Components Nested within a Mapper

Components Nested within a Mapper

Within a
Mapper
, you can nest the following components:
  • Any number of
    Map
    actions. The actions retrieve a data holder from the output and write the content to the output.
  • Optionally, any number of Mapper anchors. For more information, see the Mapper Anchor Component Reference.
  • Optionally, any number of additional actions.
The
Map
actions and the Mapper anchors can be in any sequence. You can also insert other actions in the sequence.
Notice that a Mapper uses
Map
actions rather than Mapper anchors to write to the output XML. This may seem a little different from Parsers and Serializers, where the output is created by anchors and serialization anchors, respectively. Actually, this is just a terminology issue. The
Map
action could have been defined as a Mapper anchor. It is defined as an action because it is useful in other circumstances, unrelated to Mappers.
