  1. In the following example, the header/priority field in the input message contains values of LOW, MEDIUM and HIGH. You should map these to the LineOrderPriority enum values of NOT_IMPORTANT, IMPORTANTand VERY_IMPORTANT respectively: 
    <jb:value property="priority" data="header/priority" decoder="Enum">
    <jb:decodeParam name="enumType">example.trgmodel.LineOrderPriority</jb:decodeParam>
    <jb:decodeParam name="LOW">NOT_IMPORTANT</jb:decodeParam>
    <jb:decodeParam name="MEDIUM">IMPORTANT</jb:decodeParam>
    <jb:decodeParam name="HIGH">VERY_IMPORTANT</jb:decodeParam>
</jb:value>
  2. If mappings are required, specify the enumeration type using the enumType decodeParam.
