Chapter 18 Functions : Built-in Functions

Built-in Functions
For all the built-in functions, this section lists the main categories in each function catalog (but not sub-categories). See TIBCO BusinessEvents Functions Reference for full details.
Standard Functions
The most generally useful catalog, the standard function catalog include the following categories:
Channel functions return information about destinations, and can resume and suspend a destination.
Cluster functions help with multi-engine functionality
DataGrid functions are for use with Cache object management. See Cache Related Functions.
Sequence functions
Collections functions allow you to deal with various collections structures.
Comparator functions
Iterator functions
List functions
Map functions
Set functions
SortedMap functions
SortedSet functions
Date functions allow you to compare two DateTime values using only the date portion of the value.
DateTime functions allow you to perform these date/time related tasks and more: add units of time to a DateTime, compare, retrieve, and format dates and times.
Engine functions allow you to retrieve information about the engine, for example, available memory or the number of rules fired.
Locale functions
Profiler functions
Rtc functions
Variable functions
Event functions allow you to assert, create, and send simple events and perform other event-related tasks, for example, return the default destination URI of a simple event.
Ext functions
The Exception function enables you to create an exception.
File functions provide various useful functions used when working with files.
HTTP functions are used with the HTTP channel
Servlet functions
Instance functions allow you to create and delete concept instances and perform other instance-related tasks, for example, return an instance given an internal ID.
PropertyArray functions
PropertyAtom functions
Reflection functions
StateMachine functions
Log functions allow you to write statements in logs.
Math functions allow you to perform advanced mathematical operations.
Number functions allow you to perform type conversions from and to numbers and return the maximum and minimum values for a numeric type.
SOAP functions enable you to work with SOAP messages sent through an HTTP channel.
String functions allow you to perform comparisons, searches, conversions, and other operations with strings.
System functions allow you to send messages to a debug log, retrieve global variables, retrieve system properties, and write data to a file.
ID functions
IO functions allow the writing and closing of specific files.
Temporal functions allow you to examine and perform calculations on values stored in a property’s history. For information about using temporal functions, see Temporal Functions and Their Parameters.
Calculus functions
History functions
Numeric functions
Statistic functions
Util functions category has one sub-category for working with HashMaps.
VRF functions (that is, Virtual Rule Function functions) allow you to work with decision tables. See Virtual Rule Functions and VRF Catalog Functions and see TIBCO BusinessEvents Decision Manager User’s Guide for details.
XPath functions allow you to evaluate XPath expressions.
ActiveSpaces Functions
These functions tallow you to interact with ActiveSpaces metaspaces. They are used with the ActiveSpaces channels to perform operations on the ActiveSpaces metaspace and spaces connected by the channel.
Process Orchestration Functions
These functions alow you to interact with process jobs. See TIBCO BusinessEvents Process Orchestration documentation for details.
BusinessWorks Functions
BusinessWorks functions are used in ActiveMatrix BusinessWorks integration projects. See Chapter 38, ActiveMatrix BusinessWorks Integration.
CEP Load Balancer Functions
Load balancer functions are used to configure and work with the load balancer. There are two types of load balancer functions:
CEP Pattern Functions
Pattern functions are used with the pattern matcher language for identifying patterns in events. See TIBCO BusinessEvents Event Stream Processing add-on documentation for details.
CEP Query Functions
Query functions are used with the query language for querying data in the cache. See TIBCO BusinessEvents Event Stream Processing add-on documentation for details.
Communication Functions
Communication functions provide a set of catalog functions that enables TCP communication. You can create a local TCP server and a TCP client so that TIBCO BusinessEvents can communicate with data sources not otherwise available through channels, using TCP. See Communicating with Other Sources using TCP for details.
Hawk Functions
Functions to interact with Hawk micro-agents methods.
Metric Functions.
 
DBMS Functions
Database functions are provided for working with database concepts. See TIBCO BusinessEvents Data Modeling for more on database concepts.
Security Functions
These functions are used internally by the TIBCO BusinessEvents Decision Manager add on, for authentication.
Studio Functions
These functions allow you to use the Studio Util functions to build classes and EAR files.
