Create Value Operator

Overview

The Create Value operator generates a new data value in a Data Workflow component in the form of the following data types:

Strings A string is an object that represents a sequence of characters. Strings typically hold data represented in text form.
Booleans The Boolean data type accepts one of two values: true, or, false.
Numbers The Number data type accepts integer or floating point values. The number data type does not use quotes around numerical values.

Most often, you'll use this operator in tandem with a logic component. For example, to create a value of GO to trigger a Plug-In or Calculator component.

The Create Value operator serves as the start of your Data Workflow and does not have an input port. It also includes an argument for determining the value it creates. Connect another operator to the Create Value operator's argument port. Then, in the Expression/Value field, use the _arg value to reference that value.

You can find the Create Value operator under the I/O group to the left of your Data Workflow canvas.

About the Info Window

Learn more about each setting in the Create Value 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.
Expression/Value	Sets the value to create and pass to another operator. You can create a number The Number data type accepts integer or floating point values. The number data type does not use quotes around numerical values., string A string is an object that represents a sequence of characters. Strings typically hold data represented in text form., or Boolean The Boolean data type accepts one of two values: true, or, false. value. To create a number, enter the number here. To create a string, enter the string here, surrounded by single quotes. To create a Boolean, enter either TRUE or FALSE.

Adding a Create Value Operator

To demonstrate a Create Value operator, configure a Data Workflow to create a value of 2 and send it to a Hidden component.

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

Configure the Hidden Component

Before you can add your Data Workflow, you'll configure a Hidden component to store its output.

In the Module Builder, drag and drop a Hidden component onto your canvas.

In the Property ID A Property ID is the unique field ID used by Unqork to track and link components in your module. and Label Text Label Text conveys what the input component is and what information it displays. Enter the purpose of the corresponding component or field. fields, enter valueOutput.

Click Save Component.

Configure the Data Workflow Component

Configure a Data Workflow component to create and send a numerical value to the Hidden component.

Drag and drop a Data Workflow component onto your canvas, placing above the valueOutput Hidden component.

In the Property ID A Property ID is the unique field ID used by Unqork to track and link components in your module. field, enter dwfCreateValue.

In theCanvas Label Text Canvas Label Text indicates the purpose of the corresponding field or component. For non-input components, the Canvas Label Text isn't end-user facing, and only appears in the ., enter dwfCreateValue.

Configure the Create Value Operator

Configure a Create Value operator to create a value of 2.

Drag and drop a Create Value operator onto your Data Workflow canvas.

Configure the operator's Info window as follows:

Info
Category	Create Value
Label	createNumber
Preserve Argument Type	☐ (unchecked)
Expression/Value	2

Configure the Output Operator

Configure an Output operator to send the new value to the Hidden component.

Drag and drop an Output operator onto your Data Workflow canvas.

Configure the operator's Info window as follows:

Info
Category	Output
Component	valueOutput
Action	Value

Connect the output port (right) of the Create Value operator to the input port (left) of the Output operator.

Click Save Component.

Here's how the completed Data Workflow looks:

Configure the Button Component

Lastly, configure a Button component to trigger the Data Workflow.

Drag and drop a Button component Icon

Button component onto your canvas, placing it below the valueOutput Hidden component.

In the Property ID A Property ID is the unique field ID used by Unqork to track and link components in your module. field, enter btnTrigger.

In the Label Text Label Text conveys what the input component is and what information it displays. Enter the purpose of the corresponding component or field. field, enter Run DWF Create Value.

Set the Action Type to .

In the On Click field, enter or select dwfCreateValue.

Click Save Component.

Save your module.

Here's how the completed use case looks in the Module Builder:

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 click Trigger Data Workflow. Then, open the DevTools Console The DevTools Console helps you securely store, build, test, and deploy your software. and run the Angular command The Angular command, or data command, is a tool that displays submission data in a browser's developer console. In Express View, enter the following command in the devtool console: angular.element('.unqorkio-form').scope().submission. You'll see the valueOutput Hidden populates with a value of 2.
