Building the SPL toolkit index

Each SPL project in your workspace contains an SPL toolkit. An SPL toolkit contains operators and functions that might be available for compiling SPL applications. In order for the artifacts in a toolkit to be available for compilation, the toolkit must have an index. The index is a single file that is called toolkit.xml, in the project's root directory. The toolkit index is also used by Streams Studio to display the toolkit artifacts in the Project Explorer view and to make the toolkit artifacts available for content assist functions in the SPL editor.

Streams Studio automatically builds the toolkit index for an SPL project whenever the contents of a relevant source file in the toolkit are modified. For example, if you are editing SPL source, when you click Save, the toolkit index is built to reflect the saved changes.
