      public class DecisionGateway
      extends MultiDecisionTask

  Chooses a next element in a `Process` by evaluating a series of criteria against the `Process.state` and choosing the element associated with the criteria that matched, or a `defaultElement` if none of the criteria match.

          public DecisionGateway()

    - #### DecisionGateway

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

  - ### Method Detail

    - #### getOrCreateRef

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

    - #### create

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

      Overrides:
        `create` in class `MultiDecisionTask`

    - #### setCriteriaMap

          public DecisionGateway setCriteriaMap(java.util.Map<java.lang.String,Criteria> criteriaMap)
                                         throws java.lang.IllegalStateException

      Deprecated. In favor of `decisionList` as of SmartGWT release 12.1
      A Map from `ProcessElement.ID` to Criteria that will cause this ProcessElement to be chosen as the next element if the criteria matches.

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

      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 "$input" are not applicable for an decisionGateway but "$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:
        `criteriaMap` - New criteriaMap value. Default value is null
      Returns:
        `DecisionGateway` instance, for chaining setter calls
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the underlying component has been created

    - #### getCriteriaMap

          public java.util.LinkedHashMap getCriteriaMap()

      Deprecated. in favor of `MultiDecisionTask.getDecisionList()`.
      A Map from `ID` to Criteria that will cause this ProcessElement to be chosen as the next element if the criteria matches.
      Returns:
        LinkedHashMap

    - #### setDefaultElement

          public void setDefaultElement(ProcessElement defaultElement)
                                 throws java.lang.IllegalStateException

      Throws:
        `java.lang.IllegalStateException`

        `MultiDecisionTask.setDefaultElement(String)`
