About This Sample

This sample illustrates the use of the TIBCO StreamBase® File Reader Adapter and TIBCO StreamBase® File Writer Adapter working together to read a templated file into the system and use the inbound tuple to replace values in the read file and then write that information back out to another file.

Importing This Sample into StreamBase Studio

In StreamBase Studio, import this sample with the following steps:

  • From the top menu, select File → Load StreamBase Sample.

  • Select File reader input adapter using replacement fields to write a template file output from the StreamBase Standard Adapters category.

  • Click OK.

StreamBase Studio creates a single project containing the sample files.

Running This Sample in StreamBase Studio

  1. In the Package Explorer, double-click to open the TemplatedReadWrite.sbapp application. Make sure the application is the currently active tab in the EventFlow Editor.

  2. Click the Run button. This opens the SB Test/Debug perspective and starts the application.

  3. In the Manual Input view, Fill out the fields available and then click Send Data to send the tuple.

  4. In the Application Output view, observe tuples emitted on the ReadStatus and Data output streams.

  5. Repeat the process and send as many tuples as desired to test the functionality.

  6. Press F9 or click the Stop Running Application button.

  7. The sample application will produce an Output.txt file with the results formatted per the Template.txt template file.
