Enum Types

Enum Types are an experimental extension of the elements metamodel. They allow you to create ValueTypes for which the possible values are enumerated in the model.

Enum-types are split into 2 expander bundles. Use the enum-type-rest-expanders if you want to integrate with the rest-expanders.

Defining EnumType​

EnumTypes are defined in a Component. In the Component model directory, add your EnumType models under valueTypes.

E.g. this describes a FileChangeType enum:

<valueType name="FileChangeType" type="enumTypeElements::EnumType">
  <packageName>org.normalizedsystems.quests</packageName>
  <values>
    <enumValueType name="ADD">
      <description>File was created</description>
    </enumValueType>
    <enumValueType name="MODIFY">
      <description>File was updated</description>
    </enumValueType>
    <enumValueType name="DELETE">
      <description>Files was removed</description>
    </enumValueType>
    <enumValueType name="RENAME">
      <description>File was moved or renamed</description>
    </enumValueType>
    <enumValueType name="COPY">
      <description>File is a copy from another file</description>
    </enumValueType>
  </values>
</valueType>

The ValueType can then be used as target for ValueField#type:

<field name="changeType">
  <valueField>
    <type name="FileChangeType"/>
  </valueField>
</field>

You can use the defaultValue option on a Field to define one of the enums as initial value:

<field name="changeType">
  <valueField>
    <type name="FileChangeType"/>
  </valueField>
  <options>
    <defaultValue>MODIFY</defaultValue>
  </options>
</field>

Known Issues​

  • When changing a field to the new EnumType, also update the commands for the REST APIs, otherwise it will not compile.
  • You will have to use at least version 1.15.9 of the micro-radiant, otherwise your project will not be able to load.

Missing Integrations​

  • Angular-expanders
  • Knockout UI
