
classify()method
public function classify(data:Array):ClassificationResults

Classifies numerical data in a number of classes.

This method is "abstract". Its base implementation throws an error.

Parameters

data:Array — Array of numerical values.

Returns
ClassificationResults — Classification results.
ensureValidData()method 
public static function ensureValidData(data:Array, numBreaks:int):void

Ensures that the data array is specified and that the number of breaks is nonegative.

This method throws the ArgumentError if the input data are invalid.

Parameters

data:Array — Array of numerical values.
 
numBreaks:int — A number of required class breaks.

getBounds()method 
public static function getBounds(data:Array):Array

Calculates low and up bounds of values of data array.

Parameters

data:Array — Array containing numerical values.

Returns
Array — Array of two numerical values [minValue, maxValue].
onClassificationChanged()method 
protected function onClassificationChanged():void

Dispatches the classificationChanged event.

Event Detail
classificationChanged Event
Event Object Type: flash.events.Event
Event.type property = com.esri.bacore.thematicmapping.Classification.CLASSIFICATION_CHANGED

The classificationChanged event is dispatched when the classification is changed.

Constant Detail
CLASSIFICATION_CHANGEDConstant
public static const CLASSIFICATION_CHANGED:String = classificationChanged

The Classification.CLASSIFICATION_CHANGED constant defines the value of the type property of the flash.events.Event object for a classificationChanged event.

CLASSIFIER_CHANGEDConstant 
public static const CLASSIFIER_CHANGED:String = classifierChanged

The Classification.CLASSIFIER_CHANGED constant defines the type of deprecated event.
