-------------------------------------
Summary: Provide Call backs for CRUD operations
Key: OLINGO-1034
URL: https://issues.apache.org/jira/browse/OLINGO-1034
Project: Olingo
Issue Type: New Feature
Components: odata2-core, odata2-jpa
Affects Versions: V2 2.0.7
Reporter: Santosh kumar
OData V2.0.7 doesn't have exit points for CRUD operations on Entities. Instead
of exit points Olingo supports extending its API class
{{ODataJPAProcessorDefault}} for any custom CRUD operation. The drawback of
this approach is that the developer has to duplicate all the operations even if
only {{readEntity}} has to be customized. Also any modification to the request
parameters of these operations will require re-writing the Olingo code again.
The proposal is to introduce a call back mechanism(similar to existing debug
call back) which allows the developer to introduce custom code for CRUD
operations (ex: {{readEntity}}). This approach also prevents Olingo code
duplication in client code
