Context Based Mapping

Context based mapping can be specified by using the map-id attribute. Note that we also support nested context mapping by specifying a map-id at the field level. 

         
<mapping map-id="caseA">
   <class-a>org.dozer.vo.context.ContextMapping</class-a>
   <class-b>org.dozer.vo.context.ContextMappingPrime</class-b>
   <field-exclude>
     <a>loanNo</a>
     <b>loanNo</b>
   </field-exclude>
   <field map-id="caseC">
     <a>contextList</a>
     <b>contextList</b>
     <b-hint>org.dozer.vo.context.ContextMappingNestedPrime
     </b-hint>
   </field>
</mapping>

<mapping map-id="caseB">
  <class-a>org.dozer.vo.context.ContextMapping</class-a>
  <class-b>org.dozer.vo.context.ContextMappingPrime</class-b>
</mapping>

<mapping map-id="caseC">
  <class-a>org.dozer.vo.context.ContextMappingNested</class-a>
  <class-b>org.dozer.vo.context.ContextMappingNestedPrime
  </class-b>
   <field-exclude>
     <a>loanNo</a>
     <b>loanNo</b>
   </field-exclude>
</mapping>

<mapping map-id="caseD">
  <class-a>org.dozer.vo.context.ContextMappingNested</class-a>
  <class-b>org.dozer.vo.context.ContextMappingNestedPrime
  </class-b>
</mapping>
</mappings>

To use a particular context when invoking the Mapper, you simply specify the map-id in your mapping call. 

         
ContextMappingPrime cmpA = 
    mapper.map(cm, ContextMappingPrime.class, "caseA");
