Chandan V.A commented on OLINGO-103:
------------------------------------
Following are the improvements
# A new interface is introduced -
*org.apache.olingo.odata2.jpa.processor.api.ODataJPAResponseBuilder* in jpa-api
module.
# A default internal implementation of the interface is provided -
*org.apache.olingo.odata2.jpa.processor.core.ODataJPAResponseBuilderDefault* in
jpa-core module.
# A reference to default implementation could be obtained using the
ODataJPAAccessFactory class as shown below
{code}ODataJPAFactory.createFactory().getODataJPAAccessFactory().getODataJPAResponseBuilder(<ODataJPAContext>);{code}
# The ODataJPAProcessor abstract class is enhanced by encapsulating an instance
of type ODataJPAResponseBuilder. Classes extending the abstract class gets
access to the response builder via the protected member variable
*responseBuilder*. The subclass also gets access to the OData request processor
via the protected member variable *jpaProcessor*.
> Expose ODataJPAResponseBuilder for External Usage

> Project: Olingo
> Issue Type: Improvement
> Components: odata2-jpa
> Reporter: Chandan V.A
> Assignee: Chandan V.A
> Fix For: V2 1.1.0

>
> At times it is required to write an own OData - JPA Processor instead of
> using the default OData - JPA processor -
> org.apache.olingo.odata2.jpa.processor.core.ODataJPAProcessorDefault.
> One could implement a OData JPA processor by extending the
> org.apache.olingo.odata2.jpa.processor.api.ODataJPAProcessor class. The class
> encapsulates an instance for processing OData request
> (org.apache.olingo.odata2.jpa.processor.api.access.JPAProcessor).
> However to build an OData response from a JPA Entity for a given OData
> request there is no such instance encapsulated.
> Hence extend ODataJPAProcessor class to encapsulate a OData JPA Response
> builder which can be used by the subclasses for building OData Responses from
> JPA Entity.
