Example - Dynamic Expression to Construct a Dynamic Struct

An Expression transformation has a dynamic port from which you want to construct a struct.

An Expression transformation has the following generated input ports:

Name		String
Street	String
City		String
State		String
Zip		Integer

The transformation contains a dynamic complex output port called d_structAddress. You want to construct a struct and return the result to d_structAddress.

You create a port selector AddressPS and define the selection rules to include the following ports by name:

Street	String
City		String
State		String
Zip		Integer

Then, you create a dynamic expression with the STRUCT function.

The following image shows a dynamic expression that references a port selector AddressPS:

In the

Output Port Settings

area, specify the port selector AddressPS as the base port.

The dynamic expression creates the following struct with the elements from the port selector:

d_structAddress{
  Street	String
  City		String
  State		String
  Zip		Integer
}
