Implementing Mapping SpecialistsLocate this document in the navigation structure

A mapping specialist is used for mapping the entity data to a BOP DO request and the BOP DO response back to the entity data. Mapping specialists operate on BOP Data Objects (created during BOP Generation) and Entity Data. Each mapping specialist is provided with:

  • A BOP Data Object (BOP DO).

  • A set of BOP DOs processed by previous mapping specialists.

  • The entity data (ER_ENTITY or ER_ENTITYSET or ER_DATA). The entity data can be partially filled by previous mapping specialists.

  • Operation specific parameters.

You must create a mapping specialist class by implementing the mapping specialist interface methods for mapping. A separate mapping interface is provided for each entity operation. The mapping interface supports two methods:

  • MAP_INBOUND — is used for mapping the entity request to BOP DO request.

  • MAP_OUTBOUND — is used for mapping BOP response back to entity data.

The table below lists all the mapping interfaces for each (corresponding) entity operation:
