Functions Summary

Functions defined in this guide can be used in expressions anywhere that a constant or field appears, provided the return type of the function is correct.

A function call consists of the name of the function (upper or lower case) followed by the function arguments separated by commas and enclosed in brackets, for example:

DATE (DAY, LASTMONTH, 2001)

In TIBCO iProcess Modeler, the syntax for the previous example is:

IPEDateTimeUtil.DATE(Integer,Integer,Integer);

A function with no arguments has just the brackets, for example:

DDETERMALL ()

Note: If your iProcess system is set up to use a comma as a decimal separator, you must separate arguments with a comma followed by a space to avoid ambiguity, for example str(2, 2) instead of str(2,2).

In general, the function performs an operation on the arguments and returns a value. In some cases, an argument must be the name of a field that will receive a return value. Otherwise, each argument to a function is itself an expression - a single constant or fieldname, items combined by operators, or function calls.

The following groups of functions are provided. In TIBCO iProcess Modeler, JavaScript classes are provided for the main function types:
