Variables

Introduction

Variables are placeholders for changeable values and can be used to store text strings, Booleans, Lists, Maps (key/value pairs) and numbers, in Teneo there are several types of variables: Global Variables and Flow Variables as well as the variables in Language Objects and Entities.

Naming conventions

A variable needs to have a unique name and usually starts with a lowercase character, indicating the type of information that the variable contains (i.e. s for string, b for Boolean, etc.). When using multiple words, the words should be concatenated with no separating characters between them; the first letter of each word should be capitalized, for example: sUserName, sCompanyName, nHour and iHour.

Global variables coming with Teneo Conversational Modules are prefixed withLib_
