Example match transformation

Match transformation gadgets are added to widgets.xml and are described in exactly the same way as processors (widgets) in OEDQ - See example.

The only limitation is that a match transformation must have only one input and only one output.

Example

The following is an example of a script-based gadget for an Upper Case transformation:

  <!-- ************************************************************ -->  

  <!-- script for a simple uppercase transformation -->

  <!-- ************************************************************ -->  

  <widget id="customUppercase"

          class="com.datanomic.director.match.library.util.JavaScriptGadget">

    <guidata>

      <label>%custom.uppercase.gadget</label>

      <group>transformers</group>

      <icon>script</icon>

    </guidata>

    <!-- inputs -->

    <inputs>

      <input id="1" type="string">

        <guidata><label>%customer.uppercase.input</label></guidata>

      </input>

    </inputs>

    <!-- outputs -->

    <outputs cardinality="1:1">

      <output id="1" type="string" name="result">

        <guidata><label>%customer.uppercase.output</label></guidata>

      </output>

    </outputs>

<parameters>

      <parameter name="script">

<![CDATA[

function doit()

 {

   output1 = input1.toUpperCase();

 }

]]>

      </parameter>

      <parameter name="function">doit</parameter>

    </parameters>

  </widget>
