Creating a Port Selector

Creating a Port Selector

Create a port selector to determine which ports to use in a dynamic expression, a lookup condition, or a joiner condition.
  1. Click the
    Port Selectors
    tab.
  2. In the
    Port Selectors
    area, click
    New
    .
    The Developer tool creates a port selector with a default selection rule that includes all ports.
  3. In the
    Port Selectors
    area, change the port selector name to a unique name.
  4. If you are working on the Joiner transformation or the Lookup transformation, choose the scope.
    The available ports change based on the group of ports that you choose.
  5. In the
    Selection Rules
    area, select an
    Operator
    .
    • Include. Create a rule that includes ports for the port selector. You must include ports before you can exclude ports.
    • Exclude. Create a rule that excludes specific ports from the port selector.
  6. Choose the
    Selection Criteria
    .
    • By Name. Select specific ports by name. You can select the port names from a list of ports in the scope.
    • By Type. Select ports by type. You can select one or more data types.
    • By Pattern. Select ports by a pattern of characters in the port name. You can search with specific characters or you can create a regular expression.
    The following image shows the Port Selector tab:
    The port selector tab shows a port selector called Join_Selector. The scope is Detail, which is the Detail input group of a Joiner transformation. The Operator is Include. The Selection Criteria is By Pattern. The Detail column says prefix: City. The Port preview column shows City and City2 ports.
  7. Click the
    Detail
    column.
    The
    Input Rule Detail
    dialog box appears.
  8. Select the values to filter ports by.
    • By Name. Choose to create a port list by value or by a parameter. Click
      Choose
      to select the ports in the list.
    • By Type. Select one or more data types from a list. The
      Port Preview
      area shows ports of the types that you select.
    • By Pattern. Choose to search the prefix or suffix of the port name for a specific pattern of characters. Or, choose to create a regular expression to search with. Configure a parameter or configure the pattern to search with.
    The
    Port Preview
    area shows the ports in the port selector as you configure the rules.
  9. To reorder the ports in the port selector, select
    Reorder generated ports according to the input rule order
    .
