Find details on the SPL language, toolkits, APIs, commands, and more.
You can use SPLDOC markup in the descriptions associated with the SPL artifacts in a toolkit. The spl-make-doc command generates HTML documentation from the marked up artifacts.
You can use SPLDOC to mark up different kinds of links.

streamtool
Develop stream applications with the Streams Processing Language (SPL), Java, and Python.
Resolve problems with Teracloud® Streams using the troubleshooting tools provided with the product as well as the resources offered by Teracloud Support.
Application programming interfaces (APIs) provide functions that simplify applications development.
You can specify or change configuration parameters when you use the submitjob or updateoperators operations. The settings control submission constraints, host constraints and locations, and operator status. Parameters are captured and updated in the configuration JSON file. When you change the values in the job configuration overlay file, the changes override any previously set values.

Teracloud® Streams provides a number of commands you use to perform tasks.
An operator model is an XML document that describes the basic properties of a primitive operator.
Streams Processing Language (SPL) is a distributed data flow composition language that is used in Teracloud® Streams. SPL has primitive types, program structures, and definitions that are tailored for streaming data.
A toolkit is a set of SPL artifacts, which are organized into a package. Toolkits make SPL or native functions and primitive or composite operators reusable across different applications.
SPLDOC markup tags document SPL artifacts in a toolkit.
This information describes the comment syntax for the SPL artifacts in SPL files. SPLDOC comments are delimited by the forward slash and asterisk characters.
You can use SPLDOC markup to format text into pages, sections, paragraphs, lists, and blocks of code. You can also apply different typefaces, such as italics, bold, and monospace.
To suppress interpretation by the spl-make-doc command, precede the SPLDOC markup character by a backslash ( \ ), which is the escape character.
The URI is enclosed by square brackets: [<URI>]. You can add a label for the link by specifying the label text after the URI: [<URI>|<label>].
In a toolkit, you can use SPLDOC to mark up links to toolkits, namespaces, operators, functions, types, and SPL files. The name of the artifact is enclosed in square brackets: [LinuxPipe].
To link to a function, you must qualify the function name in the link definition by the parameter types that are input by the function.
You can use the SPLDOC annotation tags to document the interfaces that are exposed by the SPL composite operators and to exclude toolkit artifacts. You can also use SPLDOC annotation tags to document SPL and native functions.
You can embed image files in the generated document by specifying the image file name and a label for the image.
By following the formatting conventions when you mark up the toolkit artifacts, you ensure that the spl-make-doc command interprets the markup correctly and generates the expected results.
