GeometryPropertySetter
Sets selected geometry names or traits from feature attributes or constants.
Input Ports
Features with geometries.
Output Ports
Features with newly set traits or geometry names.
Features that were not modified by the transformer.
Parameters
Geometry Part Selection
Use this parameter if you want to isolate only a portion of the geometry passed in to the transformer. If no criteria are specified, the action will apply to the entire geometry at all levels.
Selection can be based on structural location, geometry name, type, appearance information, traits, trait storage types, or definition reference. The syntax used is a restricted set of XQuery, where the return clause is fixed.
The basic Geometry XQuery dialog allows you to construct simple selection queries by automatically writing the necessary query based on specified test clauses. Clicking the Switch to Advanced button opens the Advanced Editor, which allows you to type a query free-form, for more expressive queries.
Note: Once you switch to Advanced mode, you will have to clear all parameters before you can return to Basic mode.
A hierarchical geometry is represented as nodes of type geometry, with attributes containing information about traits, type, and name for each geometry.
General Parameters
- Traits From Attributes: Set traits from specified attributes.
- Traits From Counter: Set traits from an incremental counter.
- Geometry Name: Set the geometry name from specified attribute value or text.
If a property is already present and this parameter is set to No, the geometry will not be modified.
For example, if the geometry name is already set to House, then renaming as Residential will not apply if this parameter is set to No.
Determine whether the attributes will be removed from the feature after they have been set as geometry traits or not.
Note: This parameter is only valid if the Property to Set parameter is Traits From Attributes.
Traits from Attributes Parameters
Select the attributes from which to add new traits to the geometry. In particular, the name and value of the trait will match the name and value of the specified attribute.
Note: This parameter is only valid if the Property to Set parameter is Traits From Attributes.
Trait Counter Parameters
Enter the name of the trait that will contain the results, and will appear on all the geometry parts that are selected by the Geometry XQuery.
Note: This parameter is only valid if the Property to Set parameter is Traits From Counter.
Create separate sequences of numbers to be assigned, either by placing several GeometryPropertySetter transformers with each having a different counter name, or by choosing an attribute whose value will be used as the counter name as each feature passes through. (In effect, using an attribute to supply the GeometryPropertySetter name is like having a Group By option for the GeometryPropertySetter.)
Note: This parameter is only valid if the Property to Set parameter is Traits From Counter.
Specify a starting value for the counter. This is useful for applications where ranges of values have meanings in the problem domain. See Usage Notes in the Counter transformer for more tips.
Note: This parameter is only valid if the Property to Set parameter is Traits From Counter.
Specify the scope of this counter:
- Global (throughout the entire workspace): Global counters with the same Counter Name will share the same counting sequence.
- Local (for this transformer only): Local counters will each have a unique counting sequence for all features going through the same Transformer.
- Feature (for every separate feature): Feature counters will have a unique counting sequence for every single feature.
Note: This parameter is only valid if the Property to Set parameter is Traits From Counter.
Geometry Name Parameters
The text name or attribute containing the value for the name to be set on the geometry.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
