public class DecisionTask extends ProcessElement
Chooses one or another next process element based on AdvancedCriteria applied to `Process.state`.

If the AdvancedCriteria evaluate to true, the `nextElement` is chosen, otherwise the `failureElement`.

- ## Constructor Details

  - ### DecisionTask

    public DecisionTask()

  - ### DecisionTask

    public DecisionTask(JavaScriptObject jsObj)

  - ### DecisionTask

    public DecisionTask(String ID, String nextElement, String failureElement)

- ## Method Details

  - ### getOrCreateRef

    public static DecisionTask getOrCreateRef(JavaScriptObject jsObj)

  - ### create

    public JavaScriptObject create()
    Overrides:
      `create` in class `ProcessElement`

  - ### setCriteria

    public DecisionTask setCriteria(Criteria criteria) throws IllegalStateException
    Simple or `AdvancedCriteria` to be applied against the `Process.state`.

    Data values in this criteria prefixed with "$" will be treated as dynamic expressions as detailed in `TaskInputExpression`. Specifically, this means that for simple criteria, any property value that is a String and is prefixed with "$" will be assumed to be an expression, and for AdvancedCriteria, the same treatment will be applied to `Criterion.value`.

    Note that dynamic expressions starting with "$input" are not applicable for an DecisionTask but "$inputRecord" can be used for direct reference to `Process.state`.

    This property supports `DynamicCriteria` - use `Criterion.valuePath` to refer to values in the `Process.ruleScope`.

    Parameters:
      `criteria` - New criteria value. Default value is null
    Returns:
      `DecisionTask` instance, for chaining setter calls
    Throws:
      `IllegalStateException` - this property cannot be changed after the underlying component has been created

  - ### getCriteria

    public Criteria getCriteria()
    Simple or `AdvancedCriteria` to be applied against the `Process.state`.

    Data values in this criteria prefixed with "$" will be treated as dynamic expressions as detailed in `TaskInputExpression`. Specifically, this means that for simple criteria, any property value that is a String and is prefixed with "$" will be assumed to be an expression, and for AdvancedCriteria, the same treatment will be applied to `Criterion.value`.

    Note that dynamic expressions starting with "$input" are not applicable for an DecisionTask but "$inputRecord" can be used for direct reference to `Process.state`.

    This property supports `DynamicCriteria` - use `Criterion.valuePath` to refer to values in the `Process.ruleScope`.

    Returns:
      Current criteria value. Default value is null

  - ### setFailureElement

    public DecisionTask setFailureElement(String failureElement) throws IllegalStateException
    ID of the next sequence or element to proceed to if the criteria do not match.
    Parameters:
      `failureElement` - New failureElement value. Default value is null
    Returns:
      `DecisionTask` instance, for chaining setter calls
    Throws:
      `IllegalStateException` - this property cannot be changed after the underlying component has been created

  - ### getFailureElement

    public String getFailureElement()
    ID of the next sequence or element to proceed to if the criteria do not match.
    Returns:
      Current failureElement value. Default value is null

  - ### setNextElement

    public DecisionTask setNextElement(String nextElement) throws IllegalStateException
    Next `sequence` or `element` to execute if the criteria match the process state.

    `nextElement` does not need to be specified if this element is part of a `sequence` and has a next element in the sequence.

    Note that if there is both a `sequence` and a normal `element` with the same name in the current `Process`, the `sequence` will be used.

    Overrides:
      `setNextElement` in class `ProcessElement`
    Parameters:
      `nextElement` - New nextElement value. Default value is null
    Returns:
      `DecisionTask` instance, for chaining setter calls
    Throws:
      `IllegalStateException` - this property cannot be changed after the underlying component has been created

  - ### getNextElement

    public String getNextElement()
    Next `sequence` or `element` to execute if the criteria match the process state.

    `nextElement` does not need to be specified if this element is part of a `sequence` and has a next element in the sequence.

    Note that if there is both a `sequence` and a normal `element` with the same name in the current `Process`, the `sequence` will be used.

    Overrides:
      `getNextElement` in class `ProcessElement`
    Returns:
      Current nextElement value. Default value is null
