Document Overview
Unified Contact Center Express (UCCX) allows you to manipulate numbers stored in strings but how to do it is pretty poorly documented. This document gives a brief overview of how to modify the contents of a string using the substring function of the Cisco Unified CCX Expression Language.
The Cisco Unified CCX Expression Language
The Cisco Unified CCX Expression language is used by script developers to customize steps or variable values within Cisco Unified CCX scripts. The Expression Language borrows from the syntax of other languages such as C++, C, and Java. The language is described in the Cisco Unified Contact Center Express Expression Language Reference Guide.
The substring Function
The Cisco Unified CCX Expression Language uses strings in the same way Java uses them. For the Sun Java specification on strings, see http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html
.
The sections of the specification relating to the substring function is reproduced below.
<hr />
substring
public String substring(int beginIndex)
Returns a new string that is a substring of this string. The substring begins with the character at the specified index and extends to the end of this string.
Examples:
"unhappy".substring(2) returns "happy"
"Harbison".substring(3) returns "bison"
"emptiness".substring(9) returns "" (an empty string)
Parameters: beginIndex - the beginning index, inclusive. Returns: the specified substring. Throws: IndexOutOfBoundsException - if beginIndex is negative or larger than the length of this String object.
