## Class XORGateway

- java.lang.Object
- - com.smartgwt.client.core.BaseClass

- All Implemented Interfaces:
    com.google.gwt.event.shared.HasHandlers

      public class XORGateway
      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`.

  Note that "XOR" in `XORGateway` means "exclusive or" - only one next element is chosen.

  - ### Method Detail

    - #### getOrCreateRef

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

    - #### create

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

      Overrides:
        `create` in class `ProcessElement`

    - #### setCriteria

          public void setCriteria(Criteria criteria)
                           throws java.lang.IllegalStateException

      Simple or `AdvancedCriteria` to be applied to the task inputs. These will be applied to either the data indicated by the `Task.inputField` or to the "inputRecord" if multiple input fields are declared (see `TaskIO`).
      Parameters:
        `criteria` - New criteria value. Default value is IR
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the underlying component has been created

    - #### getCriteria

          public Criteria getCriteria()

      Simple or `AdvancedCriteria` to be applied to the task inputs. These will be applied to either the data indicated by the `Task.inputField` or to the "inputRecord" if multiple input fields are declared (see `TaskIO`).
      Returns:
        Current criteria value. Default value is IR

    - #### setFailureElement

          public void setFailureElement(java.lang.String failureElement)
                                 throws java.lang.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
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the underlying component has been created

    - #### getFailureElement

          public java.lang.String getFailureElement()

      ID of the next sequence or element to proceed to if the criteria do not match.
      Returns:

          public void setNextElement(java.lang.String nextElement)
                              throws java.lang.IllegalStateException

      ID of the next `sequence` or {process.elements,element} to procede to if the criteria match the process state. If this gateway is part of a `sequence` and has a next element in the sequence, `nextElement` does not need to be specified.
      Overrides:
        `setNextElement` in class `ProcessElement`
      Parameters:
        `nextElement` - New nextElement value. Default value is null
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the underlying component has been created

    - #### getNextElement

          public java.lang.String getNextElement()

      ID of the next `sequence` or {process.elements,element} to procede to if the criteria match the process state. If this gateway is part of a `sequence` and has a next element in the sequence, `nextElement` does not need to be specified.
      Overrides:
        `getNextElement` in class `ProcessElement`
      Returns:
        Current nextElement value. Default value is null

    - #### setFailureElement

          public void setFailureElement(ProcessElement failureElement)

        `java.lang.IllegalStateException`
      See Also:
        `setFailureElement(String)`

    - #### setNextElement

          public void setNextElement(ProcessElement nextElement)
