You can extend the capabilities of TIBCO StreamBase® applications by creating custom programs that use the StreamBase Client libraries for Java, C++, .NET, and Python. The class references for the StreamBase API are provided in the following locations and formats:
-
Java API Documentation is the reference for the StreamBase Java Client library in Javadoc format.
-
C++ API Documentation is the reference for the StreamBase C++ Client library in Doxygen format.
-
Python API Documentation is the reference for the StreamBase Python Client library in Pydoc format.
-
StreamBase .NET Client API Documentation leads to the reference for the StreamBase .NET Client library (provided on Windows systems only).
Note
Classes and elements of classes listed in the Javadoc, Doxygen, Pydoc, and .NET documentation comprise the complete set of publicly-accessible APIs. Elements in classes that do not appear in the documentation are for internal use only, and are not supported for use in customer code.
The StreamBase Client library for different languages supports the types of StreamBase extensions described in the following table:
| StreamBase Extension | Java | C++ | Python | .NET |
|---|---|---|---|---|
| Client applications | yes | yes | yes | yes |
| Server monitor applications | yes | — | — | yes |
| Custom embedded functions | yes | yes | — | — |
| Custom embedded operators | yes | — | — | — |
| Custom embedded adapters | yes | — | — | — |
The following table shows the platforms on which these languages are supported:
| Language | Operating System |
|---|---|
| Java | Windows, UNIX, OS X |
| C++ | Windows, UNIX, OS X |
| Python | Windows, UNIX |
| .NET | Windows |
For client or monitor applications, operating system refers to the OS on which such applications will run. By contrast, since embedded functions, operators, or adapters run as part of their hosting StreamBase Server, operating system for these extensions refers to the OS hosting your expected StreamBase Server instance.
Applications or extensions developed in Java on one supported operating system will run on another. Python clients developed on Windows will run on UNIX systems, and vice versa, given the same version of Python on both hosts, and given equal access to the StreamBase Python libraries.
Applications or custom functions developed in C++ on one OS have a good chance of
successfully compiling and running on another supported OS, as long your code uses
standard libraries and published StreamBase interfaces. If your C++ code must rely on
third-party libraries provided as DLLs, .so, or
.dynlib files, then portability is not assured.
The following topics provide overviews of developing each type of custom extension:
- Developing Client Applications
-
Client applications are independent applications that either enqueue data into a running StreamBase application, or dequeue data from a StreamBase application for further processing. You can create clients using the StreamBase Java, C++, .NET, or Python Client libraries.
-
Creating .NET Clients (Windows)
-
Redistributing the .NET Client Library (Windows)
-
Migrating .NET Clients (Windows)
-
StreamBase .NET Client API Documentation (Windows)
- Developing Custom Functions
-
Custom functions extend the StreamBase expression language, and can be called in expressions from within StreamBase components. They can be written with either the Java or C++ Client libraries.
- Developing Java Operators
-
Java operators add custom functionality within the flow of your StreamBase application. They are created with the Java Client library.
- Developing Embedded Adapters
-
Embedded adapters can enqueue or dequeue data like clients, but adapters are not independent. They are included as components within StreamBase applications, and start and stop with the StreamBase application. Embedded adapters are created with the Java Client library.
- Developing StreamBase Monitor Applications
-
Use the StreamBase Monitor API to create client programs that obtain and process statistical data about applications on the currently running StreamBase Server. The Monitor API is a subset of the StreamBase Java and .NET Client libraries.
