Interface IF_GEF_GDB_SERVICE
Use
The framework provides the interface to access the GIS database, which is SAP HANA by default.
Methods
The Interface uses the following methods:
Used to create geometry in the SAP HANA database.
| Parameter | Description |
|---|---|

Used to query geometry in the SAP HANA database.
| Parameter | Description |
|---|---|
| IO_REQ_CONTEXT |
The context of a general query request that the application needs to run against the GIS database. Type IF_GEF_REQ_EDIT |
| ER_STRUCTDESCR |
The query result is returned in a table of dynamic structure. The metadata of the structure is included in this parameter. Type ref to CL_ABAP_STRUCTDESCR |
| ER_RESULT_REF |
The query result is returned as a dynamic table referred by this parameter. Type DATA |
Used to read specified geometries in the SAP HANA database.
| Parameter | Description |

| ET_GDB_OBJECT |
Table of geometry records requested by the input parameter. Type GEFT_GDB_GEOM |
Used to read geometries in the SAP HANA database for the specified business objects.
| Parameter | Description |
|---|---|
| IV_BO_ID |
Type of business object. Type GEF_BO_ID |
| IT_OBJKEY |
Table of keys of requested business objects. Type GEFT_OBJKEY |
| IV_GEOMETRY_TYPE |
