Class OrderedConversationBlockSelector

java.lang.Object
  edu.indiana.iucbrf.ccbr.conversationblock.selector.AbstractConversationBlockSelector
      edu.indiana.iucbrf.ccbr.conversationblock.selector.OrderedConversationBlockSelector

All Implemented Interfaces:

ConversationBlockSelector, SwingRepresentableWithDomain, SwingRepresentable, java.io.Serializable

public class OrderedConversationBlockSelector
extends AbstractConversationBlockSelector

An OrderedConversationBlockSelector assumes that the conversation blocks passed to it either directly or through the domain are in an order-sensitive data structure. The conversation blocks are returned by getNextBlock() in this order.

Method Detail

reset

public void reset()

Description copied from interface: ConversationBlockSelector

Reset the state of the conversation block selector, to prepare for a new conversation. For some conversation block selectors, this may be a dummy operation.

initConversationImpl

protected void initConversationImpl(Problem initialProblem)

Specified by:

initConversationImpl in class AbstractConversationBlockSelector

getNextBlock

public ConversationBlock getNextBlock(Problem problemSoFar,
                                      RetrievalResults casesUnderConsideration,
                                      CCBRDomain domain)

Description copied from class: AbstractConversationBlockSelector

The conversation block returned should not be a question to which problemSoFar already has an answer. Returns null if there are no more conversation blocks to ask

Specified by:

getNextBlock in interface ConversationBlockSelector

Overrides:

getNextFeatureKeyImpl

protected FeatureKey getNextFeatureKeyImpl(Problem problemSoFar,
                                           RetrievalResults casesUnderConsideration,

toSwing

public javax.swing.JComponent toSwing(int detailLevel)

Description copied from interface: SwingRepresentable

Detail level may be ignored by implementations. If used, the standard is for detailLevel 0 to be least detail, with higher values growing more detailed. 0 is least detail, higher numbers are more
