public class SelectPointInteraction
extends GraphicInteraction
implements HotspotChoiceContainer

Like hotspotInteraction, a select point interaction is a graphic interaction. The candidate's task is to select one or more points. The associated response may have an areaMapping that scores the response on the basis of comparing it against predefined areas but the delivery engine must not indicate these areas of the image. Only the actual point(s) selected by the candidate shall be indicated. The select point interaction must be bound to a response variable with a baseType of point and single or multiple cardinality. Attribute : maxChoices [1]: integer = 1 This attribute is interpreted as the maximum number of points that the candidate is allowed to select. If maxChoices is 0 there is no restriction. If maxChoices is greater than 1 (or 0) then the interaction must be bound to a response with multiple cardinality. Attribute : minChoices [0..1]: integer = 0 The minimum number of points that the candidate is required to select to form a valid response. If minChoices is 0 then the candidate is not required to select any points. minChoices must be less than or equal to the limit imposed by maxChoices.
