Size Operator

Overview

The Size operator performs one of two functions in a Data Workflow:

• Returns the number of characters in a string A string is an object that represents a sequence of characters. Strings typically hold data represented in text form..

• Returns the number of elements in an array An array is a type of object that stores one or more data types. Data types supported in arrays include numbers, strings, and objects..

You'll find the Size operator in the Table group to the left of the Data Workflow canvas.

About the Info Window

Here's a breakdown of the operator's Info window:

Setting	Description
Category	Grayed out and non-adjustable setting indicating the operation type.
Label	Sets the label for your operator, displaying below the operator on your Data Workflow canvas. This field is optional, but set a label if you use more than one of the same operator type. A label helps you identify your operators without opening any Info windows.
Preserve Argument Type	When selected, this setting ensures the argument data type is respected when the operator executes.

Adding a Size Operator

First, configure a couple of Text Field components to collect your end-user's End-users, also known as Express Users, are the individuals accessing an application through Express View. In most cases, end-users are the customers using the product. name and display the result of the Size operator. Then, set up a Data Workflow to return the number of characters in the entry.

These instructions assume that you have a new module open, saved, and with a title.

Configure the Text Field Components

Begin by configuring two Text Field components. The first Text Field component is an input field for your end-user. The second Text Field component displays the result after the data passes through the Data Workflow. To prevent the end-user from adjusting the value of the second Text Field component, you'll select Disable User Input from the Input Behavior setting.

1.

In the Module Builder, drag and drop two  Text Field components onto your canvas.

2.

Enter the purpose of the corresponding component or field. fields, enter the following:

3.

Click Save Component after configuring each component.

Configure the Data Workflow Component

Next, configure a Data Workflow component, to bring data from your name Text Field component into the Data Workflow using an Input operator. Then, add a Size operator to determine the number of characters in the name field. Lastly, you'll send the final result to the characters field using an Output operator.

Your completed module looks like the following:

Preview your module in Express View Express View is how your end-user views your application. Express View also lets you preview your applications to test your configuration and view the styling. This is also the view your end-users will see when interacting with your application. After configuring a module, click Preview in the Module Builder to interact with the module in Express View. and enter a name in the Name field. Notice how the Size operator returns the character count in the Number of Characters field.
