Selection Rules

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:
