Integration Model
A point is enabled in Kerno where attribute values included in the template can be transformed.
The transformer class will receive the entire object and must return that same object with the attribute values transformed as desired and needed.
It is not possible to add a new attribute or remove one already contained in the object; in such a case the execution will fail. Only the value of an attribute can be modified; if any other parameter is modified, the execution will fail.
Input and Output Interfaces
The input and output DTO is the same, com.anjana.core.customers.model.EntityFormDTO, and is available in the public library customers-lib.
Within this DTO there is the entityAttributes property, which contains a list of AttributeDefinitionDTO. In this second DTO, transformations can be made on the value property. The remaining attributes cannot be modified but may be useful for the transformation that needs to be performed.
For more information about the DTOs used, refer to the API documentation by searching for the mentioned DTO or review the ANNEX with screenshots of that same documentation.
