Selection Rules

The selection rules associated with a port selector determine the ports to include in the port selector.

When you create the selection rules, the

Port Preview

panel shows the ports that qualify from the current input ports. These ports might change. Configure the selection rules to accommodate ports from different sources.

Create selection rules based on the following criteria:

Operator: Includes or excludes the ports that selection rules return. Default is include. You must include ports before you can exclude ports.
Selection Criteria: The type of selection rule you want to create. You can create a rule based on the column name, port type, pattern, or complex data type definition. To include ports based on the column name, search for specific names or search for a pattern of characters in the name.
Detail: The values to apply to the selection criteria. If the selection criteria is by column name, configure the string or name to search for. If the selection criteria is by port type, select the port types to include.

The following table describes the selection criteria and how to specify the details for the criteria:

Selection Criteria	Description	Detail
All	Includes all ports.	No details required.
Name	Filters ports based on the port name.	Select the port names from a list of values or use a parameter of type Port or Port List.
Type	Filters ports based on the data type of each port.	Select data types from a list.
Pattern	Filters ports by a string of characters in the name or by a regular expression.	Choose prefix, suffix, or regular expression as the pattern type for the port name. Then, enter a value for the pattern or use a parameter of type String.
Complex Data Type Definition	Filters ports by a complex data type definition.	Choose prefix, suffix, or regular expression as the pattern type for the complex data type definition. Then, enter a value for the pattern or use a parameter of type String.
