GeometryPropertySetter

Input

Features with geometries.

Set

Features with newly set traits or geometry names.

Untouched

Features that were not modified by the transformer.

<Rejected> (Dynamic)

The dynamic <Rejected> port appears when a parameter is set to a non-literal value that might make processing impossible.

For example, if a numeric parameter such as Line Width, Count Start, or Decimal Places is set to an expression, attribute value, or user parameter, it is possible to pass in a non-numeric value that cannot be used. Decimal Places = Cat cannot be processed, so the feature will be output via this port.

Rejected features will have an fme_rejection_code attribute explaining the reason for rejection.

Rejected Feature Handling: can be set to either terminate the translation or continue running when it encounters a rejected feature. This setting is available both as a default FME option and as a workspace parameter.

Geometry Part Selection

Geometry XQuery

Use this parameter to isolate only a portion of the input geometry.

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

Property to Set

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.

Overwrite Existing Properties

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.

Remove Attributes

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

Source Attributes

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

Count Output Trait	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.
Counter Name	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.
Count Start	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.
Count Scope	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

The text name or attribute containing the value for the name to be set on the geometry.

How to Set Parameter Values

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters.

Using the Text Editor

The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.

Text Editor

Using the Arithmetic Editor

The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.

Arithmetic Editor

Conditional Values

Set values depending on one or more test conditions that either pass or fail.

Parameter Condition Definition Dialog

Content

Expressions and strings can include a number of functions, characters, parameters, and more.

When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.

Content Types

String Functions	These functions manipulate and format strings.
Special Characters	A set of control characters is available in the Text Editor.
Math Functions	Math functions are available in both editors.
Date/Time Functions	Date and time functions are available in the Text Editor.
Math Operators	These operators are available in the Arithmetic Editor.
FME Feature Functions	These return primarily feature-specific values.
FME Parameters	FME and workspace-specific parameters may be used.
Creating and Modifying User Parameters	Create your own editable parameters.

Dialog Options - Tables

Table Tools

Transformers with table-style parameters have additional tools for populating and manipulating values.

Row Reordering

Enabled once you have clicked on a row item. Choices include:

Add a row
Remove a row
Move current row up one
Move current row down one
Move current row to top
Move current row to bottom

Cut, Copy, and Paste

Enabled once you have clicked on a row item. Choices include:

Cut a row - delete and copy to clipboard
Copy a row to the clipboard
Paste a row from the clipboard

Cut, copy, and paste may be used within a transformer, or between transformers.

Filter

Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output.

Import

Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers.

Reset/Refresh

Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers.

Note: Not all tools are available in all transformers.
