Copies the value of an attribute whose name is referenced in the source attribute. The value is added to a newly created attribute.
Features with attributes.
Features with a copy of the value of the referenced source attribute.
The attribute containing a reference to another attribute.
The new attribute that will contain a copy of the source attribute's value.
Suppose you have two attributes:
- Attribute A has the value B
- Attribute B has the value 999
In the transformer parameters:
- Set the Source Attribute parameter to A.
- Create a new Destination Attribute called newAttr.
When you run the workspace, the value 999 (from Attribute B) is added to the destination attribute, as shown in the log file:
2010-11-27 18:13:38| 0.1| 0.0|INFORM|Attribute(string) : `A' has value `B'
2010-11-27 18:13:38| 0.1| 0.0|INFORM|Attribute(string) : `B' has value `999'
2010-11-27 18:13:38| 0.1| 0.0|INFORM|Attribute(string) : `_newAttr' has value `999'
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.
