      public class MultiDecisionTask

- - ### Constructor Detail

    - #### MultiDecisionTask

          public MultiDecisionTask()

    - #### MultiDecisionTask

          public MultiDecisionTask(com.google.gwt.core.client.JavaScriptObject jsObj)

  - ### Method Detail

    - #### getOrCreateRef

          public static MultiDecisionTask getOrCreateRef(com.google.gwt.core.client.JavaScriptObject jsObj)

    - #### create

          public com.google.gwt.core.client.JavaScriptObject create()

      Overrides:
        `create` in class `ProcessElement`

    - #### 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
