setDecisionList

public MultiDecisionTask setDecisionList(DecisionBranch... decisionList)
                                  throws java.lang.IllegalStateException

List of DecisionBranchs to be processed to find the first with matching criteria. The specified DecisionBranch.targetTask is then used to identify the the next element.

If no criteria is matched the next element is defaultElement or the workflow is finished.

When providing a MultiDecisionTask in XML, the decisionList is expressed as:

      <MultiDecisionTask ID="continentDecision" description="Which continent?" defaultElement="summary">
          <decisionList>
              <decisionBranch targetTask="europeVATTask">
                  <criteria fieldName="order.continent" operator="equals" value="Europe" />
              </decisionBranch>
              ...
          </decisionList>
      <MultiDecisionTask>
  

Parameters:

decisionList - New decisionList value. Default value is null

Returns:

MultiDecisionTask instance, for chaining setter calls

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getDecisionList

public DecisionBranch[] getDecisionList()

List of DecisionBranchs to be processed to find the first with matching criteria. The specified DecisionBranch.targetTask is then used to identify the the next element.

If no criteria is matched the next element is defaultElement or the workflow is finished.

When providing a MultiDecisionTask in XML, the decisionList is expressed as:

      <MultiDecisionTask ID="continentDecision" description="Which continent?" defaultElement="summary">
          <decisionList>
              <decisionBranch targetTask="europeVATTask">
                  <criteria fieldName="order.continent" operator="equals" value="Europe" />
              </decisionBranch>
              ...
          </decisionList>
      <MultiDecisionTask>
  

Returns:

Current decisionList value. Default value is null

setDefaultElement

public MultiDecisionTask setDefaultElement(java.lang.String defaultElement)
                                    throws java.lang.IllegalStateException

Next element to pick if no criteria match. If this decision is part of a sequence and has a next element in the sequence, the defaultElement is assumed to be the next element and does not need to be specified.

Parameters:

defaultElement - New defaultElement value. Default value is null

Returns:

MultiDecisionTask instance, for chaining setter calls

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getDefaultElement

public java.lang.String getDefaultElement()

Next element to pick if no criteria match. If this decision is part of a sequence and has a next element in the sequence, the defaultElement is assumed to be the next element and does not need to be specified.

Returns:

Current defaultElement value. Default value is null
