Transformers

XSKOData2ODataHTransformer

Uses the OData2ODataHTransformer.transform() method. The xsodata modification artifacts are converted to odata artifacts. See the table for the supportable operations.

xsodata modification artifacts	convert to odata
create using	on
forbidden	forbid
before	before
after	after
precommit	not supported
postcommit	not supported

Example of .xsodata will generated the following OData2ODataHTransformer

"sample.odata::table1"
      update events (before "sample.odata::beforeMethod", precommit "sample.odata::beforeMethod")
      delete events (after "sample.odata::afterMethod")
      create forbidden;

| ODATAH_METHOD | ODATAH_TYPE | ODATAH_HANDLER             |
|---------------|-------------|----------------------------|
| update        | before      | sample.odata::beforeMethod |
| delete        | after       | sample.odata::afterMethod  |
| create        | fordid      | N/A                        |

Example of .xsodata will generated the following OData2ODataHTransformer

     create using "sample.odata::createMethod"
     update events (precommit "sample.odata::precommitMethod")
     delete forbidden;

| ODATAH_METHOD | ODATAH_TYPE | ODATAH_HANDLER             |
|---------------|-------------|----------------------------|
| create        | on          | sample.odata::createMethod |
| delete        | fordid      | N/A                        |

XSKOData2ODataMTransformer

Dirigible Odata supports the following Multiplicity values: ZERO_TO_ONE("0..1"), MANY("*"), ONE("1");

XSODATA Multiplicity '1..*' is NOT SUPPORTED
