initialValue - The initial value, which will not be validated.

QuestionTreeNodeModel

public QuestionTreeNodeModel(com.globalmentor.urf.maqro.FollowupEvaluation followupEvaluation,
                             com.globalmentor.urf.maqro.Question initialValue)

Followup subject and initial value constructor.

Parameters:

followupEvaluation - The followup evaluation which considers this interaction a followup in this context, or null if there is no followup evaluation subject in this context.

initialValue - The initial value, which will not be validated.

Method Detail

determineLeaf

protected boolean determineLeaf()

Dynamically determines whether this node is a leaf. This version determines if there is a followup evaluation with a followup interaction, or a followup interaction in a list of followups.

Returns:

Whether this node should be considered a leaf with no children.

determineChildren

protected java.util.List<TreeNodeModel<?>> determineChildren()

Dynamically determines children. This version includes followup evaluation interactions and followups listed as general followups.

Returns:

The dynamically loaded list of children.

createFollowupInteractionTreeNode

protected AbstractRDFResourceTreeNodeModel createFollowupInteractionTreeNode(com.globalmentor.urf.maqro.FollowupEvaluation followupEvaluation,
                                                                             com.globalmentor.urf.maqro.Interaction interaction)

Creates a child node to represent an interaction and optional subject followup evaluation. This version returns a GroupTreeNodeModel if the given resource is a Group. This version returns a QuestionTreeNodeModel if the given resource is a Question. Otherwise, this method delegates to #createRDFResourceTreeNode(RDFResource, RDFResource).

Parameters:

followupEvaluation - The followup evaluation which considers this interaction a followup in this context, or null if there is no followup evaluation subject in this context.

interaction - The interaction to represent in the new node.

Returns:

A child node to represent the given property object resource.
