Create a function selector resource configuration
The configuration of a function selector, which determines which operation to call on an export interface, is discussed.
In this example, the module and the WebSphere Adapter for Flat Files had been previously set up. Creating a function selector resource configuration with the binding resource configuration wizard is shown.
Procedure
- Right-click the module and from the menu select New > Binding Resource Configuration. The Binding Resource Configuration window opens. Select Function Selector and click Next.
- Select either an existing function selector or create your own custom function selector that is available in your workspace on the class path.
In the second case, the Function selector class name field lets you select a class from an existing collection of custom function selectors you have created previously. If that only classes on the class path with a name following this pattern <class name>Properties are selectable.
Click Next.
- Once you have selected your function selector, the wizard allows you to proceed to the Function Selector Properties page, where you can add properties such as, in this case, the incoming text file with the customer data.
The properties you are configuring are rules on how to map from the name of a file to an object name. The rule is a regular expression for a file name. In the following example, if a file named Customer.txt is placed in the event directory, which is used by the WebSphere Adapter for Flat Files as the point where files are read, the function selector will map the file to an operation named emit<object name>, so emitCustomer. For the object name, you would specify the name of your input type. When you construct your input operation, you would select the input type. Click Next.
- In the final page you specify the name of your function selector and click Finish to generate it. The function selector resource configuration is completed and shown in the editor. The function selector is listed in the navigation under Binding Resources. In the editor, you can choose to expose this function selector resource configuration to other bindings beside a binding chosen by the wizard by selecting the binding in the Select bindings table.
