CoordinateConcatenator
Retrieves the value of all the feature's coordinates into an attribute, separated by the delimiter characters.
Parameters
This parameter can contain either an arbitrary string or a character, which is inserted between each coordinate set.
This parameter can also contain either an arbitrary string or a character, which is inserted between each x/y/z element of each coordinate.
Characters can be expressed as regular characters but they can also include any number of control characters.
Special character sequences are interpreted as shown below:
Sequence | Description |
---|---|
Ctrl+Shift+h (^H) |
Backspace (0x08) |
Ctrl+Shift+l (^L) |
Form feed (0x0c) |
Ctrl+Shift+j (^J) |
Newline (0x0a) |
Ctrl+Shift+r (^M) |
Carriage return (0x0d) |
Ctrl+Shift+i (^I) |
Tab (0x09) |
Ctrl+Shift+k (^K) |
Vertical tab (0x0b) |
Defining Special Characters
You can define special characters through the Text Editors. Click Open Text Editor from the parameter menu:
Text Editor
Enter characters using the shortcuts from the table above.
Note: To see tab characters, click the Options menu on the bottom left and select Show Spaces/Tabs.
This parameter specifies which elements in the coordinate to output. For example, if the coordinate has a value of Z, only the z coordinate will be output.
This attribute stores the value of the feature's coordinates.
Usage Notes
- This transformer works only for point, line, area, and donut features. Aggregate features will give invalid values.
- If Coordinate Element(s) to Include contains Z and the features contain two-dimensional data, only the x and y coordinates will be stored.
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.
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. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.
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.
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.
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.
These functions manipulate and format strings. | |
Special Characters |
A set of control characters is available in the Text Editor. |
Math functions are available in both editors. | |
Date/Time Functions | Date and time functions are available in the Text Editor. |
These operators are available in the Arithmetic Editor. | |
These return primarily feature-specific values. | |
FME and workspace-specific parameters may be used. | |

Dialog Options - Tables
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:
|
Cut, Copy, and Paste
|
Enabled once you have clicked on a row item. Choices include:
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.
