Class IntersectionEvaluator

java.lang.Object

com.technia.tvc.gridbrowser.model.IntersectionEvaluator

public class IntersectionEvaluator
extends java.lang.Object

The IntersectionEvaluator is used in the Grid Browser for many purposes, such as evaluating the intersection's between the row and column axis.

The most common use case for overriding this class is to be able to select additional data on the intersections and make them available at a later time when the grid browser is being rendered. For this purpose, the methods you have to override are prepareIntersectionDataEvaluation(EvaluationInput) and getIntersectionData(EvaluatedData).

6.3.0

                              int index)

Parameters:

model - The grid browser model

ii -

fromRowToColumn - True if the check is done from the row to the column

id - The id

otherId - The other id

row - The table data for the row

column - The table data for the column

index - The index within

Returns:

True if the row/column combination represents an intersection

Since:

6.3.0

prepareIntersectionDataEvaluation

public void prepareIntersectionDataEvaluation(EvaluationInput input)

Subclasses may override this method to add select statements that will be selected on the intersection's

Parameters:

input -

Since:

2012.3.0

getIntersectionData

public IntersectionData getIntersectionData(EvaluatedData data)

This method returns null by default.

Subclasses may override this method together with the prepareIntersectionDataEvaluation(EvaluationInput) to specify select statements to be applied on the intersections.

Parameters:

data - The evaluated data

Returns:

An object that extends from the base class IntersectionData
