Functions
TIBCO BusinessEvents provides various built-in function to perform the standard tasks; however you can also create your custom function to perform the task as per your requirement.
- Catalog Functions
The functions registry includes various catalogs of functions provided with the product, and each catalog organizes its functions into categories. You can use functions in rule conditions and actions and in rule function bodies. - Built-in Functions
For all the built-in functions, this section lists the main categories in each function catalog (but not sub-categories). - Custom Functions
Using TIBCO BusinessEvents you can define custom functions and expose them as catalog functions or mapper functions. By exporting the project containing the custom Java functions to a project libary, the custom Java functions can be used in other projects. - Ontology Functions
Ontology functions are generated by TIBCO BusinessEvents based on the concepts, events, and rules in your project. - Enabling Extended Functions
Extended functions (sometimes called hidden functions) may be made available by TIBCO Support to address customer-specific use cases. They are also sometimes used to make legacy features available to customers who wish to continue using them. To make them visible in the Catalog Functions view, perform the following actions. - Function Tooltips and Decorations
When you float the curser over a function in the registry, TIBCO BusinessEvents displays the description and syntax in a tool tip next to the cursor. Functions that can be used with various product features are decorated with small symbols that indicate useful information about use of the function. - Temporal Functions and Their Parameters
The set of Standard functions that come with TIBCO BusinessEvents includes functions that allow you to perform calculations on numeric values sampled over time. - Virtual Rule Functions and VRF Catalog Functions
The VRF category of functions (within the standard functions) are used only with TIBCO BusinessEvents Decision Manager. - Cache Related Functions
Various standard functions in the Standard catalog Cluster.DataGrid category enable you to work with objects in the cache. - Indexing for More Efficient Cache Queries
- Oracle Coherence Cache Query Functions
Oracle Coherence Cache Query functions work only with a Coherence cluster. - Structure of a Function Catalog
A function catalog is an XML file that conforms to the schema file function_catalog.xsd.
