Inventory Interceptor

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 but with the attribute values transformed as desired and needed.

A new attribute cannot be added, nor can an existing one be removed from the object; if this occurs, execution will fail. Only the value of an attribute can be modified; if any other parameter is modified, execution will fail.

Input and Output Interfaces

The input and output DTO is the same, com.anjana.core.customers.model.EntityFormDTO, and it is available in the public library customers-lib.

Inside this DTO is the entityAttributes property; this property contains a list of AttributeDefinitionDTO. In this second DTO, transformations can be made to the value property. The rest of the attributes cannot be modified but may be useful for the transformation that needs to be done.

For more information about the DTOs used, check the API documentation by searching for the mentioned DTO, or check the ANNEX with screenshots of that same documentation
