Activity
An
OpenSpirit activity that can convert an input of Esri WKT (Well Known
Text) into the corresponding OpenSpirit geometry type. The activity can
also perform the reverse operation and convert an OpenSpirit geometry
type into the corresponding Esri WKT.
OpenSpirit Geometry Conversion Configuration Fields
| Field | Global Var? | Optional? | Description |
| Name | No | No | User assigned name given to activity |
| Description | No | Yes | User assigned description (optional) |
| Conversion Type | No | No | Specifies the type of conversion to perform (e.g. Esri WKT to OpenSpirit geometry or OpenSpirit geometry to Esri WKT). |
| Geometry Type | No | Yes | Specifies the OpenSpirit geometry type to process. If the conversion type is Esri WKT to OpenSpirit geometry, the geometry type selected will show up on the activity's output panel. If the conversion type is OpenSpirit geometry to Esri WKT, the geometry type selected will show up on the activity's input panel. |
See TIBCO ActiveMatrix BusinessWorks Process Design Guide for more information about mapping and transforming input data.
The input for the activity is the following.
| Input Item | Datatype | Description |
| Parameters | Complex | Root element for all input elements |
| EsriWKT | String | This is the Esri WKT to turn into an OpenSpirit geometry. This element is only shown if the conversion type is Esri WKT to OpenSpirit geometry. |
| CRS | OspCRS | The coordinate system associated with the Esri WKT. This element is only shown if the conversion type is Esri WKT to OpenSpirit geometry. |
| Polygon/Point/LineString | OspPolygon,
OspPoint, OspLineString |
This element is only shown if the conversion type is OpenSpirit geometry to Esri WKT. The geometry type drop down on the configuration panel determines the actual type that is rendered. |
The output for the activity is the following.
| Output Item | Datatype | Description |
OspOutput |
Complex | The root element for all output items for the activity. |
| Polygon/Point/LineString | OspPolygon,
OspPoint, OspLineString |
If the conversion type is Esri WKT to OpenSpirit geometry, then this is the corresponding OpenSpirit geometry that the input Esri WKT was converted into. If the conversion type is OpenSpirit geometry to Esri WKT, then this is simply an echo of the input supplied. The geometry type drop down on the configuration panel determines the actual type that is rendered. |
| EsriWKT | String | If the conversion type is OpenSpirit geometry to Esri WKT, then this is Esri WKT that the input OpenSpirit geometry was converted into. If the conversion type is Esri WKT to OpenSpirit geometry, then this is simply an echo of the input supplied. |
| CRS | OspCRS | If the conversion type is OpenSpirit geometry to Esri WKT, then this is the coordinate system associated with the input OpenSpirit geometry. If the conversion type is Esri WKT to OpenSpirit geometry, then this is simply an echo of the input supplied. |
The Error Output tab lists the possible exceptions that can be thrown by this activity.
| Exception | Thrown When ... |
OspException msg msgCode |
The geometry conversion
could not be successfully executed.
The msg element should contain some indication of the reason. The error code (see list of possible codes) |
