Toolkits
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.

- APIs
  Application programming interfaces (APIs) provide functions that simplify applications development.
- Job configuration overlays
  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.
- Commands
  Teracloud® Streams provides a number of commands you use to perform tasks.
- Operator model
  An operator model is an XML document that describes the basic properties of a primitive operator.
- Streams Processing Language (SPL)
  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.
- Toolkits
  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.
  - Specialized toolkit requirements and restrictions
    Several of the specialized toolkits require RPMs that are not required by the Teracloud® Streams product. There are also toolkit restrictions on some platforms.
  - Toolkits
- SPLDOC markup
  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.

Preparing to customize your application

When creating an ITE application with a wizard, the resulting application contains sample code for your first tests. Your use case surely does not need this code.

About this task

Disable the sample code by switching the appropriate parameter from the on default value to the off value.

Procedure

In the file <PathToYourApplication>/config/config.cfg, find the ite.embeddedSampleCode parameter
Turn off the sample code by setting ite.embeddedSampleCode=off
In the file <PathToYourApplication>/config/config.cfg, find the ite.ingest.reader.parserList parameter
Comment or delete the line that assigns parsers to the ite.ingest.reader.parserList parameter.

If you do not get rid of the sample’s parser list, the ASN.1 parser configured here triggers the compiler to complain about a missing grammar file. You reactivate this parameter when you introduce your parser or parsers to the application.
