AttributeDereferencer

Sets an attribute value by following a reference from one attribute to another, where the first attribute contains the name of the desired (second) attribute. The referenced value is retrieved and assigned to a new attribute.

Typical Uses

  • Carry out a join where there is no join key, but one attribute is a pointer to the required value

How does it work?

The AttributeDereferencer receives the name of an attribute in the Input Attribute parameter. The Input Attribute’s value references (is the name of) another attribute, and the value of this secondary attribute will be added to a newly created Dereferenced Value attribute.
