Constructor Detail

InstructionFlowChartNode

protected InstructionFlowChartNode()

InstructionFlowChartNode

public InstructionFlowChartNode(java.lang.String instructionText,
                                FlowChartNode nextNode)

Creates a new instance of InstructionFlowChartNode. This node will provide instructions, but ask no question. If nextNode == null, then no further conversation blocks will be presented (it is the end of the flowchart)

Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

nextNodesIterator

public java.util.Iterator nextNodesIterator()

Specified by:

nextNodesIterator in class FlowChartNode

getFeatureQuestioned

public FeatureKey getFeatureQuestioned()

Description copied from class: FlowChartNode

Get the key of the feature questioned by this node. May be null, for an InstructionFlowChartNode, for example.

Specified by:

getFeatureQuestioned in class FlowChartNode

getImmediateNextNode

protected FlowChartNode getImmediateNextNode(Feature answer)

Specified by:

getImmediateNextNode in class FlowChartNode

getConversationBlockObject

public ConversationBlock getConversationBlockObject(CCBRDomain domain)

Description copied from class: FlowChartNode

Get the ConversationBlock object corresponding to this node.

Specified by:

getConversationBlockObject in class FlowChartNode

assignChild

public void assignChild(int nextNodeIndex,
                        FlowChartNode newNode)

Description copied from class: FlowChartNode

Give this node a child. The nextNodeIndex corresponds to the answer's position in the FSMFeature.
