The TIBCO StreamBase® Bidirectional CSV Socket Reader and Writer adapters receive and send data over a socket connection in comma-separated value (CSV) format. This sample demonstrates how to use the Bidirectional CSV socket adapter to communicate with the CSVSocketReader and CSVSocketWriter.
The client is configured to receive CSV input using the Bidirectional CSV Socket adapter, and uses the Bidirectional CSV Socket Writer to send each incoming tuple to all connections. The server is separated into two parts. The first part, ServerReader, reads data from the client using the CSV Socket Reader. The second part, ServerWriter, writes data back to the client using the CSV Socket Writer. Both the CSVSocketReader and CSVSocketWriter adapter require a connection to the client for this to work because, unlike the Bidirectional Socket adapter, they do not share a connection.
In StreamBase Studio, import this sample with the following steps:
From the top-level menu, select→ .
bidito narrow the list of options.
Select Bidirectional CSV Socket Input/Output Adapter from the StreamBase Standard Adapters category.
StreamBase Studio creates a single project containing the sample files.
In the Project Explorer view, open the sample you just loaded.
If you see red marks on a project folder, wait a moment for the project to load its features.
If the red marks do not resolve themselves after a minute, select the project, right-click, and select→ from the context menu.
BiDirectionalSocketWithCSVSocketReaderAndCSVSocketWriter.sbappfile and click the Run button. This opens the SB Test/Debug perspective and starts the module.
In the Manual Input view, select the
ControlClientStream, then enter
CONNECTinto the command field and click .
In the Output Streams view, observe tuples emitted on the
Select any tuple emitted from either stream and inspect tuple data fields in the Variables view below the output streams to analyze and understand their structure.
When done, press F9 or click the Terminate EventFlow Fragment button.
When you load the sample into StreamBase Studio, Studio copies the sample project's files to your Studio workspace, which is normally part of your home directory, with full access rights.
Load this sample in StreamBase Studio, and thereafter use the Studio workspace copy of the sample to run and test it, even when running from the command prompt.
Using the workspace copy of the sample avoids permission problems. The default workspace location for this sample is:
