Function Tooltips and Decorations
When you float the cursor over a function in the registry, TIBCO BusinessEvents displays the description and syntax in a tooltip 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.
Tooltips
Tooltips also form the online reference to the function catalogs. See TIBCO BusinessEvents Functions Reference.
Decorations Indicating Where Functions can be Called
Some functions have limited application, and some can be used with various product features such as in queries. The second ones have decorations that cluster around the "f" next to the function name in the function catalog. A function can have zero, one, or more decorations. The following figure shows all the available decorations. They are described in the sections after the figure:
Action-Only Functions
Some of these functions have side effects, for example they can change values. Other functions are limited to actions for other reasons. These action-only functions are identified by a small a
at the bottom right of the
icon . For example:
.
Functions that can be used both in actions and in conditions have no decoration. They are considered to have the default validity.
Mapper Functions
Functions that bring up the XSLT mapper and XPath builder are identified by a small
m
at the upper left of the i
, for example:
.
Functions That Can Be Used in TIBCO BusinessEvents Decision Manager
Functions that can be used in TIBCO BusinessEvents Decision Manager are marked with a small table icon,
for example (which is also an action-only function).
Functions That Can Be Used in Queries or with Pattern Matcher
Functions that can be used in queries or with Pattern Matcher are marked with a blue
q for example,
. You can call such functions in a query string and in Pattern Matcher.
They are also valid in rule actions and conditions. See TIBCO BusinessEvents® Event Stream Processing Pattern Matcher Developer's Guide and TIBCO BusinessEvents® Event Stream Processing Query Developer's Guide for details about Pattern Matcher and query features.
